update: well, the fan was working now not even that is working. I think I might have fried the motor when I was hooking up the leads to test the fan through the resistor prongs I accidentally let the pos and neg cross ... when it rains it pours not going well today
Edited: I took my fresh air box fan out of the car and tested with a 12 V battery and it spins and works. But the resistor does not seem to work: I put 12V positive lead on the upper right pole where power comes in ( I get 11.84 volts on this terminal when the ignition was on) . ... as I understand it the other three poles are ground for the three fan speeds? So I connect each one to ground and the fan does not work assuming I am testing correctly>>>> can you rebuild a resistor or perhaps clean it with contact cleaner and make it work again https://forums.pelicanparts.com/porsche-911...ower-motor.html https://forums.pelicanparts.com/porsche-914...roster-fan.html |
