Purpose and function in the vehicle

The presented window regulator operates in the rear right window area, responsible for the smooth raising and lowering of the glass in the door. As a component of the system responsible for window operation comfort, it must maintain appropriate structural rigidity and correct guide geometry so that the window moves without jamming or excessive play.

The placement on the vehicle in the rear right part of the body means that the component is matched to a specific side and should not be used interchangeably with elements from other mounting positions.

Benefits of using an original regulator

Using an original solution dedicated to the Mercedes brand allows for maintaining the factory operating parameters of the window mechanism. In practice, this means:

• proper fitment with the door structure and mounting points,
• appropriate window guidance throughout the entire range of motion,
• reduced risk of overloading the control motor,
• maintaining proper cooperation with the vehicle's electrical system.

For the user, this translates into stable, predictable window operation and a lower risk of repeated service interventions in this area.

Characteristics of the used component

The window regulator comes from the secondary market, which allows for combining an attractive purchase cost with the preservation of the original design. This type of component is particularly interesting for repairs of older vehicles, where both technical compliance and a rational approach to the service budget are important.

Choosing a used window regulator is often an optimal compromise between durability and cost, especially when you want to maintain the original mounting specification without resorting to universal solutions.

Professional application and part selection

When selecting a window regulator for the rear right window in a Mercedes, it is crucial to pay attention to compatibility with the specific body model and door configuration. The product has an assigned OEM part number and interchangeable numbers, which facilitates verification of compatibility in service catalogs and part selection systems.

Thanks to this, mechanics and users servicing the vehicle themselves can precisely confirm that the selected element will work with the existing installation and door structure, without the need for modifying mounts or wiring harnesses.
