Problems with 2004 Chevrolet TrailBlazer EXT ELECTRICAL SYSTEM

Instrumental panel/ gage cluster. all gages continue to fail spiking all over the place prior to failing. air bag light continues to blink on then off randomly

Fuel gauge not working alone with all the other gauges and turning signal not working

Tl* the contact owns a 2004 chevrolet trailblazer ext. the contact stated that the entire instrument panel failed to operate. in addition, the speedometer, tachometer, and fuel gauge failed to function properly. the vehicle was taken to an independent mechanic who stated that the instrument panel cluster would need to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 98,000. the vin was unavailable.

The headlights intermittently will not work (lowbeam only). it happens at night many times and i will have to drive with the bright lights or fog lights. sometimes the entire dash lighting will go out as well including the speedometer. it's almost as if the electrical portion of the ignition has failed. it has been happening intermittently for about a year. *tr

Speedometer dropped to zero. stopped vehicle and restarted. speedometer started but wouldn't go above 35 mph. i had a gps speedometer on my phone and it was registering 55-60 mph and the vehicle speedometer would display 25-30. after a cool night it might work correctly for 4 or 5 miles then it either drops to zero or falls to the 10-25mph range. sometimes restarting the vehicle will get it to work again for a short time. when it is failing the needle drops below the 0 mph towards the mileage. when it seems to be working somewhat it stops at 0 mph or just above it. this should really be a recall ! thank you *tr

We were doing our normal fill-up (truck was off) and after we filled it up & turned it over, the fuel gauge shot way over the 'full' mark. every time we turned the vehicle on, the fuel gauge was reading differently, i have no idea how many times it was right. the oil pressure and battery charge gauge have also been giving false/sporadic readings as well. after much searching, i found the root cause of this to be a very common problem not only in the trailblazers but the tahoes and several other of their vehicles (the instrument clusters are faulty). given the expansive nature of this issue, and the potential dangers of not knowing your speed, fuel level, oil pressure or rpms, i'm having problems seeing why this isn't a recall already. it seems to happen more in the 2003-2006 models more than others from what i've found as well. *tr

Lights started flashing, gas gauge went to empty, car died. restarted drove 1/4 mile died. stereo system completely failed (whole unit). keeps popping circuits changed out still doing. cannot shut off heat due to banging sound. car speeds up and down on own. cannot read gas gauge correctly, not sure how full tank is. *tr

Speedometer gets stuck at random places. impossible to know how fast you are going. gm recalled for this but not on trailblazers. *tr

2004 chevrolet trailblazer ext with 76,500 miles on it. while driving to work i noticed the oil pressure gauge was reading maximum. i immediately pulled over in the dark on a busy hwy to check oil and it was full. then approx 2 weeks later the oil pressure gauge is pointing down and stays there. now the speedometer is reading 80 mph even when stopped. this is a huge safety issue. i have serious doubts as to whether the gas and water temp gauge is reading correctly. there are numerous complaints already filed about this model and many other chevrolet models. recalls have been made on some models for this problem, but not this one. chevrolet needs to recall this model asap and correct the infamous problem that they are well aware of. this is a very costly repair and one that the consumer should not have to pay for. *tr

The speedometer started to malfunction while driving 40 mph north bound on davis blvd. the speedometer was reading 80 mph then when stopped it was still reading 80 mph. it then moved past the gauge not allowing to know my actual speed. this to me is a car safety issue because we never know how fast we are going. the gas gauge has been malfunctioning for more that 24 months. the caution light (yellow) turns on when you need to fill the tank so we have been using this light to fill the car with gas. the gauge needs to be repaired. since the car is not abused we fill this is something which should have lasted the regular 100,000 miles before there was a problem. the warranty period is over. from talking to other users and repeated searches online it seem to be a regular failure item. i believe it should be repaired by general motors corporation. many drivers have had to spend lots of money to have this item fixed in less than average mean times between failure of (100,000 miles). *tr

