Purpose and function in the vehicle

The presented mechanism is dedicated for installation in the front right door, where it is responsible for the precise guidance of the window and the transmission of drive from the electric motor to its movement. The design has been engineered for a specific body type, ensuring that the correct mounting points, guide geometry, and window travel range are maintained.

As a component from the Window Regulators & Motors category, the mechanism works with factory window control switches and the vehicle's electrical system, allowing for the preservation of original functionality, including smooth opening and closing of the window from inside the cabin.

Construction and performance parameters

The window lifter mechanism utilizes a system of guides and drive transmission elements matched to the weight and dimensions of the window in the front right door. A properly selected gear ratio ensures smooth movement without jerking, and the support structure is prepared for operation under typical passenger vehicle usage conditions.

This solution allows for:

• stable holding of the window in a set position,
• reduction of play and vibrations while driving,
• proper cooperation with the factory control motor,
• preservation of the factory window opening range.

Selection by numbers and compatibility

The mechanism has been developed as an OEM part, which means its geometry, mounting points, and method of cooperation with the electrical system correspond to factory solutions. In practice, this facilitates selection for a specific door configuration and equipment level, and minimizes the risk of installation problems.

To select the component consciously, it is worth using part numbers and interchangeable numbers assigned to this model – this allows for verification of compatibility with a specific equipment version and vehicle year. For more complex window system repairs, an expert guide on selecting used components by OEM numbers may be helpful, which you can find in the article Why it is worth buying used gearboxes and engines – facts instead of myths.

Condition, origin, and practical application

The offered mechanism comes from dismantling and is marked as a used original component, which in practice means maintaining the factory design and fitment to the body. This type of part is a particularly attractive solution for maintenance repairs when the goal is to maintain the original vehicle specification at reasonable service costs.

Replacing the window lifter mechanism is recommended in situations where problems arise with the smoothness of window movement, jamming, dropping, or lack of response to controls while the electrical system is functional. Using an OEM component from dismantling allows for restoring the correct operation of the system without the need for modifications to the door or electrical harness.
