Problems with 2005 Chevrolet TrailBlazer ELECTRICAL SYSTEM

The speedometer isn't working. i've been hearing how common this issue is. every now and then it will jump to a random spot when i start the vehicle and stay there. but it never moves while driving

In motion or parked my speed and my tac just stop at random numbers. i have to shut my car off if my speed is stuck. everytime i do this my speed drops 5 mph so if i'm stuck at 20 i have to do this 4 times just to get back to 0 mph i have called chevy . they told me it will cost me over $800 to fix this. kinda strange the recall doaent effect only the trailblazers don't you think. i have been in the automotive feiod for over 10 years now and i know alot of chevy have had this recall so it's time for you guys act.

Vehicle purchased 2008. it had 35,412 mi. in 2011 the vehicle would have a rough idle and stall in traffic. sometimes as many as 3 times on a six mile round trip. always would stall driving around town. i had replaced cam vrr temp sensor fuel throttle. all coils plugs water pump battery motor supports belt windshield washer bottle and motors flush fuel lines. wheel hubs and bearing rounds crankshaft and power steering pulley power steering pump oil changes 2500 to 3000 miles synthetic oil. all fluids changed and flush rear differential transmission shifter cable. several diagnostics at chevrolet. left there they drove it cut off once. finally, i kept watching gauges oil pressure dropped 44 to zero. car cut off rectangles it pulled over wait 30 mins. no oil on dip stick. called firestone took it there. oil sending unit defective. changed all oil. they found it. this was a big safety issue over several years for me. afraid get run over by truck. the vehicle has not cut off one time. i reported to chevrolet. put in bank there. please check oil sending unit. seen numerous trailblazers with this issue. on the web.

I am experiencing all issues identified with recall due to door switch sensor being defective. intermittent working of door locks not locking or locking and won't unlock . windows won't work sometimes, and sometimes they will . lights won't shut off in interior, or won't go on . delay feature where radio , and other features stay on after turning ignition off , and still in vehicle won't work , and sometimes do work . these things happen when vehicle is either moving, or not moving in park . they happen both city driving, and highway as well. all of these crazy electrical problems began several months ago, and when in the vehicle and i am in park, and shut off ignition, and the doors won't unlock, the key fob won't work to unlock doors either, and i am trapped inside vehicle until someone is close enough to hear me yelling for help, and can hand them my keys out of sunroof in order to put it into lock on the door and manually unlock the door. i absolutely must have this fixed because nobody near my residence to either let me out of vehicle, or to call . closest person i can call is over an hour away . i am on disability of 720.00 a month and can't afford this repair .

Driving in city speedomoter quit working properly. dont know what speed is while driving car has 33000 miles, has not been driven in 3 years as it was my fathers and he no longer drives as he is 97 years old

Our vehicle died at a turn signal light in a dangerous intersection. no warning from the vehicle as it was running normal. it would turn over but no start. police force a tow out of the busy intersection right away. it starts up at the mechanics. they tested fuel filter and other stuff. we get on the highway in traffic and get 6 miles out and no warning we die and had to push the car to the shoulder on in dangerous conditions. sit for 2 hours and it fires up. so we found shade and waited for cool down. 2 hours away from home and it took us 9 hours to get home. we drove it to the store and when we were done shopping it fired up. went around the corner to other store and shopped 2 hours and came out and it would turn and no start. tried starting every 30 minutes to hour from 9:30pm to 1:40am and then it fired right up then drove 30 minutes to home. after researching and finding quite a few with same year make and model having the same issue we found that it is the pwr/trn relay plug in area in the fuse relay center. when we broke the plastic off the relay and wrapped a rubber band around it so it's constant contact and plug it in, it will fire up every time. i can drive it all day like that with no issues. i have to turn the key from running to accessory mode then remove the rubber band and then power off the car. don't want to fry com. the relays are good and problem is the fuse relay center. chevrolet said themselves that this model is notorious for fuse relay center problems and usually require replacement. it's a known defect. there are two pictures attached from one of the other people with same vehicle same problem and in order to make his fuse relay center work properly he had to wire/reroute his pwr/trn relay as seen in the picture. this needs to be investigated as this is a well known issue with chevrolet and the trailblazer.

