Hey everyone, Im havin a little problem with my blower motor. It seems to stay running at low speed even when the ignition and accesory is off and kills the battery overnight. I have no idea where to even start with this problem. Also the fan seems to only have a low speed and only comes out of the floor vents. Im guessin' the switch in the dash is shot, but any other educated guesses will be more than appreciated before i get tthe hammer out. Thanks.

Hello: What year car do you have??? For sure the blower running with Ign off is not a good thing. What year car and possibly can scare up a schematic and give you a hand with your problem. Is car stock or has a wiring maniac been at it
good luck
