Having problems with your 2002 GMC Envoy ?
My air conditioner fan speeds have all stopped working except for 5. Any ideas what is causing this? The vehicle is a 2002 GMC Envoy.
Yes,it is the blower resister,it controls all the speeds to the blower motor,it is located near the blower motor,and it might have a wire harness that is burned up too,replace it,and the wire harness,and the blower motor,the blower motor is what causes the resister to fail,it draws too many amps,even though it might sound good,and run fine,it is requiring to many amps to run it.If this was at all helpful,please rate,thank you.
