Malfunctioning and failed power window regulators (mechanisms) are so common on older Mercedes that Kent can almost guarantee if you own one and drive it regularly you will have to fix one at some point. Some types like the 201 and 210 chassis rear doors with the wire cables are more prone to fail than others. Age, lack of lubrication and abuse are the key factors for premature failure.
The short above video will give you an overview of power window regulators. PLEASE NOTE: This is a general information video and does not cover every detail for every model. If you own a W116 sedan from 1973 to 1980 and are dealing with removing a front window regulator then we recommend a different video listed in the related products below:

Related Repair Details NOT included: Door panel removal is not covered in this video. Of course, the panel will have to come off to access the window mechanism but each door panel is a little different. We carry manuals and other videos that can teach you how to remove your specific panel if you are not familiar with the procedure. Please use our solutions finder to locate those resources. IMPORTANT: In order to remove most regulators from the door you will need to move the window up and down. IF YOUR POWER WINDOW IS STUCK CLOSED please see the video below that will help you remove MOST stuck window mechanisms.
