Pontiac Repair: Heater blower motor runs all the time, blower motor resistor, gmc yukon

Question
Hi,
I have a 2003 GMC Yukon. The last time I started it the front heater motor would not shut off even when I turned the key off. Heater works fine but blower is always on.
Thanks for any assistance.
Roger

Answer
Hi
I would HIGHLY suspect the blower motor resistor.
It is located right next to blower motor, under passanger side dash. (Under glove box)
It MAY also need the wire harness, they are VERY, VERY common for melting circuits.
I Hope this helps
Good Luck
