Vehicle Purpose and Function

The window regulator motor is responsible for driving the mechanism that moves the window in the rear right part of the body. It is a key element for driving comfort – its proper operation ensures smooth opening and closing of the window, as well as proper sealing of the vehicle interior.

Its placement in the rear right window area allows for precise integration with the factory installation, without the need for modifications to wiring harnesses or mounting points. This ensures a structured and predictable installation process for mechanics or experienced users.

Construction and Technical Characteristics

The motor belongs to the Window Regulators and Motors group, meaning it is designed to work with the factory window control system in Volkswagen vehicles. The drive's construction is optimized for the torque required to operate the rear door window, while maintaining appropriate operating speed.

The component works in conjunction with the regulator mechanism and the vehicle's electrical system, ensuring:

• stable window movement throughout its operating range,
• repeatable positioning when closing,
• compatibility with the factory window control system.

Additionally, the construction is designed for operation in conditions typical for door interiors – taking into account variable temperatures and humidity.

Component Condition and Practical Application

The offered motor is a used part, which in practice means a favorable compromise between repair cost and maintaining the original manufacturer's specifications. For many users and workshops, this is a solution that allows for restoring full window functionality while maintaining compliance with the factory manufacturing standard.

It is particularly useful in situations where:

• the original window drive has stopped responding to button commands,
• there are problems with the window stopping at random positions,
• the drive needs replacement after mechanical or electrical damage.

Benefits of Using an Original Motor

Using an original solution from the Window Regulators and Motors group in a Volkswagen vehicle ensures consistency with the factory window system design. This:

• maintains compatibility with the electrical system and controls,
• reduces the risk of mechanism fitting problems,
• preserves predictable window operating parameters in daily use.

This solution is particularly valued by workshops specializing in the Volkswagen brand, where assembly repeatability and the ability for quick diagnosis and replacement of components are important.
