This past weekend someone attempted to break into my 300E, and screwed up the alingment of the passenger front window. It will go down fine, but when I try to roll the window up, the end towards the rear of the door, gets caught up or off of the track. I have not owned a MB before and have never removed any of the door panels. When I go to remove the passenger door panel, is there anything that I should be extremely cautious with?
