Designed to raise and lower the rear right door glass on command, the TrakMotive Power Window Motor and Regulator Assembly 21-0056 pairs the drive motor and the regulator mechanism in one replacement unit. It fits many vehicles, among them the 2001-2003 BMW 525i, 2001-2003 BMW 530i and 1999-2003 BMW 540i, as a direct-fit replacement for the listed applications; see the Buyer's Guide tab for the full list.
Supplied as a window regulator and motor assembly, it replaces both the motor and the regulator in one job.
- Premium cable sheathing: the regulator cable runs in premium sheathing.
- Self-lubricating technology: built into the assembly by TrakMotive.
- Upgraded plastic compounds: used in the assembly's plastic components.
- OE plug-and-play harness: designed to plug into the vehicle's factory window wiring connector.
Signs the rear right window regulator or motor may need replacing include glass that moves slowly, stops partway or drops into the door, grinding or clicking from inside the door, or a motor you can hear running while the glass stays still. Diagnose the cause first, because a switch, fuse or wiring fault can produce similar symptoms.
The listed applications use one assembly at the rear right position. Backed by a limited lifetime warranty. Country of origin: China.
