Mercedes: Window Repair, mercedes benz 420sel, mercedesshop

Question
My window on my 1990 420sel does not go up all the way any more. What is the secret with getting the drivers side inside panel off without breaking any support clips. There is only three inside handle screws that can be seen to remove.Any help to get to the inside of that door would be appreciated. Thanks.

Answer
You need the graphics on http://alldatadiy.com/ to remove the panel without damage.

Best guess:
Window Regulator and/or motor is bad.
