One problem related to front seat heater/cooler has been reported for the 2004 GMC Envoy. The most recently reported issues are listed below.
Front passenger seat caught on fire from the seat heater. The vehicle parked and turned off. It was parked in a high school parking lot while my daughter was in school. We contacted GMC, but they said it there was nothing they could do. There was something that went wrong for it to just catch fire. Can you help us in anyway at all.
