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 |

Found the thread Drphil914 started.
Might have some info that will help you. Also has info on my motor (couldn't be fixed) and the URO replacment. Also don't forget while you're in there, 914Rubber sells new gaskets and seals, and hardware to completely rebuild the fresh air box if you're in need. http://www.914world.com/bbs2/index.php?sho...=351152&st= |
