Purpose and vehicle placement

The presented window regulator with motor is designed for installation in the rear left part of the body. It is responsible for precise control of the window movement in the door, working in conjunction with the factory electrical installation and the window control system in the Mercedes.

The dedicated placement on the vehicle reduces the risk of fitment issues, and the design, consistent with the manufacturer's solutions, allows for maintaining the correct geometry of the guides and smooth window operation.

Technical and functional characteristics

The window regulator integrated with an electric motor belongs to the group of components responsible for stable and repeatable window mechanism operation. The applied electric drive works with factory door switches and central window controls, enabling convenient operation from the driver's and passengers' seats.

A solution based on the original Mercedes design ensures:

• correct window positioning in the guides,
• appropriate drive force when lifting and lowering,
• compatibility with factory mounting points in the door,
• consistency with the vehicle's electrical system.

Component condition and benefits of using a used part

The offered window regulator is a used part, which allows for an economical repair of the window system while maintaining the original manufacturer's specifications. Choosing such a solution is particularly beneficial when you want to preserve the factory door construction and ensure compatibility with existing electrical harnesses.

Using an original, used component from the same model line reduces the risk of compatibility issues that may occur with replacements featuring different geometry or a different type of electrical connector.

Application in service practice

The window regulator with motor is suitable both for typical replacement of a damaged mechanism and for post-collision repairs when it is necessary to restore full door functionality. This component is essential for:

• maintaining tightness and proper window closing,
• ensuring acoustic comfort inside the vehicle,
• trouble-free window operation from the driver's panel,
• proper cooperation with vehicle comfort systems.

Thanks to the original Mercedes design, the installation proceeds in an orderly manner, using factory mounting points and the harness routing paths provided by the manufacturer.
