Vehicle Application and Function

The window motor is installed on the rear right side of the vehicle and is responsible for driving the window lifting and lowering mechanism.

This component is particularly important for:

• proper operation of the electric windows in the rear doors,
• maintaining vehicle comfort in daily use,
• ensuring proper sealing and closing of the window when the vehicle is locked.

The motor has been specifically designed for the ML W164 platform, meaning correct mounting points and a compatible electrical connector. This ensures a straightforward installation without the need for electrical system modifications or alterations to the door structure.

Key design advantages include:

• factory fit with the window guide and lifting mechanism,
• maintaining the original window operation geometry,
• designed to operate in conditions of varying temperature and humidity inside the door.

Benefits of Using an Original Window Motor

Using an original motor in the Mercedes ML W164 allows you to maintain the window system's performance parameters as intended by the manufacturer. In practice, this means:

• stable window lifting and lowering speed, without jerking or stopping,
• proper integration with factory comfort systems (e.g., window closing),
• reduced risk of overloading the electrical system due to appropriate current characteristics.

A used OEM part is also a cost-effective solution, allowing you to restore full functionality to the rear right window without the need to invest in more expensive aftermarket replacements with uncertain performance.

Condition, Verification, and Part Number Selection

The motor is a used original part obtained from disassembly. Such parts are often chosen by users who expect a factory fit and predictable component performance while keeping repair costs reasonable.

When selecting a motor for a specific ML W164 model, it is advisable to pay attention to the manufacturer's markings and reference numbers. This allows for precise matching to the equipment version and year of manufacture, minimizing the risk of incompatibility with the electrical system or window lifting mechanism.
