Keystone BM1551115 Rear Right Power Window Regulator Without Motor

The Keystone BM1551115 is an OEM-replacement rear right (passenger side) power window regulator designed for the BMW 5 Series E60/E61 (2004–2010). This regulator restores proper power window operation to the rear passenger door and is sold without a motor, making it ideal when the mechanical regulator assembly has failed but the existing motor is still functional.

Window regulators are the internal mechanical linkage system responsible for raising and lowering your door glass. Over time, the cables can wear or fray, the regulator can fall off its tracks, or plastic components within the assembly can crack — any of which will leave the window stuck, typically in the down position. Replacing the regulator assembly is a straightforward repair that restores full functionality.

Key Features:

• Location: Rear Right — Passenger Side