The headlights go off after a while of use as if the over heat and go off once they cool off they come back on but they go off after about 15 mins of use. only the brights will work at this time. so not only is it a safety hazard to me that my lights just go off out of nowhere then i have to turn my brights on which is a safety hazard to other people and against the wall you have a recall on the 2006 model for the same problem why would you not have the recall on the 2005 model that obviously has the same issue they go off on back roads they go off on the highway they go off in the city they go off in the country they go off anywhere that i'm driving anytime that the headlights are on that will go off after about 15 minutes of use whether the car is being driven or it is stationary. this imhas been a problem with this car for many years but i just recently bought it for myself and i feel it's an issue that you all should resolve i have looked online and there a lot of people having the same issue

Takata recall all the gauges on my trailblazer have stopped working except the gas and temperature gauge. while i was driving 2 weeks ago on the highway my gauges just quit working and the needles dropped to the bottom.

Control panel on drivers door is no longer functional, during a heavy rainstorm i got out of my truck, closed the door and ran to my house. the next day the controls no longer worked. this is not the first time i've left my vehicle while raining but the first time the controls stopped working. this was a recall item in other years 2006-2007. chery does not recognize this being the same issue in the 2005 model. chevrolet trailblazer recall - #13v248000. fluid may enter the driver's door module, causing corrosion that could result in a short in the circuit board. a short may cause the power door lock and power window switches to function intermittently or become inoperative. the short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.

While driving at night i have an intermittent problem where the headlamp low beams just go out. i have moved relays around but it doesn't correct the problem. i have been stopped by police several times because i am blinding other drivers because i have to drive with brights lit. i see they recalled the 2006 and later models for this problem. i work at a shop and we see , on average, 10 per year that are 2005 and that's just in our small community. if i set a half hour, sometimes an hour then the dims start working again. the most recent time was may 5th of 2018

Gauges (fuel, battery and oil) quit working. so now the check engine light is on.

So i can't really drive at night as my dim lights just stop working. yes i have brights and i have been stopped twice and ticketed once for the issue of failure to dim. this is ridiculous as they are recalling all the newer models but not the 2005. i am frustrated because i have even moved relays around but nothings helps except to set on side of highway for a couple hours before they apparently col down? you tell me

My gauges on the instrument panel has stopped working. first, about a year ago my tac and oil pressure gauges stopped working. then a few months later, the temp gauge. now, last week my gas gauge stopped.

My speedometer stopped working my gas gaige stopped working and my odometer went out cant see the milelage and i dont know how much gas is in the take,and the speed is mot working.i remember a recall awhile ago if you had the problem they said and i didnt at that time i think it was 2011

When you turn the heat or air on high the red wire on the blower motor resistor gets hot and melts and i have 2 little girls that ride in this vehicle. this isn't normal

Rpm, gas, and voltage meter are not reading properly at all. everywhere u go everytime u start the truck up it does not read properly.

Gm ignition switch problems/recall. on 07/18/2014 i took my 2005 chevrolet trailblazer (32,262 mi.) in for service to fix/replace parts: faulty ignition switch. today, 06/02/2017, my trailblazer (35,193 mi.) is still having the same problem. a faulty ignition switch which is causing abs and parking brakes lights to come on and stay on, the blower for air/vent will not work and since these parts are all connected electrically, i once again have to replace the faulty ignition switch. i was never reimbursed for the first recall. please look into this matter. i would hate to get rid of a perfectly good vehicle, that has held up all of this time, i only have 35,200 miles on this 2005 chevrolet trailblazer. will the ignition switch keep failing on this vehicle? thank you.

Gauges on the instrument panel stopped working. there are currently 3 gauges not working on my instrument panel including the speedometer and the gas gauge. this is extremely dangerous not knowing when your gas tank is empty or how fast your going. the gauges do not work whether i am driving or stopped.

I bought this car used in 2009. it had about 60000 miles on it. 1) the first problem i had with it was a burnout of the hac blower plug, that part of the wiring harness had to be cut out and replaced wth a completely new plug( both halves) and rewired in for a cost of 125.oo and 3 hours of labour. i looked this up on the internet very common problem 2) rider side door control panel stopped working with strong odor of burnt plastic. again looked up and found there was a recall, but only 2006 vehicles 3)brakes burn out of rotors only on rightside- left side rotors were fine, brake job with replacement of 2 left rotors i front piston amd all 8 pads 650.00. failure occurred while driving on city street 4) failure of ignition switch with erratic electrical function of running lights, radio and dashboard instrumentation. happened on the road early twilight very dangerous had to get a local toll for 75.00 all of these failures have made me very wary of driving this vehicle. they occurred at various times over last 4year some have been repaired as noted above. presently waiting for igniton system repair.

Speedometer does not work any longer,4 wheel drive does not engage

Fuel gauge always shows empty, not working. no way to know how much gas is in the car. oil gauge not working.

