Drivers Side Door Windows (both of them) Problem

2768 Views 8 Replies 5 Participants Last post by  keyhole
Just noticed last night, that both windows on the driver's side lower themselves slightly when I open the driver's door, which I believe is intentional and designed to reduce wear on the seals when opening and closing the doors. However, now neither window is going back up when the door is closed, not even when I lock the car.

Is this a common problem?

Is it an easy fix I can take care of on the driveway, or is MB Sugar Land going to get another handful of my Ben Franklins to put this right? Monsoon season is nearly upon us down here in Houston, and I really don't want to come back to wet seats day in day out.

We haven't had a post on this topic for quite a while.

This power window feature is called the Short-stroke in the WIS, and the details are shown below for, your interest. It can be noted that one of the pre-requisites for the operation is that the window is normalized. As with many aspects of this car, MB have 'engineered the sh1t' out of the feature, as my old boss would say. :)

The reasons for short-stroke are not too clear. I always imagined that it was to prevent a high air pressure situation when the doors are closed quickly - but that would not be a problem on the cabriolet, would it?

I do know (from experience) that if the side windows are covered in frost/ice, they can be stuck in position and this short-stroke movement will be prevented. In those situations, I always use a de-icing spray to remove all the ice on the window glass before using my remote key to open the door.
