Function and Performance Parameters

The regulator motor ensures smooth window raising and lowering, providing:

• seamless integration with the Smart factory electrical system,
• adequate driving force for the front passenger-side window,
• stable operation under typical urban and non-urban driving conditions.

By utilizing an original solution integrated with the regulator, the correct window travel geometry and proper cooperation with door guides and seals are maintained.

Advantages of Using a Used Original Part
