    Blower Motor/Resister Problems....?????

    Hey Mangs, I have been having trouble with the stupid blower motor on the car. its a new Blower Motor from Napa I replaced it last summer but for some reason now it was only working when it wanted but now not at all... The A.C. works fine... My brother thinks its the resister...
    BTW.. The blower Motor works when it is hooked up directly to the battery... (The Car is ATC)

    does it work on high speed but not on lower speeds, or does it not work at all? The resistor is not used at all on high speed, so if that works but nothing else does, its probably a resistor or a connection problem. If nothing works, I'd be looking at the fan switch itself.

      The fan does nothing when hooked back up to the car (ATC)... It only works when the fan itself is directly hooked up to the battery...

        the fuse is good right? 30 amp in the fuse panel, should be the only one. If thats good, but you have jack squat for life, it sounds like switch issues. The power circuit for these is odd. The blower has +12v on it all the time. The negative side runs to the switch, and then out to the various taps on the resistor to ground. On high, it just goes straight to ground. If you have a burned out switch, nothing will work. If the ground is open, it won't work either. Of course if you have no +12v supply, nothing is gonna happen. Need to figure out whether you've lost the ground or the + side of things. Grounding the black wire ought to tell you something. If the fan comes on, its something in the switch circuit or the ground. If nothing, then you most likely had a failure between the fuse and the + side of the motor. I believe that may route through the main climate control head unit, but not 100%. You've got a 90-91, and I don't know the systems on that car so well.
