Danielle’s driver side window ended up coming out of the track at the front, so she wasn’t able to roll it up without holding it. By unbolting the front rail I was able to get it all aligned, but it seems her window has some wear in front of the lift mechanism. This causes the window to settle into place slightly ajar, requiring a gentle nudge to get it into place. If it was easier to get inside the door I’d look at disassembling the mechanism and fixing the bushing (or whatever), but for now I’ve left the window semi-operational.
On request the handle has been left off of the door panel (and set inside one of the map compartments) so she won’t roll the window down without remembering the slight effort required to fully re-seat it. Properly reinstalling the handle will just require clipping it back in place, but I won’t do so yet.
I suspect that this issue happened when the car was iced over and an attempt to roll down the window was made. The window was probably stuck in place and the force of pulling down on it deformed a bushing or some other part in the front of the mechanism, allowing it to wobble the current 1cm or so.
