Question about 2002 GMC Envoy
I have no air flow,heat or ac,the switch does not work, I checked the fuses, power to the blower motor and the blower motor and they work???
Last place to look is the resistor block located in the duct work for the blower (fan). it should have a wiring plug going to it and be held in by a couple screws. look on the passenger side near the fan itself.
