Window problems in 190E
 

The driver's window went down but won't go back up. I tested the switch by replacing it with a good one, but no luck. The window will engage to go down, but not up. From what I've read, that leads me to think that there may be a broken wire.

I've taken off the inside door panel and the kick panel. The wires seem to go inside the wall on the car side. I can't reach them on the door side because the window is down and in the way. I can't even see the wires on the motor to try and jump it.

Can anyone help me? Any suggestions would be welcome.

Try searching. There should be some info on that. My car is different.

Tried using a good switch and it didn't work, so I assumed a broken wire - I was wrong! The child lock-out button HAS to be connected when you try another switch because it provides the ground. If you swap switches when looking for a window problem, make sure you plug in the lock-out switch too!

Finally, a low cost fix on a MB.
