Problems with 2005 Chevrolet TrailBlazer ELECTRICAL SYSTEM

Fuel gauge quit working. *tr

2005 chevrolet trailblazer. consumer writes in regards to vehicle electronic system recall. *smd the consumer stated he experienced an electrical malfunction, that caused the door locks and window controls to cease functioning. sometimes the system was operational and he was able to use it, for a short time. *jb

Possible fatal fire accident. the passenger outside running light 9006 socket found to have burned completly off of the light 9006. this is the 2nd time this vehicle socket has been found to be defective, on 03/15/2012 the driver side socket was burned and was replaced. no help from general moters. see vehicle safety complaints filed with general motors and nhtsa number 10592126. a number of my vehicle defects could have lead to a fatal accident. updated 4/24/2015 *js

My car was starting fine before this. i left work went out to my car tried to start it and it would not do anything other than electrical noises even after i took key out. got a jump (it was quick) the gauge was moving slightly. got to where i needed to be and turned the car off and immediately it would not start. jumped it again got home and the key got stuck in ignition and the lights flashed inside and out of the vehicle all night! *tr

The wiring connecting the blower motor to the resistor under the glove box has melted the connection between the two resulting in smoke and toxic fumes from burning wires while vehicle was in operation with a/c operating on high. shutting the vehicle off stopped any further damage, i have googled this issue and appears as though its a known problem without gm acknowledging the issue and doing any thing to remedy the issue, according to complaints filed with carcomplaints.com. *tr

My speedometer has stopped working in my car an i don't know how fast the car is traveling, done a research online an there are thousand people with the same probably as mine with the exact same make and model of car as i have. something needs to be done cause chevrolet want $500 to replace the speedometer an that is not right. *tr

Tl* the contact owns a 2005 chevrolet trailblazer. the contact stated that the driver side turn signal, brake lights, headlights, air conditioning, and heater were all defective. an independent mechanic stated that the electrical system was defective. the vehicle was not repaired and the manufacturer was notified. the approximate failure mileage was 195,000.

When i fill up with gas my gas gauge reads 0. after driving 40 - 80 mi. it slowly comes back, but reads incorrectly for a few miles. by the time its nearing 1/4 to 1/2 tank is seems ok. i really think its only a matter of time before it quits altogether. i don't trust and use my odometer to estimate my gas level. *tr

The gauge cluster, speakers and occasionally lights stop working at various times, the gauges either register completely maxed out, minimum or somewhere obviously wrong. example fuel gauge way past full, oil pressure gauge reading 0, charge gauge maxed out tachometer completely off the scale and speedometer inoperable. rear speakers work sometimes and bulbs in brake lights and tail lights keep blowing out. the gauges are of most concern as the true values of fuel level, oil pressure, battery voltage and engine temp are rarely accurate (or even close). the speed will not operate at times and occasionally if the vehicle is restarted the speedometer will correct itself. all these conditions create safety concerns on some level from running out of gas in a less than desirable location, driving at incorrect speeds, overheating engine without warning or engine problems. losing a tail light not only creates a safety concern for traffic but creates issues with law enforcement as well. these conditions can happen at any time, driving, parked or idling but the key must be on to power the accessories. type of driving (city, highway, etc,) makes no difference.

Driver's side passenger door left rear door latch on 2002 chevrolet trailblazer ls is stuck. the door will not shut! i have read another complaint for the very same reason and a very similar situation to the ext and there is a recall on the ext but doesn't pertain to the ls. i can't shut my door because the latch won't connect.i opened the door and could not shut it after that because it wouldn't latch. we have looked everywhere and have not been able to locate the part at a reasonable price. i was in the process of selling it, but because of this faulty defect we cannot sell it. we have not been able to get it fixed. no one seems to have the part and we contacted dealerships and they looked up recalls but couldn't help us cause our vin number isn't covered. what do we do now?? *tr

The speedometer will not work properly. it will be stuck and then it will not display the correct speed while driving. this has been a problem with this car for 2 years. also the fan control switch stops working at the same rate. some days it works and some days it won't.