All gauges on control panel not working, but all service lights come on check engine, abs seat belt, reduce power, battery lights. speed and fuel are impossible to know as well as warnings to observe from lights. 2004 chevrolet trailblazer, speedometer will show a faster speed than you moving or will go to 0 while on the freeway. the tach has the same problem. this is a serious safety issue and it should be recalled now. i heard that they had the same issue on pick-ups and they were recalled. most instrument backlights have burned out preventing the speedometer and other gauges from being seen at night. very dangerous. quick search on internet results in a severe epidemic of this problem with all gm suv's. a class action lawsuit resulted in a nationwide recall for this problem for all similar vehicles but not the chevy trailblazer or gmc envoy. this seems to be a criminal act by gm. something needs to be done to protect owners of these vehicles. driving down highway headlights go out..while driving at night the low beam lights went out, i had to drive home with high beams on, http://www.aboutautomobile.com/complaint/2004/chevrolet/trailblazer/electrical+system check out all these other complaints there are hundreds of them and i am one of many. this is so dangerous and a safety hazard to others as well, please get us a recall on these cars the expenses are tremendous. *tr

The electrical system on my 2004 trailblazer ext is not operating properly. the tachometer doesn't register, nor does the battery gauge and uncertain if the reading on the oil gauge is accurate. the fuel gauge is not operable, the needle is either pass e(empty) or pass f (full), i'm constantly re-fueling for fear of running out of gas. when first starting the engine, the speed indicator might register correctly, but then it falls below 0 mph while traveling speeds of 35 to 55 mph and other times it may indicate speeds in excess of 100 mph. problems with the speedometer first started in june 2012 , i used a gps to keep track of traveling speed. afterwards, the other gauges started to malfunction. no parts have been repaired or replaced.very concerned about safety issues, as i occasionally transport my grandchildren to appointments. has chevrolet made any amendments to correct these problems? assistance needed please. *tr

fuel gauge stays on empty and oil temperature gauge stays at 260 degrees. the speedometer sticks and resets incorrectly at random intervals. *tr

Car felt "stuck" in gear, wouldn't accelerate, low on transmission fluid. added more fluid, replaced speed sensor, camshaft & crankshaft sensors. still having issues with rpms going high, car slamming from one gear into another. also cannot run heat while driving, fan draws power & causes engine to stall out. car also burning through gas very quickly. *tr

Vehicle was being driven when all dash gauges failed. particularly concerning was the failure of the speedometer. gm has admitted that other vehicles have had this problem and have paid for and installed replacement dash clusters on some models. the 2004 trailblazer is not covered as there has not been enough occurrences of instrument cluster failure reported. *tr

The speedometer is not registering the correct speed, jumps around while driving and has affected the cruise control. i found that this issue is the same as nhtsa item # 10023585 for most similar gm vehicles, but for some reason, this family of gm trucks was not included in the reported issue. when the vehicle is stopped, the speedometer needle drops well below 0 and then jumps around when the vehicle starts moving. based on checks with our gps, the speedometer is off by as much as 20 mph. *tr

This vehicle had been parked in the driveway from 7:45 pm, (august 10, 2011). i was awakened at approx. 3:55 am on 8-10-2011 by hearing a muffled boom. at 4:00 am (aug. 11, 2011) i heard a loud bang type noise. i immediately got up and went to investigate. i went outside and found my 2004 trailblazer (ext) on fire from the engine bay and just beginning to flame inside the vehicle's passenger compartment at the dashboard..it only took minutes before the vehicle was fully involved. the fire began in the engine bay. the fire marshall report is still pending and i was informed it would take 6 to 8 weeks before it was available. approx. two to three months prior, i took the vehicle to a repair garage to fix the low beam headlights (they had failed and changing the bulbs was no help. it turned out that it was a failed relay, which was replaced. it was a couple of weeks later that i had to replace the vehicle's battery as it had gone dead and would not take a charge. the old battery was about three years old. there were no other battery/headlight issues after these repairs. no tools or other parts were dropped into the engine bay, or left in the bay. i was an aircraft mechanic and old habits of keeping rack of my tools never die and all tools used were accounted for. the roads were dry where it was driven there was no rain at the house all night. i reported this to chevrolet that day. as a result of the fire, the eaves of the house over the garage caught fire, my wife, son and myself had minor carbon monoxide poisoning, my work truck was damaged by the heat of the fire, so i cannot work (self employed) until i get a replacement (no rental company will let me use a truck to work from as i need to carry large quantities of chlorine in my pressure cleaning business. there have been no other problems of this kind before with this vehicle. *tr

