1999 Mercedes Benz E320 Windows

The windows probably just need to be normalized. To normalize raise window using first position on window switch. By this I mean as you pull the switch you should be able to only pull halfway up and the window should raise. This is position 1 on the window switch. Position 2 (switch all the way up) is your auto up feature. So raise your windows fully, one at a time, and hold the switch in the up position for 5-10 sec. Now roll the windows down and hold for 5-10sec. Your windows should be normalized. Sometimes this will take a couple attempts to get it right.

Oh this I hope I read this before I broke my window. What I did is forcing the window up while holding the up switch.

Forcing it is not necessary and may cause damage to either the window, the window motor, or regulator. The two stage window switch is tricky on this vehicel and most clients never even realize there is a first stage, since the auto up feature is what we tend to use primarily.