The windows would roll up by themselves, one of my dogs almost got his head stuck in the back window, also seat heater would come on and switch from high to med. to low, then back to high. i had it repaired, cost was $413.00 i'm hearing the same trouble has been reported with the 2006 - 2007 models and some have caught fire. is the new part going to do the same? can i recover any of the cost? *tr

Tl* the contact owns 2005 chevrolet trailblazer. the contact stated that a burning smell was emitted from the control module on the driver's door. the contact mentioned that after inspecting the door she noticed that the wires were melted. the vehicle was not taken to the dealer. the manufacturer was made aware of the failure. the vehicle was not repaired. the failure mileage was 175,000 and the current mileage was 180,000. the vin was not available.

The fuel gauge malfunctions after filling tank - it reads empty immediately and intermittently thereafter at any fuel level. it makes it difficult for traveling any long distance as you are not quite sure how much fuel is available or if it will shut down on me during a difficult situation. we have contacted gm and they want to charge me to check it and this has been reported as a problem for multiple models to gm. this is very scary as i travel long distances to and from work each day - i feel that this puts me in harms way. i don't believe that i should pay to a defective part that gm knows about but doesn't acknowledge. *tr

Starting up my car last wednesday morning,i went to roll my window down on the drivers side and there was a hesitation then it stopped and i smelled something burning.from that point forward i was no longer able to roll my window down or up and lost all functions from that contact pad....in looking thru the varies recalls for this vehicle i noticed the recall for the drivers door module in 2006,2007. if this recall initiated with the 2005 trailblazer in 08/12, why is this model not included in the recall???? why will i have to pay the $400 in repairs somehow this doesn't seem ethical. especially if you knew this was happening in the 2005 chevy trailblazer...i am sure i am preaching to the choir but maybe you can provide me with incite as to the logic!!!!!!!! *tr

On or about this date my 2005 trailblazer experienced and electrical failure during a snow storm. both power door lock and power window switches became in operative and the windows opened automatically while driving and would not go back up. i also encountered an electrical smell in the vehicle, after stopping and turning off the vehicle and then restarting the switches functioned again. i noticed that in the gm recall on 6-30-14, the 2005 trailblazer was in the recall for defective window/lock switch can overheat and malfunction also mentioned is the key switch problem gm had. i have contacted the dealer and been told that without an official recall from gm that there is nothing that can be done. the was in fact a recall but it seems it was "swept under the rug". here is the reference list i found: currently, the following list of vehicles are all subject to the gm recalls on ignition switches: 1997-2005 chevrolet malibu 1998-2002 oldsmobile intrigue 1999-2004 oldsmobile alero 1999-2005 pontiac grand am 2000-05 chevrolet impala and monte carlo 2004-08 pontiac grand prix 2003-14 cadillac cts 2004-06 cadillac srx 2011-14 chevrolet cruze; 2012-14 chevrolet sonic 2013-14 chevrolet trax, buick encore and verano 2014 chevrolet camaro and impala, buick regal, cadillac xts 2007-11 chevrolet silverado hd, gmc sierra hd equipped with an auxiliary battery 2005-07 buick rainier, chevrolet trailblazer, gmc envoy, isuzu ascender, saab 9-7x 2006 chevrolet trailblazer ext, gmc envoy xl yet gm has failed to act and take responsibility. what can be done?? *tr

Saturday night (03/1/14) on our way home it started snowing heavily, the visibility was low and our windows were fogging up and the front heater blower went off on our 2005 chevy trailblazer and would not come back on. while trying to find a place to safely pull over we almost hit another vehicle because we couldn't see through our fogged up windows.. after we pulled over and turned the car off the blower motor came on and continued to run with the car off and the key removed from the ignition, so we re-started the car, and the blower went off and never came back on... then today i went out started the car to warm up the engine and the blower came on. i drove to the store shut the car off and the blower continued to run so i re-started the car and turned it off again and the blower motor stopped. when i re-entered the car to go home the blower once again would not turn on at any speed. so i figured if i didn't have heat at least i had a heated seat but after about 5-10 mins the seat part of the seat got so hot it was burning my butt and thighs so i had to shut it off. then about 1/2 home the blower just started blowing again, i pulled into the gas station shut the car off and the blower motor once again continued to run with the car off and the key out of the ignition so again i put the key in started the car then turned it off again and the motor stopped. this could be a very serious issue with not being able to defrost the windshield/windows in these hazardous driving conditions< plus not having heat in below zero temps is a health hazard as well. ( since we live in such a cold snowy state). *tr

