Wiring problems of the 2007 Chevrolet Silverado 1500

Bundled wiring under dash started smoldering while vehicle was parked in driveway, had been sitting for about 48 hours. I pulled much of the dash apart to make sure there wasn't an active fire. While being repaired at local chevy dealer. Wiring actually caught fire burning the repair techs hands. When I asked what could have caused this, they just told me that sometimes it happens and they don't know why.

While driving at any speed would roll down window and head lights would dim. Blower for heater and defroster would cut in and out. There was a distinct odor when using defroster and then it quit all together. This was during winter which made the truck un-drivable until repaired. 10-14 day after the blower motor was replaced the oil sending unit stopped working and all warning lights were lite up. The dealer ship stated that it was a know issue with the wiring harness and needed to be replaced which was not cheap. They did say even though it is a know issue that we were responsible for the cost of repair.

The a/c fan quit. It smelled like burning plastic. Luckily I was able to exit the freeway safely and I have enough electrical knowledge I was able to determine a way to continue safely. It was a fire hazard waiting to happen inside the cab. The resistor was extremely hot and the wiring harness was melted. There were no blown fuses. I pulled fuses to reduce the chance of fire. I have previously attempted to deal with the Chevrolet dealer nearest dfw, TX airport and gm over my bad engine block (also reported on this forum) and . . . . . . . . So I am out the money for this fire hazard too. This is the last gm product I will ever own.

1 avg. Use of heat and a/c 2 melted wiring harness to blower motor 3 nothing done by gm.

The contact owns a 2007 Chevrolet Silverado 1500. While driving approximately 30 mph on normal road conditions, the seat belt retractor housing unit exploded unexpectedly. The failure caused a loud popping noise during the explosion. Immediately, the driver pulled over into a parking lot to inspect the vehicle. Onstar customer service responded with an indication of a front end crash; however, there was no crash and the air bags did not deploy. The air bag warning indicator illuminated on the instrument panel and remained lit until the engine was turned off. The contact took the vehicle to the dealer for diagnostic testing and they stated that the failure was related to corrosion in the wiring system. The parts for the repair were unavailable and the vehicle has not been repaired. The VIN and mileages were unknown.
