rear power window rattle

The driver's side rear power window on my 2001 Grand Caravan EX has a bad rattle. When I open the window there is some up and down play which the other side does not have. Is there some adjustment or do I need to purchase new parts. Thanks in advance!

Welcome to the forum. No adjustment I know of. You'll have to remove the inner trim panel and inspect the two forward attach bolts and the motor arm attachment at the rear for anything loose or worn.
