[83-911SC cab]

If you have a Bentley manual it shows the fuse locations and Amps for each..but since you are asking I will assume you do not have one..If that is the case get one quick best book I bought for chasing out stuff..

That being said the fuse for the Power windows is the one closest to the firewall/dash in your fuse block and should be a 25 amp version according to my Bentley manual. You probably know the location as it should have been the one blowing and you have been replacing.

I am at Fire Station tonight but should be able to put send you a pic of window wiring tomorrow when I get home. Let me know if you need it.

But in the mean time the pass window switch has 5 connections according to wiring diagram.

1 Black wire - goes to window motor
2 Green wire - goes to window motor
3 Red/ White wire - comes from drivers side window switch for pass side
4 Brown wire -ground point
5 Red/ Black wire - comes from drivers side window switch for pass side

Hope this helps
