Well I have problems with my driver side window too. I opened it up and the clips holding the window are fine. I sprayed it and closed it up but it's still tilting forwards. I'll have to take it apart again to find the problem(not rush as of yet but soon) . Is it possible the front rail popped loose (spot weld let loose?)
Well I just installed a rear camera an am pretty happy with that I couldn't pass it up they have the complet wireless ones at COSTCO for under $90. One funny thing I find is I can pick up other wireless cameras on the monitor as I drive around, when I leave the screen on
