Pontiac Grand Prix heater problem
I recently bought a 2000 grand prix se. The heater would only work on high (im guessing blower motor resistor. My dad was driving it down the interstate after work the other day with the heater on when all of a sudden smoke blew out through the vents and the blower motor stopped working completely. It no longer pushes air. I ran cables straight from the battery to the blower motor and it spins fine like that plus I also went down and bought a new blower motor ($75), hooked it up and still nothing. I bought a heavy duty circuit tester and im gonna try to probe the pigtail for the blower motor, and im also going to try to probe the motor blower resistor plug. Is their anything else i can try to attempt to figure out what the problem can be? Does anyone have any other ideas of what it could be? I wasnt in the car at the time so i cant really say if it smelt anything like anti freeze. Any help would be appreciated as it is starting to get bad out with the cold rolling in. Plus driving to work at 4 am with the windows fogging up is not the best thing to be doing. thanks ahead of time.