Tl* the contact owns a 2005 chevrolet trailblazer. the contact stated that the low beams failed to illuminate. the contact mentioned that the high beams were able to function. the vehicle was not diagnosed or repaired. the manufacturer was not made aware of the failure. the failure mileage was 120,000 and the current mileage was 122,000. updated 8/11/14*cn the consumer stated the headlights went out, for no reason. updated 08/26/14

Speed control. driving down the road & the speedometer does not register the correct speed. 10 to 20 miles per hour over & even more at times. no way of knowing how fast car is going. sometimes it registers under. very dangerous driving. never knowing how fast or slow i am going. chevrolet also replaced fuel gauge sending unit. rear wiper has not worked for years. tried everything to fix. very unsafe to not be able to see out of my back window. this vehicle has a lot of problems. bought new. very low mileage. *tr

I was driving down the highway in a rainy state with the driver's window partially cracked. water began dripping in onto the driver window control panel, so i closed the window. a few minutes later i went to roll down my window and none of the controls worked. there was a faint electrical burning smell. all four window controls on the panel would no longer function as well as the heated seat buttons. the door lock still functioned as well as the window lock out button. i'm just glad this happened with the window up. swapping the passenger side door control panel with the driver's side door control panel allows you to raise and lower the window, so it is the control panel that is defective. i see that the 2006 and 2007 models were recalled for this due to fires, but no recall exists for the 2005 fires as fires haven't been reported yet. *tr

I just purchased this vehicle yesterday from a dealership. they filled the gas tank up before i drove it off the lot because, they said, "the gas gauge isn't working." i was looking up what it could be and noticed there was a lot of people with complaints of this, 668 people. i suppose i'm the 669th person. there wasn't a recall that i could find, but investigations were being done? *tr

Vehicle's headlamps will power surge, dim while driving periodically. fuel sensor showed constant empty until repaired by the recall. vehicle will occasionally surge forward revving on it's own at random times. the blower resistor pack has burnt up twice, the blower motor has been replaced as well as the melted wires.now the vehicle will not start. the power windows, locks, radio, dome lights, dash lights are inoperative and the vehicle will not attempt to turn over. seems like this vehicle has had a lot of electrical issues. *tr

Speedometer randomly parks on 0 mph no matter what the speed is. the fuel gauge randomly indicates "e" or other inaccurate fuel readings regardless of how much fuel is in the tank. the car randomly stalls when stopped at traffic lights. *tr

Cluster gauges are going out. the speedometer quick working a few years ago and is intermittent at best on a daily basis. it either indicates a lesser or greater speed than actual or just falls to point straight down. i have been using a mounted gps to indicate speed. initial repair cost estimates were $500+ for the parts since they will only replace the entire gauge cluster. with labor, the estimate was in excess of $800. fuel gauge is now inoperative or intermittent. when i fill the tank, the fuel gauge reads way past the full line. having to rely of the fuel to empty and the fuel used computer information along with the trip meter to estimate fuel. received another estimate for a mechanic to pull the gauge cluster and rebuild each individual gauge motor for an estimate of $500. based upon the number similar complaints on this same thing, this appears to be a manufacturing defect that needs to be corrected by gm. *tr

While sitting at a stop light, the fuel gauge stopped working. the gauge went all the way down to "e" and the low fuel level indicator appeared on the display. now when i fill up the tank, the gauge reads empty and after i drive about 20-30 miles it will move up to about 1/4 tank but no higher and sometimes it will still move back to empty that slowly move back up. also sometimes the oil pressure indicator will drop all the way down while idling or in park and the low pressure indicator will appear, but as soon as the gas is pressed, the pressure will go back to normal. also, about 1 1/2 years ago, the keyless entry/alarm/back liftgate lock and license plate light all stopped working simultaneously. i was told that it is probably a grounding wire issue but not definitive. now my liftgate will not lock at all. *tr

