Vehicle Application and Function

The presented window regulator is dedicated to the rear left side of the Passat CC body and works with the factory window control system. It is responsible for smooth window movement within the guides and for transferring power from the motor to the lifting mechanism, which translates to comfortable window operation from the door panel or the driver's console.

Thanks to its design, which is consistent with solutions used by Volkswagen, the part maintains the correct mounting geometry and window travel path, reducing the risk of jamming, excessive play, or leaks around the door.

Construction and Mounting Fitment

The left rear window regulator for the Passat CC is designed as an OEM part, meaning it fits factory mounting points in the door and is compatible with the original control motor. The mechanism's construction allows for:

• stable vertical window guidance,
• cooperation with factory seals and guides,
• maintaining the correct range of window movement in the upper and lower positions.

Its placement on the rear left side of the vehicle allows for unambiguous identification of the mounting position and reduces the risk of errors when selecting a part for a specific side of the body.

Benefits of Using an Original Regulator

Using an original window regulator in the Passat CC helps maintain consistency with the factory door design. Key benefits include:

• precise fit to the door structure without the need for modifications,
• maintaining proper cooperation with the electrical system and window controls,
• reducing mechanism operating noise due to correct geometry and cable routing,
• preserving the comfort of using the rear passenger-side window.

Parts from this group are particularly important in cases of symptoms such as uneven window lifting, window dropping, jamming, or no response to commands from the control button.

Condition and Service Application

The offered window regulator is a used part from a dismantled vehicle, making it a sensible choice for maintenance repairs where the priority is to combine original construction with a favorable service cost. This type of part is suitable for both replacing a damaged mechanism and restoring full door functionality after bodywork and paint repairs.

If you are planning a comprehensive repair or upgrade of the door and side window area in your Volkswagen and need other parts from the same group, such as lifting mechanisms, electric drives, or window guides, check the available parts in the Volkswagen Window Regulators and Motors category.

Practical Tips and Additional Information

When selecting a window regulator for the Passat CC, it is worth paying attention to compatibility with the body version and the mounting side to avoid installation problems. It is also helpful to compare the mounting structure and cable routing with the part removed from the vehicle.
