My driver-side window got stuck tonight, and will roll down (while hearing a slight grinding sound) and won't roll all the way up. It slows as if it's losing power, but the other windows work fine. Recently I did hear a subtle 'thump' coming from my side of the car while driving..

I'm trying to take the panel off..all I found were two screws under the arm-rest and one screw at the bottom of the panel, near one of the cabin lights. What else do I need to disconnect? Any ideas on what's going on? Thanks for any help..