Speedometer goes completely out, falling below zero while traveling on road, typically after cruise control has been used, multiple warning lights flash while onstar and computer showing no codes after 4x4 used. unable to diagnose problems because problem is intermittent and after vehicle parked for several hours problem is gone. occurs about once a week. has caused several instances of being unable to determine how fast your traveling. 2004 chevy trailblazer ext lt 4x4 i6 engine. *tr

2004 chevy trailblazer dash cluster. i have 43,000 miles on my vehicle and the dash gauges went out. they started to work after about 10 minutes of driving and now they come on only about 1 out of 4 trips. i searched the internet and found a lot of owners complaining about the same problem. why is this not a recall? please help if you can. *tr

Instrument cluster failure starting with tachometer then speedometer. at 90,000 +/- miles always have intermittent / obviously wrong info from tachometer (usually past 7000) and speedometer (always reads <20 mph). *tr

I am having multiple instrument cluster problems on my 2004 chevy trailblazer. they have done recalls on every type of chevy truck but the trailblazer. why not the trailblazer as well? i have been reading forums after forums and complaints about the same thing and gm refuses to do anything about it. this needs fixed otherwise there may be fatal accidents by engines blowing up from the oil psi gauge not working properly and so on. *tr

My 2004 chevy trailblazer has an instrument panel that stopped working. i feel this is very unsafe because i don't know how fast i am going, what my oil pressure is, the temperature of my car, or how much gas i have. i contacted a repair shop but it is over $1000 to replace the panel and there is no guarantee that this won't happen again. apparently i am being told this is a problem that is very common in this year and make but there is not a recall for it. i don't understand why. *tr

The speedometer on my 2004 chevy trailblazer ext operates incorrectly. the speed indicator sticks, goes over 120 miles an hour and stays there, and sometimes does not move at all. this is an everyday problem. *tr

1, normal driving before failure. 2. the speedometer is entirely inaccurate even in park. 3. nothing has been done or can be done to fix. *tr

My vehicle is currently at 116,000 miles and the speedometer and tachometer all of a sudden went to zero. it continued to stay at zero after i turned the vehicle off. the next time i drove it, it stayed at zero until halfway through my drive when now its stuck at 61 mph, which is where my cruise control was set. the tach now works half the time but the speedometer is giving me misleading information. i live in wisconsin where the weather is such a variable. i am always using my speedometer in certain road conditions. i have certain speeds i go in certain conditions (light snow, deeper snow, rain to freezing rain, freezing rain, slushy conditions, ice, sleet and just plain normal.) consequences for not retaining the correct speeds in certain conditions in wisconsin....gee let me think....death would probably be the worst. nothing's been done to fix this yet because i cannot afford it. it's one of those things that should just work and its a [xxx] shame gm hasn't done anything yet considering all the problems. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

My speedometer has stopped working on my 2004 chevy trailblazer. half the time it sits on 0 the other half it goes 120mph. i never have a clue how fast i am going. *tr

1. fuel tank failure, with gas smell after fill up. 2. speedometer stopped working 3. temperature gage stopped working

Instrument cluster panel issue with tachometer actually exceeding 7000rpm while vehicle is idling. i did a quick search online and found that there have been many complaints about the cluster panel malfunctioning. it was recommended that i file via nhtsa to see what may be able to be done or if there was already a formal recall on this particular defect. i have tried removing the cluster panel fuse from the fuse box then starting vehicle then turning vehicle off and replacing the fuse to recalibrate it. my understanding from the research is that the stepper motors used in the panel are faulty. *tr

We currently own three chevrolet trailblazers - 2004, 2005, 2006. on each on the three trailblazers, the dashboard instruments have failed, including the speedometer, oil pressure gage, fuel gage, and engine rpm instrument. the driver no longer has the ability to verify how fast the vehicle is traveling, or potential problems with the engine, or the remaining fuel in the gas tank. in taking the vehicles to the dealer, they insist that it will be a significant repair requiring diagnosis and removal of the entire dashboard cluster and estimate the costs to be well over $1500 for the repair. since the same problem has occurred on all three of our currently owned trailblazers, this suggests a manufacturers defect with the entire dashboard cluster. *tr