Driving at a low speed through a residential area the engine would serge between 2k rpm and 4k rpm. if surging is allowed to persist then it is followed by the vehicle's power steering shut off ultimately ending in the engine shutting off. after vehicle is restarted the cycle starts again after a short period of driving. *tr

My fuel gauge reads empty after i fill the tank with fuel. after driving some duration of time the tank will only read a quarter of a tank full. i find this to be a hazard because i travel for long distance trips and you are unable to get an accurate reading of the amount of fuel that is in your tank. i have read this to be an issue on multiple different websites with the same make and model and i believe that gmc should offer to pay full price and fix the issue because it appears to be a defect. *js

I was driving on the highway when i slowed down & stopped for an accident ahead of me. i did not slam on my brakes and i did not go over any bumps that would jar the vehicle. i was stopped for approximately 20 minutes. when i began accelerating i noticed the speedometer was no longer accurately reading my speed. i was doing around 50 mph, but my speedometer was reading 22 mph. i tried turning the car off once i got home, then restarting it, but it was still reading 22 mph. when i drove it the next day, it started out reading 10 mph, and has varied since then, but still not reading accurately. *tr

Nov.2013 was the frist time we had a proplem, right after that the oil gauge was not working. on an off we have noticed other type of problem that seem to be electrical. for the last year \year an half my gas is all over the place, always stopping to get gas as not to give out. also, my gear and mileage gauge does not work. now have no idea when to change the oil or rotate tires

While traveling we noticed the we were being passed excessively, we looked at the speedometer and saw that we were doing slightly above the speed limit. out of curiosity we checked our speed against our gps / smart phone and saw that we were doing 30 mph under the speed being reported by our speedometer. after searching on the internet we found that 100's if not 1000's are having the same issue or even sometimes in reverse where it states that they are doing 120 mph when they are only doing a fraction of that. in addition we have found that there has been a recall on this same part on other gm vehicles for the exact same reason but the trailblazer was excluded for whatever reason. how can not knowing how fast your actually going not be a major hazard especially with a proven history of failures. *tr

I went into town to grab dinner and as i am driving along, my headlights shut off. the only thing that remained on, were the orange turn signal lights. i frantically turned the headlight knob on an off and nothing happened. i was looking for a place to turn off the highway, however it was night time and i had no headlights. i ended up pulling over to the gravel side of the road, and turned the car off. now i am stuck on the side of the highway at night time, with no working headlights. i turned the car off and got out, tapped the headlights and looked for any physical damage and did not find an answer. upon starting the car again, it sounded like someone had turned on a vacuum cleaner. the noise pitched up for about 5 seconds before pitching back down. after re-starting the oil pressure gauge moved from its normal position at "12 o'clock" to an abnormal "6 o'clock". i tried to call onstar for a vehicle diagnostic, however now my radio would not work either. i tried the headlights again, and they still would not turn on. i turned on my high beams, and proceeded back home. while en route my speedometer was reading 10mph over my actual speed. when i pulled into my driveway and turned the car off, the speedometer stayed at 10mph. i find it very hard to believe that all of these things happened all at once as a coincidence. this is a huge safety concern as i lost the ability to see at night, as well as the ability to monitor my speed all while trying to drive. not to mention all of the motorists who were blinded by my high beams on the way back. *tr

Odometer now reads zero, do not know speed. gas gauge reads zero. if rear defrost is on and a/c unit is on the fuse for the system will blow. radio system is not functioning properly. *tr

Tl* the contact owns a 2005 chevrolet trailblazer. while driving various speeds, the front driver side power door lock and window failed to activate. the vehicle was taken to an independent mechanic on numerous occasions. the vehicle was repaired, but the cause of the failure was unknown. the failure recurred after the repair was performed. the vehicle was not repaired for the most recent failure. the manufacturer was notified of the failure. the approximate failure mileage was 91,000.

