The regulator belongs to the group of components referred to as Window Regulators and Motors, meaning it is responsible for transferring the drive from the window control system to the actual movement of the window in its guides. The construction is designed to work with the factory electrical system and comfort controllers used in the Mercedes S-Class W220.

Key functional features of this component include:

• factory fit for the rear right side of the vehicle,
• maintaining the correct vertical window travel range,
• compatibility with original window control switches,
• possibility of installation in place of a worn or damaged mechanism without structural modifications.

This allows the regulator to be used in both routine repairs and comprehensive window system overhauls of the vehicle.

The component is offered as a used part, which significantly reduces repair costs compared to new components, while maintaining the original manufacturer's specifications.
