Hi guys, I've bought a used 2008 G35 about a year ago. I love the car, but I'm fairly confident that its been in a accident. The driver's side window motor works fine, but whenever I roll down the window it shakes violently. If I roll the window back up then bring it back down its smooth like it should be, so it makes me think that its just getting realigned on track. I was wondering if anybody else has experienced this, and if this would be an easy fix. Any help would be greatly appreciated!
