Tl-the contact owns a 2007 GMC Sierra. The contact stated that the heater failed. The motor would operate but no heat would emit from the vents.

Heater motor continues to run after the switch is turned off, the blower only works randomly. I under stand there is a recall for this issue but my VIN is not included. This seems to be a problem in a number of different gm vichicles. There is a chance of electrical fire with the being able to run with the switch off also the report would not pull a list of parts nor would it permit me to type in the parts: heater motor blower resistor, and wiring connectors.
The wire that connects the airbag "person in the seat" switch breaks when you put (slide) the seat all the way back. They know this and have not recalled the truck! they will not and are not going to pay to fix it. The airbag will not deploy when needed, is this a safety recall?.
