Front Seat Heater/cooler problems of the 2003 GMC Envoy

Drove to work Saturday night 12/07/2013 parked car at 7:30 pm went in to work . Came out to my car at 10:00pm for break to see my car smoking the passengers heated seat turned it's self on at some point and was on fire burning the seat and my cooler that was sitting on the seat was on fire and smoke filled the car was making it hard to breath the smoke was thick and smelled toxic. Me and my fellow employees dumped snow on and under the seat from as far,away as we could till the smoke calmed down. To get the fire out. I am so grateful I was not driving or there was no person sitting on the seat at the time could of caused me to wreck myself or others. On my drive home could not use the heat due to the fumes being to strong with the windows up and heat on had to drive with no heat and windows down 40 minutes with the temps in the teens.

Consumer complained there was not enough hot air to warm up the second and third raw backs seats. Dealer and manufacturer indicated we were aware of the problem.
