Vehicle Application and Function

The presented window regulator motor is dedicated for installation in the front right door of BMW F40 series vehicles. It is responsible for the electric drive of the window mechanism, working in conjunction with the factory control module and door panel buttons. Thanks to precise fitting to the door structure, this component allows for maintaining the correct window guide geometry and reduces the risk of jamming or uneven movement.

Construction and Mounting Fitment

The motor is designed as a part installed directly within the door structure, in the area of the window guides. The construction includes factory mounting points and an electrical connector compatible with the BMW wiring harness, which facilitates installation and removal in service conditions. The placement on the vehicle, specified as front – right side, allows for unambiguous identification of its correct application in the bodywork.

As a part from the Doors and Door Panels group, the regulator cooperates with the door frame, window, seals, and other components responsible for interior sealing and acoustics. A correctly selected and installed window drive reduces mechanical load on the guides, contributing to a longer lifespan of the entire door assembly.

Identification Parameters and Compatibility

The product has a factory OEM part number and assigned replacement numbers, which facilitates verification of compatibility with a specific vehicle configuration. Combined with the BMW manufacturer's designation and the stock identifier, it is possible to precisely match the regulator to a given car instance, without the risk of installing an incorrect variant.

For users who wish to further confirm compatibility by chassis number or manufacturer's markings, a practical guide may be helpful – detailed instructions can be found in the article Guide: How to Select the Right Car Part by VIN and OEM Number.

Condition, Service Application, and Benefits of Installation

The regulator is offered as a used part, allowing for economical repair of the window lifting system while maintaining original BMW specifications. This type of component is particularly useful in situations where symptoms such as the window stopping halfway, no response to the control button, or uneven window movement in the guides occur.

Replacing a damaged drive with a functional part from the same construction group allows for:

• restoring full functionality of the electric window control in the front right door,
• maintaining compatibility with the factory electrical system and BMW control logic,
• reducing the risk of additional damage to the window lifting mechanism.