When driving vehicle both left and right low beam headlights go out. the first time it happened was when i was driving long distance in the dark. had to drive with my high beams on for the rest of the trip. there is no specific time frame, but generally it happens anywhere from 10- 30 minutes of driving. i suspect it is heat related. i have changed the headlight relay #46, bit it only fixed the problem for a week. again the lights will go out after driving several minutes. i noticed there is a recall for a similar issue on the 2006 chevy trailblazer. could this be the same problem with my vehicle. there are also multiple forums explaining the same exact issue with early 2000 model trailblazers. this issue happened approx 6 months ago. last week we ran into another problem. our abs light comes on periodically. like the headlights going out, the abs light comes on after driving the vehicle for a certain amount of time anywhere from 10 minutes to 30 minutes. again, i feel it electrical components/wiring is overheating and causing these issues. i feel there should be a safety recall for this this issue as it is affecting hundreds of customers usa wide.

The low beam headlamps fail simultaneously. this occurs while driving at night. i have replaced the hdm solid state relay twice, but after a time. 6 months to a year, the failure occurs again. once the hdm module became to hot to touch upon failing. this last time, the third, the lights may come on again after some time has passed. it is as if the module is short circuiting or overheating leading to a short circuit.

Tl* the contact owns a 2005 chevrolet trailblazer. while the vehicle was parked in the driveway without the keys in the ignition, a fire originated from the driver's door near the window switch. the contact extinguished the fire. the vehicle was not diagnosed nor repaired. the manufacturer was not notified of the failure. the failure mileage was 159,000.

Tl* the contact owns a 2005 chevrolet trailblazer. the contact stated that while driving at approximately 45 mph, the check engine warning indicator illuminated and the vehicle stalled afterwards. after approximately two minutes, the vehicle started normally. the vehicle was driven to the dealer and the diagnosis was that the abs sensor, the oxygen sensor, the brake pads, the cluster module and the fuel sender lever had to be replaced. the vehicle was being repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 178,000. the vin was not available.

The low fuel gauge indicator remains on even after i fill my fuel tank. the indicator never goes off at anytime.

Tl* the contact owns a 2005 chevrolet trailblazer. the contact stated that the vehicle's door power switch failed to function. the vehicle was not diagnosed or repaired. the manufacturer was notified of the failure. the failure mileage was 120,000.

Tl* the contact owns a 2005 chevrolet blazer. while driving at approximately 30 mph, the low beam headlights were activated and illuminated intermittently. the instrument panel warning indicators also illuminated. in addition, the high beam headlights experienced the same failure when activated. the vehicle was not diagnosed or repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 150,000. the vin was not available.

Tl* the contact owns a 2005 chevrolet trailblazer. while driving at 60 mph, the headlights failed. the vehicle was able to restart and the headlights resumed to normal operation. the contact was advised that the vehicle was not included in nhtsa campaign number: 14v755000 (exterior lighting). the vehicle was not repaired. the approximate failure mileage was 152,000.

Fuel guage is not accurate. when the tank is full the guage registers empty.

The driver's door master power window switch module got hot & started smoking. removing and looking at it showed that it caught on fire. it looks like it started somewhere on the circuit board. it seems identical to the problem listed on the 2006 chevy trailblazers. (nhtsa campaign number: 15v599000) it happened in 2015. i've just been holding onto the part because i didn't know what to do with it & the local dealer wasn't any help.

While driving, the driver side window control started smoking, then it quit working

The airbags will show that they're not enabled even with a passenger sitting in the seat.then it would come on as being on but no passenger in seat. a lot of sensors have popped up in the electrical panel, on top of that the car kinda shut down on me and started going 10 miles per hour, as i was going out in traffic.

Speedometer does not work most often and when it does, does not show an accurate reading.

Tl* the contact owns a 2005 chevrolet trailblazer. while driving approximately 45 mph, the driver side switch for the windows failed to operate. after the vehicle was powered off, the power lock switch was engaged and the windows closed but failed to operate again. the vehicle was taken to a dealer, but was not diagnosed or repaired. the manufacturer was notified of the failure and stated that the vin was not included in nhtsa campaign number: 13v248000 (electrical system, visibility). the failure mileage was 182,000.

