This used OEM BMW left rear power window regulator (5A01D21) also replaces OEM numbers 51354876379 and 4876379. It controls the sliding glass movement in the door, and when the regulator fails, the window may become stuck, drop into the door, or move unevenly—often due to a broken cable or worn plastic carriers.
