Reference OE numbers: 68164960AA Function: This actuator is specifically designed for controlling a mixed airflow damper, precisely regulating the ratio of hot to cold air. Whether you need powerful defrosting or ultimate cooling, you can enjoy a consistently precise and comfortable interior temperature. Materials: The door actuator housing features a tightly sealed design, effectively preventing dust and moisture from entering the motor, reducing short circuits, and ensuring stable in rainy or snowy weather. Precise Temperature Control: Provides precise temperature control across the entire vehicle, correcting thermal imbalances. It precisely drives the heating/cooling mixing damper, resolving cooling and heating failures, and simultaneously regulates the internal and external air circulation modes, ensuring uniform and controllable temperature across all vehicle air conditioning zones. Installation: Requires no modifications. Simply remove worn parts for direct replacement. Its compact structure fits well in confined vehicle repair spaces, making installation and removal quick and easy, significantly reducing installation difficulty and repair labor costs., Manufacturer: SZTMYVUW
