Purpose and Function in the Mirror System

The presented actuator motor is responsible for the precise positioning of the mirror glass in the vertical and horizontal planes, on both the left and right sides of the vehicle. The component works with the factory door controls, allowing the driver to quickly adjust the field of vision to current driving conditions.

The memory function allows for saving and recalling selected mirror positions, which is particularly useful in cars used by multiple drivers. This ensures the adjustment system remains consistent with the seat and other comfort settings.

Construction and Mounting Compatibility

The motor is designed as an OEM component dedicated to Mercedes vehicles, ensuring proper fit with the exterior mirror construction. The connectors and mounting points are compatible with factory solutions, facilitating installation in place of the original component.

The placement on the vehicle includes both the right and left sides, allowing the same type of actuator to be used in both mirrors, as intended by the manufacturer. This maintains consistency in the adjustment system on both sides of the car.

Performance Parameters and Application Benefits

Using this motor in exterior mirrors ensures:

• stable operation of the adjustment mechanism within typical mirror movement ranges,
• smooth response to signals from the door control switch,
• integration with the memory system, if the vehicle is equipped with it,
• maintenance of the factory operating characteristics of the mirror system in Mercedes cars.

Thanks to its construction, which is consistent with the vehicle manufacturer's solutions, the adjustment system remains compatible with the original electrical installation, without the need for modifications to wiring harnesses or control units. This is a beneficial solution for both routine repairs and for restoring full functionality after mechanical damage to the mirror.

Component Condition and Service Application

The offered motor is a used part, making it an attractive cost-effective alternative while maintaining proper functionality. It serves as a service part in case of mirror adjustment failure, problems with the memory function, or after damage resulting from collisions or impacts to the mirror housing.

Actuator replacement is a typical workshop operation within the scope of Exterior Mirrors and can be performed either in a professional service center or by experienced users with the appropriate tools.
