Every once in a while when I roll up my passenger front window, the rear of the window comes up out of the track, such that the window is now at a 45deg down angle. I can fix it by rolling it down as I push down on the rear, and it usually comes up right the next time.

I do hear a bit of squeeking as it goes up, so I'm going to try to lubricate the rubber seals and hope that works.

Anyone else have this problem? How did you fix it?
