Have had multiple problems with no brake lights, hazard lights or driving lights. Vehicle also has been in two front end collisions and air bags did not deploy in either wreck. Vehicle was looked at by a dealer and could not be fixed.

Shortly after adjusting the front passenger power seat control I noted a trail of smoke from beneath the seat and the smell of burning plastic. I immediately opened the fuse panel and attempted to remove the main fuse. The upper main buss that controls the power seat motors, power doors, and anti-theft system was so hot that I could not touch it without burning my fingers. I had to use a pen knife to remove it. No other fuses were affected. Following removal of the fuse my turn signals, emergency flashers, and rear stop lights are all inoperative. These elements are on a separate circuit from the main buss I removed. I believe that had I not gotten the fuse removed when I did the electrical short would have resulted in a serious fire.

Power accessory circuit breaker (20) gets extremely hot after power windows and power seat fails to operate. At same time, when hit a bump in road, interior lights flicker. Burned fingers trying to remove breaker before fire may have started. Dealer guessed and replaced driver seat electric switch, but still gets hot and fails.

Brake lights came on and would not go out until the brake light fuse blew out. Replaced fuse and brake lights would not go out. This happened about 2-3 months ago and I took this vehicle to jones Chevrolet in sumter, SC. They said they adjusted the brake light switch and corrected the problem. This time I took the vehicle to tim's auto pro in dalzell, SC to get it checked out. Tim found that the wiring from the fuse block up under and behind the dash had shorted out due to the way it was installed originally at the factory. Part of the wiring harness was chaffed in several places and the wiring melted together keeping our brake lights on. He removed the dash and associated items to get to the harness and repaired it so our brakes work and there are no shorts. My concern is that GMC should be paying for this repair since the harness was not installed properly when the vehicle was built. If by some chance the wiring had caught fire under the dash while my wife was driving her GMC Jimmy down the road there could have been serious complications or loss of life. Please check for me with GMC and see if this is a problem that has been reported on other GMC Jimmy or Blazer products.
