Hello,
I've got this problem that drove me crazy and then all the mechanics I've been to...
It goes like this: first one of the front power windows and side mirrors stops working, then the issue spreads to the other front window and mirror, then the central locking system, the trunk and the windshield wiper and sometimes even the signaling system stop working. Then all starts working again like nothing ever happened.

It happens particularly in damp weather and not when is hot and dry or very cold.

I have changed the module to one of the front windows, the motor and module of one of the rear windows...
Somebody said that it could be a relay, but the mechanic said that the window circuit has no relay...

Does anybody have a clue what may be wrong?

Thanks,

Dragos

Try the relay. 002-542-22-19. list price is $33.50 MSRP, but yeah that should solve you problem.

I have a 98 c230 with the same problem with one exception mine never starts working again. Please let me know if that works for you. I am going to order the relay today.

I unplugged my rear right window motor, and everything has been working perfectly. I just can no longer roll that window up or down.. Not sure why it solved my similar problems, but is worth a shot and is something anyone can do.. not time consuming and I’d even try the other rear motor unplugging if one side doesn’t solve it. It’s worth a shot. And I hope this helps and wish you the best of luck. These cars deactivate circuits and will cause unnecessary anxiety due to poor electrical engineering.
