Wiring problems of the 2002 Chevrolet Trailblazer

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.

The headlight wiring inside of the lens assembly over heats and melts the electrical connector going to the bulb and the insulation on the wiring. This has happened to both headlights on more than one occasion. Had to go and have the electrical wiring plus connector replaced.

The contact owns a 2002 Chevrolet Trailblazer. The contact stated that the headlights did not automatically turn off when he exited the vehicle and smoke was emitted from under the hood. Upon inspection, it was found that the fuse box was smoking and the wiring harness had burned. The vehicle was towed to a private mechanic. The vehicle was not repaired. The manufacturer was contacted about the failure. The failure and current mileage was 169,000.

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 occuring 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, irresposible and dangerous.

The contact owns a 2002 Chevrolet Trailblazer. The contact stated that the key fob sensor failed to open the power doors. This presents a hazard because there is no manual key entry for the doors. The failure occurs in cold weather conditions. The dealer stated that the repair was under warranty and will be repaired. They will replace the sensor and check the wiring in the vehicle. The failure mileage was 39,200 and current mileage was 39,620. Updated 03/09/09. The rear wiper was inopertive. Updated 03/12/09.

The contact owns a 2002 Chevrolet Trailblazer. The dashboard panel illuminated intermittently. The failure prevented the dashboard from displaying the speedometer and tachometer. Occasionally, the tachometer and speedometer displayed incorrect speeds. The dealer stated that the vehicle needed an instrument panel cluster, and mentioned recall # 03v096000 for the electrical system: wiring: interior/under dash. Although this vehicle was excluded from the recall, the contact did not feel obligated to pay for the repairs since general motors was aware of the recall. The current mileage was 72,449 , and failure mileage was 71,000.

2002 Chevrolet Trailblazer left low beam bulb stopped functioning. When I replaced it I found that the connector was black and melted. The replacement connector was significantly more robust.

: the contact stated the instrument panel was inoperable. There was a NHTSA recall, #03v096000, regarding the electrical; wiring; interior/under dash. The vehicle was not included in the recall due to the VIN.

I was going down the highway. I stopped at a gas station for a cup of coffee with my sister and 3 year old daughter. When I went to put my daughter in the car I noticed smoke coming up from under the plastic part in the back seat on the door part. I saw something spark and took the casing off and then it sparked again and it flamed some everytime I blow it out it would spark again. I got the wires off the metal from the door and the one wire came apart. The plastic that is covering the wires was melted off and the tape that was over that was also melted off. I took it to the dealer in nazareth PA to get it looked at. They had to replace 4 wires and 3 fuses. It cost me $100. 00 to fix. Gm called me and said there was nothing they could do because I already had it fixed and that they said it was not that serious. I told him that if I didn't go get coffee and didn't notice the smoke it could have been worse then it was and that my 3 year old daughter was in the back seat. He said he was sorry but there was nothing that he could do and he was glad no one was hurt. The person that I talked to was joe garcia # 8667905700 ext. 21260 case # 1-415496321. It is not about the money having it fixed it was the point that they said it was nothing.

I have a 2002 chevy Trailblazer. My inside lights have stopped working and I assumed that is was due to a blown fuse. I took it to the chevy dealer ship and they stated that I may have a wiring problem. The wire the connects to my headlight burns out easily and my bulbs for my taillight has to be replaced often. Can you please assist. I have to replace the head light wiring several time and have to replace the tail light bulbs. The problem started several years ago. The last time that I had to replace a part was December of 2009.

The radio randomly changes station while driving, sometimes repeatedly. Often it appears that this is related to turning as if something in the steering column is affecting this. This function is distracting to the driver.

Two years ago the liftgate when closing would not lock and remote lock key fob failed to work. Dashlight indicated that tailgate was ajar and dome lights remained on. In the last year the controls on the driver' s door quit working. The power locks, windows, and side mirror controls did not work. Rear defroster will not work. No parts have been replaced because dealerships will not do it for free. I could not afford to fix this problem. Very frustrating. . . . . First new vehicle, and it will be my one and only Chevrolet. I will no longer purchase from gm due to their lack of willingness to fix a problem that they were aware existed in many vehicles.

The consumer's 2002 Chevrolet Trailblazer caught on fire two hours after the vehicle was parked. The consumer had complained about the steering wheel and the buttons being hot. The fire started in the front of the vehicle. The consumer believed that there was a wiring problem in the steering wheel where the cruise control, radio and other buttons were.

2002 Trailblazer acted like transmission going out, took to dealer they upgraded computer. Front right low beam wired burned and melted, took to dealer they wanted to charge 250. 00 plus labor for light assembly when all it needed was a piggy plug, bought plug at napa and fixed myself. Never have had two back lights working at same time. . . Cant take to dealer to get the recall work because it seems that these vehicles are using a "weak" oil pump and my Trailblazer has been in shop for last month or more waiting to be fixed. The weak oil pump caused damage to rod bearings, main bearings, and crankshaft. Gm says out of warranty and my customer service specialist said "I'm sorry" about 10 times but she was still closing my folder and marking dissatisfied. She can't help me because I'm out of warranty. I hate this vehicle. I have found quite a few recalls but can't do most because its in the shop. I never got any recall notices.

Right low beam headlight shorted and brief fire within headlamp.

We have been having problems with the brake lights not working on our 2002 chevy trail blazer. We have been told from the dealership that we bought our vehicle from that there is no recall on this issue and that they are aware of problems with other Trailblazers with the same problem. We have been told that we have to buy new plates that hold the tail lights that put out lower power to the bulbs. The current plates that hold the brake lights constantly burn the cotacts in the bulbs. I have been told by the dealership that the new bulb holder plates are $70. 00 each plus the labor. To me having no brake lights is a major safety hazard and you usually do not know when they are out unless you are notified by someone or you are pulled over by the police. We have also had similiar problems with the headlights but they last about a year before they need replaced. So much for quality in our craftsman ship for our american made vehicles.

The vehicle repeatedly switches into a 4 wheel drive (4wd) and 4wd modes on its own during normal 2wd operation. The dealer claims that the onboard computer recorded no such occurrences, and therefore is ignoring the problem. Numerous similar complaints filed on this NHTSA web site indicate that this is a widespread problem with the Trailblazer which mere replacement of the 2wd/4wd switcher module will not remedy. This fact--taken along with frequently burning out bulbs (running lights as well as brake lights)--suggest that a possible larger yet more fundamental electrical wiring problem is what's plaguing an otherwise excellent vehicle. This is truly a shame.

The windshield wipers were inoperative, the instrument panel lights were flicking on and off, the inside dome light would not come on. Updated 04/13/15. Updated 07/20/15.

There is a malfunction in electricial system wiring causing all back lights to go out without wear. . Problem happened numerous times. Dealership replaced fuses, wiring, etc. . Problem still occurring.

I have a 2002 Chevrolet Trailblazer and the electric mirrors are erratic - they won't hold their memory. I understand this is a big problem with Trailblazers. When you start car you do think to check mirrors everytime and it can be dangerous when you go to change lanes and realize that the mirrors have lots their memory. I have almost had numerous accidents due to this defect. I feel it should be a recall for Trailblazers as this problem has been reported by a significant amount of trailbazer owners.
