It sounds to me like a loose connection to one or both window switches. Before you buy an expensive part, pull your switches, clean and check connections. If that does not fix problem, get the circuit diagrams and trace out power and connectivity. Throwing parts at a problem is good for the parts guys, but if it's not the right part, you will still have the original problem.
Good luck,
Dave

I need some help. My passenger door will not close without slamming the door an few times. However it closes perfectly the first time if the drivers door is open or the passenger window is open.

I want to install a time delay relay using the door light switch as a trigger. When the door is open the trigger will lower the window for a few seconds (x) and when closing the door the window will close the window for x seconds.

Which wire/s on the switch controls the up and down function movement ?

Hi Reuben. red/black and red/white. You'll need your mulitmeter to figure out which is the up and which is the down. The black and the green go to the winder motor and brown is ground (earth). Sounds like a good idea, Bill.

I had similar problem...fought it forever. Finally determined the wire going through the door to the switch had a kink in it and would randomly make/lose connection. Drove me nuts thinking I'd fixed it.

I have a passenger window problem that differs from the OP's. In my '87 Carrera, both driver door switches work, but the passenger door switch does not. I have tried swapping the switches, but the problem persists. Any ideas? TIA.

I'm sure that I don't have the same problem. I can lower and raise the passenger window with the switch on the driver's door, but the switch on the passenger door will not raise or lower the window. Swapping the working driver door switch to the passenger door did not fix the problem.

Fixed my pass side today. Window would not raise. Hit the door panel by the switch and it started going up and back down then quit again. Removed the door panel, window switch, checked the wiring, cleaned all contacts, sprayed contact cleaner into the window switch. Works like a charm now.

FLOJO!

How many times was that motor drove into the hard stop up or down side to create the cracks on that motor!? Wow. When I started fussing with my motors in the doors I was expecting to see such a mess, but those motors are quite over-engineered with AlCuZn (or some zinc alloy) for the gear box: you may want to send that to the PE at Porsche to see how he reacts.
