Loss of One or More HVAC Blower Motor Speeds on GMC Envoy

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

the ac/heat has never ever worked correctly from day one. They would only consider looking at it when the problem was occurring, so had to drive out of my way several times in the beginning to prove it to them. I had it in five times and it still blows hot air out the left side, and cold air out the drivers side and now it will only work on one setting..spin the air flow adjustment and nothing happens. This was and is more than frustrating and of course it's out of warranty now...garbage.
