Purpose and function in the vehicle

The window motor in the rear right part of the body is responsible for controlling the movement of the window in the rear passenger door. The component works with the factory control system, responding to signals from the door buttons and the driver's panel. A correctly selected and functional motor guarantees:

• stable raising and lowering of the window without jerking,
• proper cooperation with the guides and the lifter mechanism,
• maintaining door tightness through proper window closure.

Construction and fit for the Passat CC

The motor in question has been designed with the architecture of the rear right door in the Volkswagen Passat CC in mind, which translates into appropriate mounting points and a compatible electrical connector. Thanks to this, the installation proceeds in an orderly manner, without the need for modifications to the wiring or interference with the door structure. Original origin from the Volkswagen group helps maintain factory operating parameters and correct communication with the vehicle's electronics.

Condition, verification and application

The component comes from disassembly and is offered as a used window motor, which allows for an economical repair of the window system while maintaining the original specification. This type of part is particularly useful in situations where the vehicle exhibits symptoms such as the window stopping halfway, no reaction to buttons, or uneven mechanism operation. Replacing the motor itself is often sufficient to restore full functionality to the rear right window.

Benefits of using an original motor

Using an original solution from the Window regulators and motors group in the Passat CC allows for maintaining consistency with the factory comfort system. Key advantages include:

• secure fit to the rear right door without additional adaptations,
• compatibility with factory window and comfort controller settings,
• the ability to restore full window functionality at limited repair costs.

Such a solution is particularly beneficial for users who want to keep the vehicle in a configuration close to the factory one, avoiding compatibility problems with low-quality replacements.
