Vehicle Application and Function

The window motor used in the ML W164 model is responsible for driving the window lifting mechanism on the right front side of the vehicle. It is a component installed in the door, working in conjunction with the factory electrical controls, door panel buttons, and the comfort system. Thanks to its precise operation, it ensures predictable window movement without jerks or uncontrolled stops.

The vehicle placement specified as front – right side allows for unambiguous part matching to the specific installation position, reducing the risk of errors in component selection and speeding up service work.

Benefits of Using an Original Window Motor

Choosing a dedicated window motor for the ML W164 translates into a number of practical advantages in daily vehicle operation:

• maintaining the factory operating characteristics of the window mechanism,
• correct integration with the electrical system and comfort control system,
• proper fit for mounting points in the front right door,
• reducing the risk of improper window closing and associated leaks.

As a result, a functional window motor not only enhances user comfort but also protects the interior from moisture and external noise.

Technical Characteristics and Installation

The motor belongs to the group of components referred to as Window Regulators and Motors, meaning it is designed to work in conjunction with the window lifting mechanism and the control system. Its construction is intended for installation in factory mounting points within the door, which simplifies servicing and reduces replacement time.

When selecting a part, it is worth paying attention to:

• compatibility with the vehicle model and body generation,
• correct vehicle placement (front, right side),
• being a Mercedes part, which facilitates matching with other system components.

This set of parameters allows this motor to be considered a suitable replacement for the factory-installed component, without the need for modifications to the electrical system or mounting points.

Product Condition and Service Application

The offered window motor is a used part, making it an attractive option for operational repairs where cost reduction while maintaining adequate functionality is a priority. This type of part is suitable for both typical replacement of a worn-out window drive and for comprehensive door work, e.g., after a collision or intervention in the electrical system.

Due to its intended use, the motor is particularly useful in situations where symptoms such as slow window operation, stopping mid-travel, no response to control buttons, or improper window closing on the front right side occur.
