[V8] Electric window problems

[Daniel Hussey]

Hi...   I am having a problem with a 1993 V8 Quattro.

Passenger side window will go down, but not up.  Has the same symptom from both driver's side switch and switch on passenger side.  I pulled the switch on the pass side and replaced it with a known good switch.  Still wouldn't work.  So, I looked at the wiring in both the passenger side and driver's side door jams and they all appear to be fine (no visible breaks).  So, then I pulled the door panel and pulled the window regulator loose.  I was able to reverse the green and black wires to the window regulator (which switches the polarity and the direction of the motor) and was able to get the window back up, but still not sure what is causing the window to go down, but not back up.  

I'm thinking there must be a relay or something that isn't working properly.  I also heard someone say that if the driver's side window switch isn't functioning, the passenger switch won't either?  Is this correct?  If that's true, Audi must have put team door handle in charge of wiring for this car.  

Any input greatly appreciated.  I'd like to work on it this afternoon and get it fixed and pieced back together again.

Thanks,
Dan
