Same for me, driver side. I took my car in for a state inspection sticker, and when the kid brought it back, the window wouldn't go up all the way. It was in the winter, thought something was frozen inside the door.
Took the door panel off, found the T end of the door stop had come in contact with the front window track, pulled it and bent it to hell.
I pulled the speaker out and was able to reach in to form and bend the window track back into somewhat original shape, not easy. Had to cut out one really f'd up part with a dremel. PITA!
I started with nothing......and still have most of it.
