As a result, installation is straightforward, without the need for modifications or adjustments to the mounting elements.

The original Mercedes origin ensures that factory dimensional tolerances are maintained, which is crucial for door sealing, proper window closing, and compatibility with seals and trim strips.

Technical characteristics and installation

The mechanism belongs to the Window regulators and motors group, meaning it is a component of the system responsible for controlling the position of the window in the door. The design provides for installation in the factory mounting points in the front right door, while maintaining the correct alignment relative to the door frame and the glass.

When replacing, it is recommended to:

• check the condition of the guides and mounting points in the door,
• verify the correct operation of the window after installation (full range of motion, no skipping),
• check the compatibility with window control switches and the central comfort module.
