Hi,
Passenger side crapped out in 2001
Rear passenger side clunked out in 2004
Rear driver side gave in few days ago.
I guess driver side doesn't have too much life left in it.
All MB owner/dealer knows about this problem.
Isn't MB supposed to be making high end vehicles?

 

sadly, this issue with window regulators isn't so much "if" .....but "when?" the probability is so high that one is almost compelled to purchase one just to have, so that the inconvenience suffered is moderated. unfortunately, you're not sure which one will go out next.
