I have had three window motors replaced in 1 year ,all under warranty.Has anyone any similar problems and is there any way to avoid replacing motor and regulator.Is this acommon problem--C200 sport1995.

"C"-class windows have not been that much of a problem. Which ever window has been a problem I would made sure that that switch(s)
were checked for sticking. There is a computer that controls the windows & it could also cause a problem keeping power going to a motor. Any childern ??

Thankyou for replying so soon.No kids rear seats are rarely occupied.Only factor I have considered is the full closure safety facility on the alarm system, which lowers the windows if the alarm button is pressed inclose succession. The warranty has just expired I wonder has quality deteriorated a little?
Some think that the190 was better, that may open a debate. I would appreciate any further thoughts.
