Good To Know

Q: Is the motor pre-installed, or do I need to swap it from the old unit?

A: The motor comes pre-installed on the regulator frame, so you can replace the entire assembly without transferring the motor. Simply plug in the electrical connector and bolt it into place.

Q: Will this fit if my BMW has rear window sunshades?

A: This regulator is designed for standard rear door windows; if your vehicle has an integrated sunshade, verify that the mounting points align, as sunshade-equipped doors may require a different part.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
