The window not going up straight getting cocked and jamming stems from the regulator being worn. The horizontal bar that holds the glass rides on the vertical track. There are plastic blocks that snap into the horizontal bar that keep it from rocking front to rear too much. I found that the blocks on the rear were worn because the window it is not quite balanced on the track, making it heave to the front. This causes the rear block to ware. I added a small zip tie around the block to take up the slack. That keeps the window level as it rises. I cleaned and lubed the track and cables with lithium grease and also cleaned and lubed the window rubber with silicone spray. The windows have been working grate ever since. I do expect to have to replace the regulators at some point.
