Purpose and Fitment

This ensures the part works well with the factory electrical system and window controls, simplifying installation and reducing the risk of compatibility issues.

The precise placement on the vehicle avoids selection errors and ensures proper mechanism operation at the specific body point.

Technical and Functional Characteristics

The window regulator is part of the components responsible for smooth, controlled raising and lowering of the window in the door. Its construction is adapted to the window's weight and the operational loads typical for a large SUV like the Discovery 4. The mechanism works with the factory control motor, ensuring stable window movement within the guides.

Original sourcing from the Land Rover brand helps maintain the appropriate rigidity of the entire system, leading to less wear on cooperating parts and reduced noise during operation.

Practical Application in Service

The rear right window regulator is particularly useful in situations exhibiting symptoms such as:

• window jamming in the upper or lower position,
• uneven window raising or lowering,
• no response to controls despite a functional electrical system.

Replacing with an original part from the same category restores correct system operation without the need for modifications to wiring harnesses, mounts, or guides. This solution is highly valued in professional workshops where assembly repeatability and predictable repair outcomes are crucial.

Condition and Benefits of Choosing a Used Part

The offered regulator comes from the secondary market, representing a sensible compromise between repair cost and maintaining the vehicle's original specifications. Choosing a used OEM part allows for cost savings while maintaining factory-standard manufacturing and fitment to the body and electrical system.

For workshops and individual users, this means the possibility of a quick, technically correct repair without resorting to aftermarket replacements with uncertain fitment.