Tl* the contact owns a 2005 chevrolet trailblazer. the contact stated that the speedometer failed to operate normally without warning. the contact also mentioned that the fuel and temperature gauges failed to operate. the vehicle was not taken to a dealer or independent mechanic. the vehicle was not repaired. the manufacturer was notified. the approximate failure and current mileage was 48,000. updated 11/29/13*lj

I have lots of issues with my trailblazer. just today my a/c quit blowing. i've had enough so decided to research online. glad i did because it seems that there really is a problem with these vehicles. first off i my gauges(all of them, including fuel gauge) started to act up. sometimes they worked and other times they were way off or just hanging. the fuel gauge and speedometer no longer work at all. this all started years ago. i have just lived with it as i don't have the money to fix them. my headlights started going on and off at random about two years ago. also something i have just lived with as i don't do too much night time driving. now that my a/c is not blowing i will have to do something. i live in florida, and am not going to allow my daughter and i to sweat everyday back and forth from work and school to home. this sucks!!! they really needs to recall the whole electrical system for these vehicles. this is a fire hazard due to the connections getting so hot they burn up.

The window and lock controls on the driver door handle just stopped working leaving my window open. it is not a fuse. i began looking for other issues online and have come across this issue on earlier model trailblazers. i am in a cold climate as the other recall is applicable to. *tr

Driving on the highway to the shore my speedometer increased to 95 mph. when we parked it was stuck on 10. since then it has happened many times. when i park i have to check what it stops at. sometimes, its 10, 20, 30, etc. i have tried disconnecting the negative battery cable and that helps as a temp fix. my dealer says there is no recall, but i saw online a class action suit against gm, but not for trailblazers. this is a gm issue and i don't have the money to get it fixed. updated 03/11/14

While driving my vehicle, the speedometer stops working. it works when you start the car, then when stops are made, it stops working altogether and goes to zero. i have researched the internet, and this is a huge problem for this vehicle, and gm should have recalled this faulty part years ago. when i took it to get repaired the service place said it was a cluster that would cost over $500 to get fixed. once again, this is a huge problem and gm should take care of ts customers. *tr

The speedometer is stuck and will not move. *tr

Multiple times my trailblazer has stalled without warning. it tends to happen when i am in a stopped position. whether it is at a stop light or just stopping in general. it takes a minute and then restarts. *js it has also multiple times lost head lights. the last time was at 9pm while driving home with my children in the car. my headlights went out i had to pull over and the only way my lights would work was if i held my high beams on.

Driver side master power window switch does not work the driver side window at all! out of the blue this stopped working. further research shows that the 2006-2007 models were recalled not the 2005! really, this car is "currently registered in a cold weather state which uses salt to clear the roads" (direct quote from general motors and isuzu recall 258,000 suvs, the associated press, august 19, 2012) since 12/2005 which is when the vehicle was purchased. just because my vehicle did not have a fire "yet" but i have the "exact" problem which arose before these vehicles did catch fire, mine is not recalled? not only was the transmission recalled in 2008, i had a problem with the "blower motor" not working when you turn on the heat. you could only turn on the heat to no. 4. the truck was taken for service on 1/10/06, 1/30/06, 2/7/06 and 2/17/06 which was not even 2 mo. after purchasing said vehicle before the problem was corrected. in 11/06 the "fuel pump module" was replaced and covered "only" because i had the extended warranty and i had to pay the $100.00 deductible, because i had gas but it was not registering. again, i continue to have this problem. when calling gm on 7/24/13 about the window switch recall, i now find out that there is a "special coverage" for the "fuel level sensor". this is covered until 7/24/14, per gm (866-694-6546), unless you have more than 120,000 something miles. was not sure of the mileage exactly since mine is below that figure. the window switch is a serious malfunction that needs to be covered in "all years" of this vehicle. while sitting at a red light with your foot on the brake, the vehicle will just rev up and want to take off. i guess this isn't a "big deal" either. you can't even listen to the radio to distract you with all these problems going on because the radio only comes out of "one" speaker! go figure, it is gm! *tr

The engine light constantly comes on even after i had a tune up. i had diagnostics done and there is some type of fuel misfire. two winters straight i have had issues with the power steering lines bursting and replaced 3 times. the speedometer malfunctions, most of the time it just stays at zero. if gm uses a lot of the same parts to make multiple models why has the 2005 trailblazer not been recalled? i was told the gm envoy has the same engine and other inner workings as my trailblazer so why wouldn't their recalls apply to my vehicle especially if i may be having the same issues. *tr

Tl* the contact owns a 2005 chevrolet trailblazer. the contact stated that all the functions of the driver door had failed. the vehicle was taken to the dealer where the technician diagnosed that the door module needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure. the failure mileage was 100,000 and the current mileage was 115,000.

