Take back precise control of your cabin temperature and airflow with the Four Seasons HVAC Air Door Actuator 73515, an HVAC blend door actuator that drives the internal air door to set the hot/cold blend and recirculation. It's a direct-fit replacement for a wide range of Toyota and Lexus applications, including the 2006-2012 Toyota RAV4, 2020-2024 Toyota Highlander, and 2021-2024 Toyota Sienna — see the "Vehicles it fits" section for the full list. Cataloged for the LEFT, MAIN, and AUXILIARY positions.
- Includes as applicable: lever arm, gear, cam gear hardware, and linkage.
- Quality internals: motor, drive gears, electronics, and connections.
- Validated: tested for function, durability, and longevity.
- Built to OE-level fit and function so it drops into the listed applications.
If a stuck temperature setting, a door that won't change modes, or a clicking/knocking behind the dash traces back to a failed actuator, this replaces it. Diagnose the cause before replacing, since HVAC faults can stem from the door, linkage, or control head.
