My driver side window was doing the very same as described above. I had a radio/speakers installed today and i guess something finally crapped out while they were putting it all back together as they could not get the window back up. They called me back to their garage and i messed with it with them. Anyways, now it won't even budge anymore. Usually i just had to fiddle with it for a minute and let it go up in its spurts, now nothing. The guy that was installing it did like pictured above with putting the "prob" on the wires to try to bypass the switch or whatever. This did not not get the window to move either. I'm assuming this means the motor is shot? Also, the motor feels pretty hot.
