I had both of my windows down on my '03 325ci today. I close the passenger side door in a normal fashion (not excessively) and I hear the rattle of the window down in the door frame. I do the same thing to my driver side and dont hear the rattle.
loose window on the passenger side? how does one remedy this? Window, when rolled up, shuts fine when closing the door, just that it rattles down in the door frame whenever the door is shut.
