Application and function in the Mercedes-Benz W176

The presented component is intended for installation in the rear right door of Mercedes W176 class vehicles, where it is responsible for smooth, electric window control and audio output in this part of the cabin. Its placement in the rear right zone of the vehicle body ensures a proper fit to factory mounting points and the electrical installation.

Combining the window lifting mechanism with the speaker in a single module reduces the number of service operations, simplifies installation, and helps maintain acoustic and functional consistency with other comfort system elements in the car.

Module construction: window regulator and speaker

The item belongs to the Window Regulators and Motors category, meaning it contains an electric mechanism responsible for the movement of the window within the guides. The construction is designed to work with the factory window control system in the Mercedes-Benz W176, ensuring correct operating speed, direction of movement, and response to door panel buttons.

The integrated speaker is part of the sound system, responsible for audio playback in the rear right part of the cabin. This solution allows for consistent sound quality and a correct soundstage, while simplifying service – replacement is carried out as a single, complete module.

Benefits of using an original Mercedes component

The original module from the Mercedes brand ensures a proper fit to the door structure, factory mounting holes, and electrical harnesses. As a result, installation is predictable, and the risk of improper window operation or audio system interference is minimized.

Using this component allows for an economical restoration of the rear right window and speaker functionality while maintaining the vehicle's factory specifications. It is a practical solution in the event of mechanical door damage, window drive failure, or sound issues in this part of the interior.

Selection by part numbers and vehicle placement

To ensure full compatibility, it is worth verifying the module's compliance with the specific body version and equipment level, using the manufacturer's markings and information regarding vehicle placement: rear – right side. This approach reduces the risk of ordering errors and speeds up the installation process in the workshop.

In case of doubt during part selection, comparing the mechanism's construction and electrical connectors with the component removed from the vehicle can help confirm compatibility before installation.