Speedometer was reading 90mph on a trip and cars were passing me, when i stopped the speedometer read 35mph standing still. it did this for about 3 days, then went back to normal. the other day coming home from a trip it seemed like it was acting up again, but my husband was driving, he thought it was acting up too. it is back to normal, haven't done anything about it. *tr

My 2004 chevy trailblazer has multiple lights on -brakes, airbag,battery, service engine soon. all the gauges on the right-oil, gas, battery are below the red line as if the car is off. the car locked itself with the keys in it while it was turned off-had to call emergency road service to unlock. the mechanic states all the lights that are on are actually functioning and that the dashboard cluster module is causing the problem. this is a major safety issue and it appears multiple people have had the same type problem with trailblazers-why hasn't there been a recall re: this issue? *tr

Check engine light - for over one year now, and 4 various mechanics, no once can figure out why my check engine light comes on. i have replaced two air sensors (actually 3 - one was bad)... i have spent close to $1,000 to get this fixed - but the dam light continues to go on (intermittently) sometimes it's on for a month - off a day - on two weeks - there is no pattern. the last time the light came on, my car began stalling in traffic and stop signs. last mechanic spent 5 hours tracing all the codes back - nothing. next day had another mechanic check codes and the engine running cool as well as a few others showed up. if no one can figure this out - where is the recourse. i feel like i am being scammed over and over. i stalled on rt. 24 slowing down in traffic - and was almost hit by a box truck because i just sat there. who can help direct me to a repair which will ultimately end this issue? now, the lights off this week (watch, now that i say this it will come back on). the only thing i notice is that many times the light turned off after i filled the tank. so, is there anyone out there who knows what's wrong (referring to mechanics who take us for a ride $$$)? i challenge anyone out there to figure this out. *tr

My chevy trailblazer displayed a service engine light and 4 wheel drive service light a few days ago. got it to the dealer. they stated the thermostat and 4 wheel drive switch needed replaced. ($550.00). the day this was replaced, i drove it home and tested the 4 wheel drive switch. as soon as i pressed on the gas in 4 wheel drive, the tach shot to 5000. it displayed 5000 for the rest of the day (even while idling). the next day, the tach stopped working all together. dealer won't take responsibility for any error or reasoning to why it quit working. just a coincidence????? *tr

I have a 2004 chevrolet trailblazer. for the past year the speedometer has run amok. i can be traveling at 30, 50, etc. mph and the needle ranges from 20 mph over the speed limit and at times surpassed the 120 mph mark on the dial. can you help? thanks. *tr

The instrument cluster stopped working, only the temp gauge and the fuel gauge works. the speedometer, tachometer, oil pressure gauges do not work. i believe general motors needs to issue a recall on this as this is a common problem with these vehicles. *kb

Electrical - all gauges are not working and the speedometer quits working while driving. *tr

The speedometer in my 2004 chevy trailblazer ext completely stopped working about 6 months about. we have been dealing with this issue and just praying we do not get a speeding ticket. now the check engine light continues to stay on even when reset. i am not being told i need to check the fuse which was unsuccessful. i can only imagine if the next thing to go will be all the electronics in the dashboard. this seriously needs to be a recall item! *tr

My check engine light started coming on and staying on; then my oil gauge started going wacky, from one end to the other; next, my gas gauge wasn't reading correctly and i had to keep putting gas in the car just to make sure i didn't run out because you couldn't trust the gauge. the gauges often correct themselves out of the blue and then they start messing up again with no warning. today, my speedometer read 0 while i was driving about 40 mph. it stayed at 0 until i stopped at a traffic light. when i took off, it went up to about 45 when i was only going about 25-30. i have no idea how fast i am really going, which is scary and dangerous. i am also very frazzled by all the gauges reading different every day when i am driving 40 miles back and forth to work wondering if and when my car is going to break down on the highway or in heavy traffic. *tr

