Question about 2003 GMC Sierra
I bought the truck this spring and occasionally I have smelled burning wires. Over the last 3 weeks the blower motor has quit working on me several times. If I wiggle the pigtail connection at the resistor it will start working again until it happens again. The connection seems to be very hot. I purchased a resistor pack and replaced it and it hasn’t made any difference. It appears the pigtail requires replacement as the third connector is burnt out. I talked to the previous owner recently and she advised me she had problems with the connection at the blower motor resistor and had it replace. Is this a common problem and what is the “proper fix” for it.
