So I am still on a quest to get my passenger side mirror to work - this is a motorized mirror for my 1981 300sd (w126). I found a replacement on eBay - guys said it worked and I went ahead and bought it.

In the mean time my passenger side window switch stopped working as well. The backseat right side and all the rest of the windows work no problem. However since I do tend to use the Europarts switches to save on cost I figured that it was just the switch that went out - so I ordered a replacement for that as well.

This past weekend I finally got around to swapping the mirror and the switch. I was super excited to finally have this checked off my box of w126 To-Dos! Swapped the mirror out no problem (I had mad sure I had the right version with the correct plug). I turned on the juice... UGH - Nothing! Not even an attempt to move the mirror. I was really irritated as I thought I had been duped...

So while I was working on that side of the car I went ahead and pulled out the switch for the window and replaced it with the new one. I turned the key again and guess what? The Window STILL would not work either!

So now I am stumped - could this be an electrical issue within that door? I swapped the fuse that controls that window unit as well - and still nothing?

Any thoughts? Vacuum issue? Electrical issue? The window did work for the last year and just stopped working one day (hence the reason I thought the switch went bad).

Thanks in advance!
