Buick Mechanic: Dan, Technician replied 11 months ago

Yes, I'm here. The common problems are broken wiring in door jamb or ground 301. While holding window switch down grab wiring harness in door and wiggle it around, if window moves you know wiring is problem. If not, clean ground 301 which is under the door sill. Here is a picture of ground, let me know if you have questions. Thanks
