Reference OE numbers: 063700-7440 0637007440 87106-12140 Function: This damper actuator effectively resolves common problems caused by actuator malfunctions, such as inability to adjust ventilation temperature (continuously blowing hot or cold air) and uncontrolled airflow. Material: The hybrid damper actuator features a robust housing and reduction gears, making it resistant to deformation. It can withstand extreme temperature fluctuations inside the vehicle, ensuring stable air conditioning . 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
