Vehicle Application and Placement

The presented window regulator motor is designed for installation in the front right part of the body, in the passenger-side door. This placement is crucial for correct component selection – the part works in conjunction with the window guide, lifting mechanism, and the electrical system dedicated to this specific position.

Thanks to its proper fit with the door construction in Mercedes W177 models, the motor ensures smooth window raising and lowering, without excessive strain on the mechanism and electrical system.

Technical and Functional Characteristics

The window regulator motor is responsible for generating torque transmitted to the window guiding mechanism. In practice, this means:

• stable operation throughout the entire window travel range,
• proper cooperation with factory door control units,
• maintaining the correct raising and lowering speed,
• reducing the risk of jams and mechanism overloads.

The original manufacturing for the Mercedes brand promotes the preservation of the system's factory operating parameters, which translates into user comfort and predictable window behavior in daily use.

Condition, Origin, and Benefits of Use

This part comes from the original Mercedes components line and is offered as a used part. This choice allows for a reasonable repair cost while maintaining proper compatibility with the electrical system and door construction. Compared to low-quality aftermarket alternatives, the original window regulator motor offers better compliance with the vehicle's factory parameters.

For users planning conscious vehicle operation, choosing a used, original part can be a favorable compromise between durability and budget, especially when repairing comfort systems such as window control.

Selection by OEM Number and Practical Tips

When selecting a window regulator motor for a specific car, it is advisable to use the OEM number and vehicle data to avoid compatibility issues. If in doubt, it is helpful to compare the markings on the removed part or verify using the VIN in the manufacturer's catalogs.
