While driving I noticed a burning smell outside of my vehicle but assumed it was coming from the area around me not my car. When I got to my destination I noticed smoke coming from under the left side of the hood and above the drivers side tire. I raised my hood and noticed smoke coming from around my fuse box. I had the car towed and have been told by my mechanic my fuse box and wiring harness burned. He also stated there could be other damaged related to this fire. The mechanic also asked if I had problems out of my headlights because the problem seemed to have started with the headlights. I have researched this since being given this information and electrical problems seem have been a problem with Trailblazers. I found several instances on this site and also online related to electrical problems on the Trailblazers. Complaint #10487846 is identical to mine and its ashame nothing gets done about these mechanical failures until there is a tragedy.

Above date & mileage is approximate. I am only able to activate driver's side window. No other windows operate from driver's door panel. I was told that there was a recall, but I never received any information about the recall. I have owned the car since around 2004.

When driving the check gauges light illuminated and the oil pressure gauge was at zero. This occurred when I slowed and then stopped at a traffic light after having driven for about 20 minutes (the vehicle sounded as if it were about to turn off so I pulled over and turned it off). When looking at the instrumentation panel I then noticed the check battery light is dimly illuminated (battery is 6 mo old) and various readings are off (rpg is registering low and one RPM indicator starts at 5 when the ignition is turned on). Various Trailblazer forums are indicating owners are experiencing the same problem. Two Chevrolet dealerships have indicated that it is likely an instrumentation cluster problem (and indicate they have guidance from GM to run 2 checks to determine if it is an instrumentation cluster problem). Two independent repair shops have identified it as an instrumentation cluster problem that they have seen on many 2002 Trailblazers. The repair costs range as high as $750. GM customer assistance can only state this is not a recalled repair (applies to later models but not 2002); therefore, it is the customer's responsibility. My GM file # is [xxx]. GM did ask that I pay $80 for the diagnostics, while also saying they would not pay for the repairs. Adding an additional $80 to costs or paying a dealership more money than an independent shop is not practical nor an added expense I should assume. Most amazing is that GM can give dealerships instructions on diagnosing this problem, dealerships are repairing a far amount of vehicles with this problem, independent repair shops are aware of this problem because of the many customers who patronize them, yet GM takes no responsibility for correcting this known problem..this is dangerous, the car can stall anywhere and lead to an accident without customers having any idea of the problem.

The vehicle was not taken to the dealer. The manufacturer was made aware of the failure but did not offer any assistance since the vehicle was not included in any recalls. The vehicle was not repaired. The failure mileage was 160,000 and the current mileage was 171,000.

In June 2010 the overhead dvd player quit working and the bose in-dash stereo systems began to intermittently work and not work. In May 2012 the windshield wipers would sometimes not turn on and at times in operation would stop operating mid way. At the same time, the bright lights sometimes would not come on. Moving the steering column up and down would allow the brights to operate, but in most cases they don't work at all. The heat & A/C fan motor only works on high speed as well leaving the other speeds inoperative. It seems there may be an electrical issue in the steering column and I'm not sure if the stereo and dvd player would be somehow connected with that portion of the wiring harness. I contacted Chevrolet and they say there are no open recalls for our VIN number.

I have had multiple issues with my 2002 Chevy Trailblazer where the 4X4 selector switch will not work, or while driving at highway speeds the vehicle will be put into four wheel drive while the selector switch is still turned on two wheel drive. The selector switch at times has not worked when I wanted to make the vehicle go into four wheel drive. I have found out the vehicle is in four wheel drive by having a hard time turning the front wheels and seeing the front tires spin on loose gravel even though I never switched the vehicle into four wheel drive and the selector switch states it's still in two wheel drive but the yellow light is lit up that it's in four wheel drive. I have complained multiple times to GM and have had the selector switch replaced 3 times but it still continues to happen. Everytime that GM looks at it they say that it is working just fine. I have seen and heard that many other people are having the same problems with this. I feel there should be a safety recall put out for this drive selector switch.

I feel that even if you have had a recall issue once and the situation continues to happen then it needs to be fixed until the problem is solved I have contact GM several time and nothing has been done to ratify my problem with the windshield wipers and the 4 wheel drive and several other recall issues this is sad I say we need a class action law suit I am not one to take legal action but for people that have this kind of money and to not fix their problem that they put out on the roads for us to drive safely is shameful.

My 2002 Trailblazer 4X4 came locked up completely with no possibility to even open door with the key. Chevy dealer blamed the module vcm located under the behind seat that must be changed. Re-programming all seems working but erratically until the effective change of vcm module. Is there a possibility to repair it ? thanks [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The rear right and left brake lights and rear turn signal lights have burned out repeated. I purchased the 2002 Chevrolet Trailblazer in December 2001. The problem first started to occur when the brake lights failed at 30,000 miles in 2003. I had to replace the circuit boards the lights plug into at my own cost to fix the problem. There was a recall to replace the circuit boards in 2004, NHTSA #04V527000, which I had performed on the vehicle. Subsequently the circuit boards burned out again a few years later. I took the vehicle back to the dealership and they said they wouldn't replace the circuit boards at their expense. I then purchased and installed the circuit boards myself. In 2010 the circuit boards burned out again. I took the vehicle back to the dealership and they investigated and said they couldn't find anything wrong with the vehicle other than the circuit board. They charged me $191.50 to investigate the problem and change out the circuit boards again. This is a safety issue because the rear brake lights and rear turn signal lights not working increases the risk of a crash. I received a ticket/warning on 2-2-11 for the brake lights not working but expect the brake lights will become inoperative again soon as this is the 5th set of circuit boards that have been placed in the vehicle and they keep burning out, and Chevrolet/General Motors hasn't supplied a satisfactory correction to solve the problem. Current mileage is 159,000 and the problem started at 30,000.

Chevy 2002 TB lt/4WD - multiple electrical problems since purchased (used 3/2010). Started with rear ww non-function which Chevy dealer charged $1500 to repair, claiming it was bad body wiring harness and it was not an uncommon problem but Chevy would not take any responsibility. After repair, other electrical issues have popped up from things as simple as outdoor temperature gauge not working, passenger window won't roll up/down (though motor is fine) as well as pass electric doorlock and mirror nonfunctioning. Larger occurring issues which could effect safety include the vehicle randomly deciding to change from 2wd/A4wd/4wdh4wdl whenever it wants to under various weather/road conditions (including perfect weather and road surface) and occasional random ignition system failure. Otherwise great vehicle with seemingly normal wear and tear problems but Chevrolet's refusal to acknowledge responsibility and provide repair is disgraceful, irresponsible and dangerous.

My headlights started to flicker one seasonably winter day. I had the heater motor replaced 2 months prior to this incident and back wiper motor just a month before this.then the heater motor cut out, and did so numerous times as I traveled on a 20 degree day. It seemed to run fine after that for the most part that day. I later got into it and again headlights flickered and heater motor cut out. Especially when I would accelerate or turn to the right. I replaced the battery, alternator and had ground wires cleaned only to have it recur a week later. I do most of my driving at night and when the lights went out and came back on I had enough. This had become quite costly and my mechanic was at a loss as to what to do next. I took it to a Chevy dealer and traded it in on another vehicle, as I can no longer afford to keep spending money on a mystery issue.

First the left side of my temperature control lighting went out, a week later I got a steady service engine soon light, it then went out after a few minutes, it then stayed steady for a period of 2 days, then went out. Then 3 days later my indicator light above my 4-wheel drive control went out, I attempted to change the fuse, then got a service four-wheel drive warning.
