Purpose and function in the vehicle

The presented window regulator motor operates in the rear left door area, responsible for the electric raising and lowering of the window. The component works with the factory comfort control system, enabling smooth window movement via the buttons on the door and the driver's panel.

The vehicle placement is clearly defined as rear – left side, which facilitates part selection and minimizes the risk of ordering errors. The product belongs to the Window Regulators and Motors group, which are components responsible for the mechanical and electrical control of side windows.

Benefits of using an original Mercedes component

Using an original solution from the Mercedes brand allows you to maintain the factory performance parameters of the window system, including:

• correct window raising and lowering speed,
• stable cooperation with comfort modules and anti-pinch safety features (if present in the car's specific configuration),
• proper mechanical fit to the guides and mounts in the door.

For workshops, this means reduced installation time, and for the user – a lower risk of noise, jamming, or uneven window operation after replacing the part.

Installation and operational characteristics

The window regulator motor is structurally prepared for installation in the factory mounting points in the rear left door. As a result, it can be used as a direct replacement for a damaged component without the need for installation modifications or interference with the door sheet metal.

The product is in used condition, which is important for optimizing repair costs – especially in the case of older S-Class W220 models, where economical part selection is significant. At the same time, the functionality required for the proper operation of the window system in daily use is maintained.

Selection by numbers and vehicle fitment

For precise part selection, you can use technical markings such as the OEM part number or available interchangeable numbers. This allows you to verify compatibility with a specific equipment version and vehicle year, as well as compare the element with the one currently installed in the car.

In case of doubt, it is also useful to refer to the SKU identifier, which in our system clearly defines this specific window regulator motor. This allows a workshop or individual customer to easily refer to the correct product during consultation or reordering.