Instrument panel/ speedometer no longer works, first incident happened march of 2010. as of 12/2013 the voltage meter, rpm gauge, speedometer have completely stopped working. *tr

I own a 2004 chevy trailblazer that i purchased new in 2004. in 2007, the instrument cluster began to malfunction exhibiting erratic function. i took it to my local dealer where i purchased the vehicle and it was replaced under the warranty. now, here it is, 2/2010 and the cluster is doing the very same thing the original defective cluster was doing. i have gone online and read where many, many owners of chevy products from 2003 on are having these comparable issues and that chevy has some sort of extended warranty they are offering for many gm products with these defective clusters. i am disgusted by the fact that, from what i have read online, trailblazer owners have been excluded from this extended warranty due to an inadequate number of complaints necessary to warrant coverage. it is a known fact that the trailblazer has the identical instrument cluster as the other gm products covered in their extended warranty. at this point, i am adding myself to what i'm sure is a growing number of unhappy gm owners coming to you in hopes that gm will be made held responsible to replace a their defective product. *tr

I also just had to replace the cluster for my instrument panel in my 2004 chevrolet trailblazer. i find it very interesting, the number of cars that are having the same failure as i have had at approximately the same time. *tr

On 02/05 /2010 i was going south on 165 to monroe, la it was about 8:00 at night,when the dashboard lights then the headlights just went out. this made me go into a panic. i did not know what to do because it was very dark. i did manage to pull over. thankfully there was a gas station near by. on 2/06/2010 i took to a chevy dealer and they told me that they have be seeing this problem for some time. but they close early on saturday so they could not fits it in one day. so i took to another repair shop and they told me they have seen this same problem 4 times in jan. so chevrolet has a problem that needs looking into. *tr

The speedometer, oil pressure gauge, and tachometer have stopped working on my 04 trailblazer. only have 64,000 miles on it. have talked to mechanics about replacing. told it would cost between $400 and $800 to replace but may not fix the problem in the long term--many times replaced clusters have the same problem. look at the internet and you will see that many people are having the same problem. *tr

I was drving down the road and the speedometer stopped working while the truck was in motion. it went from 60 mph to the needle going all the way past 120 and pointing down at the odometer. my speed did not change during all this. *tr

I have a 2004 chevy extended trailblazer with 84,000 miles. my speedometer is stuck at 90 mph. i understand it is not a recall issue and this is not covered under my warranty. it will be approximately $500 to fix a safety issue. i don't feel this is fair. it should be a recall. it is a safety issue when you don't know what rate of speed you are traveling. i understand from discussion boards in the internet that this is a very common chevy trailblazer problem. i have not yet had it fixed as i cannot afford it at this time. my car was just in a few weeks ago for a cost of over $300 for a thermostat. tw*

My 2004 chevy trailblazer oil, gas, speedometer and battery gauges stopped working and my heated seats smell like they're burning when turned on. *tr

All gauges are randomly failing, but even when working they do not read properly. the speedometer will read all over the place and not move and then at times appear to work, but thanks to a gps in the car i noticed it was showing 10 to 20 mph off on the low side. *tr

The speedometer and battery guage will not work. the speedometer shows over 100 mph when you are not moving. called the dealership and they said they get calls everyday on this problem, but gm does not have a recall on the trailblazer only on the pickup trucks.

The rpm gauge, battery gauge and the fuel gauge stopped working. first the rpm gauge stopped and then about a year later the battery gauge stopped and last was the fuel gauge that stopped. the fuel gauge stopped working just a couple of weeks after the battery gauge. i am also having problems with the daytime running lights not staying on periodically. the daytime running lights will go out about twice a year and mainly at night. *kb

There have not been any accidents or injuries yet, that i know of. there have, however, been many complaints that i have seen for the same problem i am having and chevy does not care. the speedometer and other gauges on my 2004 trailblazer do not work correctly, the speedometer can read 0-120 when at a complete stop. therefore we never know how fast we are going and with children in the vehicle this is very disturbing. besides the gauges the wires for the headlights keep burning. i was told when i had the first one fixed that it is very common in these vehicles. the fact that both of these problems are so common with many chevy vehicles and they are recalling some and not all, i guess i just want to know why not all? *cn
