Reference OE numbers: 063800-7960 87106-47120 0638007960 Function: This hybrid damper actuator's control mode moves the damper to the desired position, determining the airflow direction and the temperature of the recirculated/outdoor air entering the vehicle, thus keeping the cabin cool and providing a comfortable temperature. Installation: Designed for compatible vehicle models, this actuator is completely identical in size and function to OE parts, simplifying cabin temperature and airflow control. Installation is very simple—simply recalibrate your HVAC system after installation for optimal results. 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
