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 blower for the back of the vehicle is stuck on and is blowing hot air. It will not turn off and it won't blow cold air. Also, The blower level 5 in the front part stopped working. The air conditioning is not working in the front either.

Blower would stop blowing, sometimes worked and sometimes didnt. Ordered the part on line and it was not what they said it was and charged me shipping and restock fee. Went to my local o'riley's and they had the part in stockband for cheaper.
