Electrical issue: passenger windows won't move

[hi its me alec]

this is on my '86 325e with power windows..

both driver windows work perfectly, but the passenger windows won't move and are stuck in the up position (thank god.) i already tried swapping switches and fuses, none worked. what would be the best way of troubleshooting this problem?

Its most likely a motor or regulator thats toast. I actually have the same problem with mine right now (thats why in my auto-x sig, the window is up)

Really? I'd hate having to deal with that, lol.

I figured it was electrical since the driver's side works flawlessly every single time.. it would be weird if that side is perfect and the other side is completely fooked. I guess it's very possible though.

"driver windows work perfectly" makes me think this is a four door car. While it is possible that both passenger window motors failed at the same time, a more likely scenario is a electrical fault at the switches on in the harness that isn't supplying power to the doors.

did they both stop at the same time?

It could be the electrical connectors/pins in the door jams, or you have 2 dead window motors. Pull the rubber boots in the doors back, pull the connector back, spray electrical contact cleaner, re-attach and try them. if that does'nt work, you will need to pull the door trims and check the motors.
