Htg and a/c fan switch only works on high in 2004 GMC Envoy. The a/c and heat work, just the blower only blows on high


Sounds like the blower motor resistor module is bad. It is located behind the glovebox and mounted to the blower motor. Open the glovebox and in the back left corner find a spring, push on spring to release glovebox door completely. You should be able to see blower motor and resistor module.

The ac works but the switch wont turn on the fan. the rear controls work. its just the front that doesnt. checked the relay switches they seem fine.


Either you have defective blower motor or a defective blower motor resistor module. The resistor module has been known to fail on these trucks. Both items are located behind the glove box.

Gmc sierra blower switch


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.

If only some of the fan speeds work this is always the blower motor resistor located in the hvac case inside the right front of the vehicle where your passenger feet would be.the blower motor resistor is available at most larger parts places.I replace 2 or 3 of these a week. Good luck
