anyone else have window problems??? well basically sometimes my drivers window wont go back up symetrically, and the larger side of the window will lift right up and tip forward out of its runner, thus pulling the front egde of the window(the side of the window that runs down the windscreen pillar) out of its runner, which then causes the window to not go back to the top leaving a gap. i know on the corner of the window there is a plastic clip affixed right through the window that holds the window in its tunner, do these wear?? and has anyone else had/fixed these problems?
