What is the cause of a 2002 Chevy trail blazer's heating blower not working?
Blower motor NG.
Blower motor resister NG.
Blower motor fuse NG.
Blower motor switch NG.
What would cause intermittent problems with blower motor on 1998 Chevy blazer sometimes it gets power sometimes it doesnt. it quits working while on or starts working while on. also wheres the relay?
If you are missing some or all low speeds on the blower motor but still have high speed that would be the resister. The resister is located under the hood, attached to the HVAC (heating, ventilation and ac) box close to the blower motor. It has a removable electrical plug attached to it and is held in place with two small screws.