The headlights work then shut off. (on the way to work in a downpour, no less) dashboard lights partially working. (if i go over 40 mpg can't tell what my speed is) was working correctly for a couple of days now nothing. i checked for recalls and there are recalls for 2006-20xx (nhtsa 14v755000 ) just wondering, after finding on the internet, numerous 2005 owners with same problem, why this model wasn't included in the recalls? i would like to file a complaint on the potentially deadly problem of the 2005 chevy trailblazer that should be corrected and included in this recall. thank you *tr

While traveling about 15mph through a boat yard with my heater on high (5) i smelled a hot metallic odor, but thought it was just from some welding be done on a steel boat. then my heater quit. i turned it down to 3 or 4 and it ran a little longer and quit completely. when i got home i checked on a trailblazer website to find information and found that the blower resistor speed control unit was a common cause of this type failure. upon removing this resistor pack i found the plastic plug connection on it had gotten so hot that it melted and fused the plug in the socket. when i did finally get it apart i found that one of the connector pins had burned completely off. insulation on three or four wires had also been burned. luckily there had been no major fire. *tr

It all started whaen i filled the tank of gas even when full the gauge went crazy never marked the real amout now all the panel is not functioning ans sometimes turns all light and stops working air windows etc.

The speedometer in my car started not working a week ago.. it would say i was going 70 and in reality i was only going 55. now it starts out at 110mph when i start driving....making it really difficult to know how fast/slow i am going. i have read many articles of this happening with this make and model of vehicle. *tr

Dash controls and readings all go out. speedometer does not show speed. oil pressure gauge does not read correctly. *tr

Our speedometer does not work any longer and as i read, this is a common problem but there is so recall on the vehicle. *tr

Tl* the contact owns a 2005 chevrolet trailblazer. while driving at various speeds, the headlights would intermittently operate. the vehicle was taken to the dealer who diagnosed that the fuse box needed to be replaced. the vehicle was repaired. the manufacturer was made aware of the failure. the approximate failure mileage was 115,000. updated 4/15/15*cn updated 9/20/2017*cn

Multiple times while driving the headlights will malfunction and turn on and off, at random driving speeds under many different conditions. i continued to drive the trailblazer even after this occurred. just not as often. if the heater was on while driving and the headlights would short the heater would stop and then turn back on. the fan turns on at random, first it turns on when driving at random times. the fan will turn on at random times with a higher speed and sound. i have had the inspection completed multiple times with a mechanic re-assuring the issue although it has been happening frequently. the check engine light is on all the time due to computer error and is a $500.00 fix. this has all happened and been reported within the first year i bought the vehicle from kendal motors in lewiston idaho. i find that the amount of work to fix this vehicle is overwhelming and to see that this vehicle was under 100.000 miles is financially distressing. i have already had the fuel pump portion removed and fixed twice, i had to purchase a locking cap. the stereo repeatedly jams with new cd's even. *tr

Speedometer stopped working a few times until it completely has gone dead and doesn't work at all. my trailblazer also has stalled if stopped at a red light more than once. *tr

The speedometer is stuck and will not go back down to 0mph when stopped. *tr

I noticed my battery guage quit. then after starting my truck a few different times, the gas guage read differently. then my speedometer wduld stick on 100 when i was doing approximatly 60. then the speedometer would not work at all. there needs to be a recall on it. my friend has a 2005 also and her cluster pannel went out too. its a 400.00 repair. this has happened to quite a few 2005 chevrolet trailblazers from what ive read online. come on general motors. you need to recall these models.

First my temp gauge started reading incorrectly. the needle would point way outside the normal range of the gauge, often straight downward. then my speedometer stopped working. at a full stop it says i'm going between 50 and 65 mph. i've read online that this is apparently a big problem for this model and year (several repairs per week) and yet there's no recall? *tr

Lights go out/dim while driving. no additional electrical items in use-heater, ac, gps, radio, cigarette lighter. does not appear to be affected or caused by speed, acceleration, deceleration. fule tank will sometimes register empty while mostly full. do not notice problem during daylight driving.

Letter from senator durbin on behalf of constituent re gm recalls. *smd 2005 chevrolet trailblazer. the consumer stated she inquired on several occasions about a recall, regarding the malfunction of the speedometer, gas gauge ad oil gauge. all three of them stopped working. *jb

I bought this car at the end of march of this year with under 100,000 miles. the first thing to go was the gas gauge, about 2 months after i bought the trail blazer the needle went south. it actually hovers around 6 0 ' clock. then a couple nights ago driving home i had the cruise control on, i took it with the hand button and looked down and the needle never moved, it was stuck at 65. it's been 3 days and the needle has moved but the wrong way, to the right going up 75, 80, 90, then back down to 65 and staying there. i have looked into replacing the gas gauge and i was told the entire dash would have to be done at a price of 1200.00, i should not have to do this, chevrolet should be held responsible. *tr
