The rear passenger side window won't go up when I press up on the window switch. If I pull the window up with my hand while lifting the switch, then it goes up slowly. When the window is closed and I open the door, it does not go down to clear the trim. It's -15 C outside, and this problem started when I was cleaning the ice off the rubber window seal. I have a feeling some ice may have gotten stuck down in the door somewhere, preventing the window from going up. This video shows what happens when I press the switch up. The window tries to go up, then goes down immediately. I've tried rebooting the MCU and recalibrating the window (by holing the switch down for a few seconds when the window is all the way down). Nothing seems to work. Anyone know what the problem is or how I might be able to fix it without a service centre visit?
