Purpose and function in the vehicle

The window regulator mechanism is responsible for the smooth, controlled movement of the window in the rear right door, working in conjunction with the electric control system. A properly selected component guarantees:

• stable window guidance in the tracks,
• repeatable operation throughout the full range of motion,
• maintenance of door sealing due to correct window closure,
• consistency with the factory comfort window control system.

Thanks to its dedicated placement on the vehicle (rear, right side), the mechanism is structurally matched to the geometry of the BMW F25 door, which reduces the risk of stress and premature wear.

Compatibility and technical markings

The offered subassembly comes from the BMW line and complies with the manufacturer's factory standards. It has an assigned OEM part number and a set of interchangeable numbers, which facilitates precise identification and selection for a specific vehicle configuration. In practice, this means the possibility of direct installation in place of a worn or damaged mechanism without the need for system modifications.

Technical information regarding reference numbers and replacement markings is also available in the product description, allowing for verification against service catalogs and workshop documentation.

Condition, origin, and benefits of use

The item is offered as a used original component, sourced from dismantling, which allows for combining reasonable repair costs with the preservation of factory specifications. Compared to generic replacements, using the original window regulator mechanism ensures:

• preservation of the correct operating geometry of cables and guides,
• compatibility with factory door mounts,
• consistency with the vehicle's window control system,
• reduction of the risk of improper closing or window jamming.

For workshops and individual users, this means predictable installation and a lower risk of complaints related to the improper operation of the window lifting system.

Installation area and service aspects

The mechanism is intended for installation in the rear, right part of the body, within the passenger door. When replacing, it is recommended to:

• check the condition of the window guides and door seals,
• verify the correct operation of the control motor, if integrated with the mechanism,
• check the limit settings in the window control system after installation.

Such a service approach allows for restoring full functionality to the rear right window in a single operation and limits the need for repeated interventions in this area of the body.
