Detailed Description

The Four Seasons 73799 is an HVAC blend door actuator used to move the air door inside the climate control housing so the system can direct airflow and temperature blend correctly. It is listed for 2010-2013 Subaru Forester models with dual zone climate control, making it a fitment-specific replacement for the original actuator in that configuration. The arm linkage, 6-pin terminal layout, and three-ear mounting design help match the factory-style setup. This part cross-references Interchanges (e.g., 72131SC001) for the same application.

Common Issues It Can Address

  • Incorrect cabin temperature blend
  • Airflow stuck on one temperature setting
  • HVAC door movement that is slow or inconsistent
  • Loss of proper dual zone climate control function
  • Clicking or binding from the actuator area

Installation Notes and Tips

Verify the vehicle has dual zone climate control before ordering. Match the connector style, mounting ear layout, and linkage type to the original unit before installation. Confirm the part number 73799 against the removed actuator and the vehicle’s HVAC configuration to ensure the correct replacement.

Quality Assurance

Four Seasons states that its products are engineered and tested for years of trouble-free operation, supported by more than 50 years of mobile A/C experience.
