Purpose and function in the vehicle

The window regulator with a built-in motor is responsible for stable, controlled raising and lowering of the window in the front right door. The component is prepared for operation within the factory control system of the Range Rover, ensuring the correct window movement speed, appropriate clamping force, and compatibility with the door control switch and the central comfort module.

Its placement in the front right door area makes the component significant for both the driver's comfort (in right-hand drive versions) and the passenger's. A properly functioning mechanism reduces the risk of jamming, uneven window guidance, or excessive electrical system loads.

Construction and design advantages

The window regulator with motor is a complete mechanical-electrical assembly in which the guides, cables, and electric drive are perfectly matched. This solution:

• ensures stable window guidance throughout the entire range of motion,
• minimizes mechanism operating noise during opening and closing,
• reduces the risk of motor overload thanks to properly selected gear ratios.

Thanks to the integrated solution, replacement is carried out in a single service process, without the need to separately match the drive and the mechanical part. This translates into shorter installation time and a lower risk of errors during door assembly.

Condition, fitment, and service application

The item comes from a Range Rover vehicle and is intended for re-installation as a used part. This type of component is particularly useful for repairs involving damage to the window lifting mechanism, seized guides, or electric drive failure. Using an original solution from the same model group allows for maintaining the factory operating parameters of the system.

During installation, it is worth paying attention to the correct positioning of the window in the guides, proper tightening of the mounting points, and correct connection of the electrical harness. Careful installation reduces subsequent play, vibrations, and improper window closing, which is important for door sealing and cabin acoustic comfort.

How to select the correct window regulator by OEM number

When selecting a window regulator with a motor for a Range Rover, it is crucial to compare the OEM number and the vehicle placement to avoid installation and electrical compatibility issues. It is also worth verifying the body version and the mounting side, as mechanisms for the left and right doors differ in construction.

If you want to check step-by-step how to safely match a used part by OEM or VIN number, a practical guide will be helpful: how to select the right car part by VIN and OEM number. It will make it easier for you to verify the compatibility of the purchased regulator with your car's specific configuration.
