i have a 2002 grand prix. my fan wont stop running and it wont come off of high. even when the ignition is killed, it wont stop. any idea whats wrong?

Sounds like a problem with the blower motor resistor, or a bad ignition switch. Disconnect your positive battery cable, so the battery doesn't go dead overnight.

Hey this happened to me once about a year ago, did you ever resolve this issue? If so what was it, cause my fan only works on 5 now and I'm wondering if they're related at all! thanks!

If it works on 5, you have two possibilities: blower motor resistor or ignition switch. The former fixed mine.

Blower motor resistor is shorted, forsure

sounds like what happens everytime i fry my PCM when i flash it


but dont worry somethings just shorted

Wait are you talking about the radiator fans?
