Driver door controls
Could be a wiring problem to the door or to the switch. Might be a burned out switch. If the driver's door uses a separate fuse from the other doors, it could be just a blown fuse.
Call dealer first, there is a recall for this, as water can get into the master switch. It affects ALL years, however, recall doesn't include all years. Tid bit for ya.....brand new ones, need to programmed by dealer. Used ones are plug and play.
