Hello Again
I've got a 1988 190E 2.3 and none of the rear windows are operating from any switchs, the front window operate fine so based on the fuse block where the front and rears share fuses I assume the fuses are good. What am I missing, is there another fuse or breaker I'm not catching? The windows don't make a sound and they stopped working at the same time so I'm thinking it isn't the regulators
Thank if you can help
Tom

If there is a problem with the main switch the rear switches will not work. There are exceptions to this but I would look at the lock out contacts they handle the power to the rear first.

Good luck
Robert

Thanks I will check that out and let you know

Funny this happened to me recently too, except I lost one then a few days later lost the other. Let me me know what you find.

Is it possible that you may have a control unit for the windows? It's an electronic control unit for the windows. On my E320 it is PN 124-820-48-26 located under the LR passenger seat. The unit or wires may be corroded or damaged.

not in a 123 or 126 (85 and down)
