Wiring problems of the 2004 Chevrolet Trailblazer

Oil pressure gauge drops to zero causing "check gauges" light to come on and engine to stall when the a/c is running and am stopped at a light in the city. This only occurs once during a trip or once a month. Understand that Trailblazers have a history of gauge problems and electrical issues. Chevrolet needs to issue a recall for electrical wiring/gauges.

The contact owned a 2004 Chevrolet Trailblazer. After plugging in a tire inflator into the cigarette lighter port, the vehicle filled with black smoke. In addition, the contact smelled a burning odor. The contact immediately removed the tire inflator from the port and shut the engine off which stopped the vehicle from smoking. The vehicle was towed to a dealer where it was diagnosed that the fuse box, wiring harness, and various other internal components melted. The vehicle was destroyed. The manufacturer was not made aware of the failure. The failure mileage was 155,000.

I parked the car in my driveway and the passenger side mirror started clicking. The mirror was attempting to rotate to the extreme car side of the mirror. Using the remote mirror control had no effect. The car was turned off and the mirror motor continued to try to move the mirror past the limit. After several minutes, the clicking stopped and there was an odor of plastic burning. After the clicking stopped, neither mirror moved. The local mechanic said the wiring to the motor had burned and shorted the mechanism. I was lucky that there was no damage to the interior of the door. Has this malfunction been a problem with the Trailblazers?.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that after starting the vehicle, the driver's side window switch failed. The vehicle was taken to an independent mechanic for diagnosis where it was advised that the switch wiring caught fire and burned. The vehicle was not repaired. The manufacturer was notified. The approximate failure mileage was 80,000.

I started to lose the high speeds on the fan blower. In checking the internet I found this is a common problem for g. M. The problem is the blower motor resistor. When I went to replace this part I found that the whole wiring harness had been burnt to. It got so hot that it melted everything. The fuse for this did not even blow. This could have set the truck on fire. It is funny how the parts to fix this has much thicker wire. The parts in total was around $118. Thanks to a friend I had no labor cost. If I would of taken it to a g. M. Dealer for sure they would of wanted over $300. G. M. Knows they have a problem and are doing nothing about it. I feel this is a serious matter as it could of set the truck on fire.

All within the last few months I have had to replace the complete drivers side low beam headlight and electrical pigtail because it caused an electrical short that burnt the wires. A few weeks later driver's side rear stop light quit working, I had to replace the bulb, next, the blower motor won't work on 5. . . And it won't transfer from defrost to vents. . . So, I am currently replacing the blower motor resistor and the red wire is fried because it appears not to have been "pushed" all the way in from the factory, (I have taken a picture of it)and now I have to "replace" the entire wiring harness. . . I'm really starting to hate chevy. . . Especially when I browsed through all the complaints. . . Is there ever any resolve? I think most of the issues I /we have are all safety issues. . . Would you handle things differently on your end if someone you know and love was in this type situation where they were concerned for their safety as well as the public's safety!!!!.

On 8/1/06 I was awaken by a neighbor at 1 am saying my car was on fire. The fire department was called but the entire interior was destroyed. The fire department said it had to have been an electrical malfunction. The vehicle had been parked since 8 pm that night and it was locked. There was no sign of forced entry and no sign of any other reason for the fire. The car was purchased new in 10/04 and had less than 30,000 miles on it. I used the roadside warranty to have it towed to a dealer but the dealer refused to have anything to do with it. It took two weeks for gm to send a fire investigator out and their investigator said he couldn't determine the cause of the fire. I filed a complaint with the vermont state attorney's office but gm did not respond to the complaint. I had electrical repairs done just a few months after purchasing the vehicle too and the stereo system had stopped working just a month before the fire. The car is still sitting at the dealership. I did not have collision insurance because the car was paid in full and my current finances did not allow me to maintain anything more than liability insurance. So now I have no vehicle and this is tough with 3 young children. Gm refuses to honor their warranty and insists that this model vehicle doesn't have electrical issues. It's time someone made gm honor the warranty they charge for when you purchase a new vehicle.

I bought vehicle in October 2003. It is a 2004 Chevrolet Trailblazer. In the months following I began having electrical problems . Check engine light would flash on and then went off again. The first time it happened car stalled as well. I would bring it in to the dealership and they would say that they could not duplicate the problem, and they hooked up to the computer and didn't find any problems. I also had my headlights flicker when accelerating and decelerating. I have had numerous problems with my blinkers. I have had the tail light assemblies replaced twice. I recently took it again because my left blinker would flash much faster when I touched the brake. Also, if I just touched the brake the right blinker light on my console would illuminate. Also, it looked as if I had my lights on for reversing while I was driving, which was extremely unsafe as other drivers thought I was reversing when I was going forward. I have had 4wd light come on and then turn off again later. I have had my main computer replaced twice and my flasher computer replaced once. I had to have my keys reprogrammed twice and they finally found out today I had faulty electrical wiring which was supposedly causing the trouble with the brakes and flashers. I have brought it in for this problem 3 times in the last couple weeks. I also have a problem with the gas tank overflowing everything I fill up no matter what I do and I am not trying to "top off". Also, I have had several problems with my seat belts and have them replaced as well. They would lock and I would be unable to get it one to drive the car safely. I had to drive my car to the dealership with no seat belt. Overall, these problems amount to a poorly made very expensive car that leaves me feeling unsafe in my car. Please make Chevrolet listen to its consumers and pay restitution. We were all lied to by the car manufacturer, who had to have known it was producing an inferior product.

There has not been an accident yet, just one looking for a place to happen. My vehicle I believe has an electrical problem. Which in turn affect all functions of the vehicle, safety being one. I have had (2) fan switches go bad (2) crankshaft sensors go bad. (1) cruise control malfunction. (1) turn signal relay (1) radio console replaced for overheating (1) headlights when below 32 degrees flucuate in brightness till vehicle warms up. Dealer stated this is normal operation. Ha,ha, and transmission shifting problems (1)they reprogramed computer to solve, next some solinoid replaced and now the problem is back. I have a family of 6 that I have in the vehicle 90 % of time. I now have concerns that the wiring must have a short somewhere. Which potentially could cause a fire, or an accident due to what happens when the headlights go out or antilock brake system fails or taillights, etc. Gm refuses to replace wiring in vehicle. Gm rep told me to contact whoever I wanted to. They are not going to stand behind fixing the problem. Just keep replacing the electrical items as they go bad.

Shortly after I purchased a 2004 chevy Trailblazer I began to have problems with a loud vibration from the undercarriage. It has been to the shop numerous times but is still not fixed. Recently the vehicle began stalling out at any given time. Dealer could not replicate. Still does it!!! around the same time my transmission would slip. Dealer could not replicate. Still does it!!! now I am feeling a lot of vibration in the steering wheel when I turn. Talked to other tb owners and I thinking I will need to replace the struts. What next!!.
