On very hot days (+85 degrees), if I roll the driver's window all the way down when I go to roll it back up it will only go up about 2 inches before stopping. That is unless I push up against the glass to get it past the point where it incorrectly stops. I was wondering if this may be from part of the window frame expanding from the heat, reducing the gap for the glass to travel through and causing the window sensor to think there's an obstruction so halting it.

Also on a less important note, today while out driving I did a pretty fast u-turn, and all the windows went down by themselves. It wasn't until I restarted the car that I could raise them again. Weird right?

 

That sounds like somehow global open was triggered.

Loose/chafed wire somewhere? Button on your fob worn or got pressed?
