This Dorman window motor and regulator assembly is a practical fix when a factory assembly fails from damage, fatigue, or collision impact. If a worn regulator or a failed motor is the cause of a rear left window that won't move, binds, or slips in the track, this unit is designed to help restore the door's original power-window operation. Diagnose the cause first, since switches, wiring, and fuses can produce similar symptoms.
