When I took delivery of my 08 Expy, there was a small ding in the driver door which the dealer took care of via the services of a PDR guy. Anyway, I've just noticed that whenever I roll my window down now, there is a soft intermittent grinding or rubbing noise. This only happens when I roll the window down; going up is fine. Apart from that, the window operates normally. I was wondering how to take the door panel off to see what could be causing the problem? I'm assuming that in the process of removing the dent, the PDR guy may have bent something in the power window roller mechanism. I'm hoping that it may be something I can remedy myself without having to go to the dealership. Any advice or instruction on how to proceed?
