Wife's 94' GP power window on pass. side went down and won't go back up. Anybody know or have a diagram with which wire does what? I'm sure its a broken wire in the door jam area, just don't know what wire does what. Thanks!

Check the window's switch itself. There are only 2 wires going to the window motor, which operates on DC voltage. The switch reverses polarity to the motor allowing it to turn in opposite directions. One direction for up, and opposite direction for down. If the window went down, I would suspect the wires to the motor are OK.
Hope this helps you.

There may be a generic diagram in the back of the Haynes manual. Closest I have is for an 80's Olds. Not the greatest but it helped when I needed it.
Power/control to the passenger door comes from the drivers door. It may be the driver's door switch that's the problem. That's the one I normally find bad.

You might find a wiring diagram at your local library. I know the one in downtown Chandler would have the diagram. They also have copy machines.
