Purpose and vehicle placement

The presented motor is designed for installation in the rear left part of the body, in the passenger door area or the driver's side rear door (depending on the body configuration). It is responsible for driving the window regulator mechanism, working in conjunction with guides and cables, which allows for precise positioning of the window within the guides. The placement on the vehicle is factory-defined as rear – left side, which minimizes the risk of error when selecting parts and facilitates identification when planning repairs or replacing a damaged drive.

Technical and functional characteristics

The window lifter motor operates within the vehicle's electrical system, controlling window movement in response to signals from the door control buttons or the driver's panel. As an item from the Window regulators and motors category, it is adapted to work with the factory wiring and control modules used in the Volkswagen Golf Plus. Key functional features include:

• stable operation within typical load ranges of the lifter mechanism,
• capability for multiple window lifting and lowering cycles under daily operating conditions,
• factory-designed mounting points, facilitating installation in the original door structural holes. Thanks to the use of an original solution, compatibility with the factory window control system is maintained, which limits the risk of communication errors in the vehicle's electrical installation.

Benefits of using an original motor

Using an original window lifter motor in a Volkswagen Golf Plus allows for maintaining the structural consistency of the entire door system. Proper fitment to the guides, mounts, and wiring harness translates into:

• reliable window mechanism operation without jamming or unwanted play,
• preservation of the factory window movement speed,
• reduction of drive noise during lifting and lowering. Choosing an original component from this group is particularly important for vehicles used daily, where operational repeatability and predictable window system behavior are essential.

Condition and use in repairs

The offered motor comes from dismantling and is a used component, which allows for economical repair of the window system while maintaining the manufacturer's original specifications. This type of solution is often chosen for post-accident repairs, replacement after wear and tear, or when experiencing issues with the rear left window operation. Before installation, a standard service procedure is recommended, including checking the condition of the lifter mechanism, guides, and window seals to ensure proper cooperation of all components and avoid overloading the drive.

Selection by numbers and technical aspects

The motor is associated with a specific OEM part number and additional interchangeable numbers, which facilitates precise identification in catalogs and selection systems. When planning a purchase, it is worth using the part number or reference numbers to confirm compatibility with the specific equipment version and model year of the Volkswagen Golf Plus.
