Application and Function in the Vehicle

Its placement on the vehicle in the rear right section of the body allows for direct replacement of the existing motor without interfering with other areas of the vehicle. This limits the repair to the specific door area, which simplifies servicing and reduces vehicle downtime.

Compatibility, Identification, and Selection

As a Land Rover part, the window regulator motor has been designed to maintain factory operating parameters and proper fit with the door structure of the Discovery L550 model. It is always advisable to confirm the correct part fitment for a specific vehicle version based on the OEM number or catalog data to ensure compatibility with the electrical system and the guide mechanism.

The product has assigned interchangeable numbers, which facilitates the selection of a replacement based on service documentation or a parts search engine. If you have doubts about the selection, it is helpful to compare the housing shape, type of electrical connector, and mounting method to the door structure.

Performance Characteristics and Advantages

The window regulator motor in the rear right section of the body is responsible for stable, repeatable window operation, which is important for both passenger comfort and cabin sealing. An efficient drive reduces the risk of jamming, uneven window movement, or overloading of the guide mechanism.

Key benefits of using this component include:

• maintaining the factory mounting geometry in the door,
• proper cooperation with the window control system,
• the ability to restore full window functionality after the failure of the previous motor.

The product comes from the segment of used original parts, allowing for economical repair while maintaining a construction consistent with factory solutions.

Condition and Service Purpose

The offered window regulator motor is a used part intended for service applications in Land Rover Discovery L550 vehicles. It is suitable for both typical replacement of a damaged drive and for phased restoration of the complete window adjustment system in the rear part of the body.

Due to its factory origin, the part retains the correct mounting points and connector type, which simplifies installation and reduces the need for electrical system modifications. This is a practical solution for workshops and individual users who expect compatibility with the original vehicle construction.
