Hey Daniel, just looking at the photos you posted... It looks like the mechanism is out of line, either bent or maybe the guides aren't in their slot ?
The glass shouldn't be that tight to one side.
Have you opened the panel ? The little grate below the window will let you see inside, but you'll have to pull the interior panel to really get at it.
I'm also wondering if the glass is correct..... Assuming that the picture show it all the way rolled up, it looks long/tall to me. Might be that someone just threw something in that worked at the time.......
There should be a part number in the bottom corner that'll tell for sure.
How this sheds some light on the problem.
Scott.
