window switch wiring diagram
I removed the rear passenger door panel to trace down an air leak, and in turn pulled the back of the window switch cover off. All of the wires came loose and now I cannot get the window to go back up. I matched the pinout to the rear driver side switch except for two wires that are different colors. I tried every combo and still no go. Does anyone have the wiring layout of these switches, and /or recommendation on this issue? Thanks for any assistance..

Last year when I Restored My SEC someone cut into all of the window switches and ran relays for a self closing system. I had to go through ALL of the wiring in the cabin to restore it.

A great explanation!! It first baffled me 20 years ago fixing a window switch on a old 108 car I bought for parts. I find this same circuitry with with heater controls and lots of accessories in Mercedes. Now I always also test for ground when testing a switch.

I need this same information. Can someone please post the answer here so future searches are more fruitful than mine was?

It's in the ETM. Did I not send it to you?
This is out of the 83-85 ETM manual. See if it is closer.