While putting the truck into 4x4 hi, lo, or all wheel drive, the transfer case never does fully put it into 4x4. while driving, the dim lights turn completely off. the brights work, but the dims do not. these will not turn back on until the truck is shut off or a proper bump is hit. the heater blower in the front sometimes will nit come on. the back will be blowing, not the front. also if a bump is hit improperly, the back speakers will start buzzing. *tr

Fuel sensor seems to be failing as is with many other problems with the electrical system on this car including a broken speedometer at 60,000 miles. this car seems to have far too many sensor or electrical issues and given the safety implications of speedometers that suddenly fail and fuel sensors that fail, it would seem prudent for someone to realize that these issues pose a severe safety hazard to all. after research on the internet, speedometers and fuel sensors seem to be a common issue with trailblazers. please research the electrical system and sensors more closely. *tr

2005 chevrolet trailblazer. consumer writes in regards to vehicle fuel gauge sensor issues. *smd the consumer state the first time the fuel gauge starting acting erratic was in 2007. the dealer informed his wife, the vehicle had ran out of gas, even though the gauge indicated there was 1/2 tank of gas. the consumer stated he continues to experience an erratic behavior of the fuel pump and the low fuel indicator light illuminated. the latest preliminary diagnosis was the vehicle was unable to sustain an idle, because of the erratic fuel pressure (fuel pump). the consumer also stated the vehicle has electrical problems and the oil pressure gauge was inoperative.

The fuel gauge in my vehicle stopped working. i did some research and this seems like a common problem to trailblazers that gm is ignoring. running out of fuel can be very dangerous especially on busy highways. so i think this should be a safety issue that needs to be addressed as soon as possible. *tr

I had just filled up my suv, and while on the highway, my fuel gauge started dropping within a minutes time, to 3/4 tank, 1/2 tank, 1/4 tank, then the fuel light came on and stated i was on empty. i didn't smell gasoline, but the gauge then started going back up, then down and went haywire. after some of the gas was used, it went back up to almost full, but after a bit, it dropped back down to half tank again. every subsequent time i fill up, the gauge does the same thing. another incident that has been happening for the last few years is the head lights dim and get brighter. this doesn't happen all the time, but at least three times a week. i didn't think too much about it until i saw other complaints on this website about the same thing. *tr

Vehicle would not start. had it towed to mechanic shop. battery was completely dead, though the battery was only 1 year old and was a very expensive ac delco 6 yr battery. mechanic changed the alternator and the battery and everything tested the same. put old battery and alternator back in, as battery he charged was holding the charge ok. could not locate source of problem. the next day, the dash lights were not working, nor the interior lights. as i drove along the highway, the dashlights blinked and then stayed on. ceiling light works intermittently. the alternator shows that it is charging very hard. according to other incidents reported on the internet, there is an electrical problem in the 2005 trailblazer that may or may not be associated with the passlock anti-theft system, but in any case, shows slow leak of electrical current that slowly drains the battery 24/7, until the battery is dead. why is no recall issued making general motors responsible to find and fix this problem without cost to the owners of 2005 trailblazers. i spent $130.00 at the mechanic shop and they could not find what the problem is, much less fix it. my vehicle is parked in a garage most of the time, and there is no reason for this malfunction other than faulty gm part somewhere. our local chevy dealer told me they think the problem is related to the passlock anti-theft system but they have never been able to nail it down. they reference a vehicle which they kept for two weeks for diagnosis of a "won't start" complaint, and the vehicle started some days and not other days with no pattern to the malfunction. *tr

Tl* the contact owns a 2005 chevrolet trailblazer. the contact stated that while driving at various speeds, the speedometer failed. the contact was unable to see current vehicle speed. the vehicle was taken to the dealer where it was found that the instrument cluster had failed and needed to be replaced. the manufacturer was contacted. the failure and current mileages were approximately 113,000. *tr
