Thank you very much Mpolli. Gilly, I don't think its my regulator because it just suddenly stopped working, no noises, sluggishness or other irratic operation...it just stopped working. I guess I will know once I pull the door panel off. Like I said before, I have replaced power window motors and regulators before, just not on the MB. None of the ones that I have done before required rivets. One more quick question. Does the door panel have special clips or snaps that need to be replaced?
