Keep your Subaru's climate system switching cleanly between fresh outside air and recirculated cabin air with the Four Seasons HVAC Recirculation Door Actuator, MPN 73704. This small electric motor drives the recirculation door inside the HVAC case, positioning the flap in response to your climate control commands. It's a direct-fit replacement for the 2010-2014 Subaru Legacy and 2010-2014 Subaru Outback — see the "Vehicles it fits" section for engine-level coverage.
A recirculation actuator that binds, clicks, or stops responding can leave the mode door stuck, cause weak airflow changes, or trigger a repeating clicking noise behind the dash. If a failed actuator is the cause, this unit replaces it.
- Built to spec: Meets or exceeds OE specifications for fit and function.
- Included components: Ships with lever arm, gear, cam gear, and linkage as applicable.
- Quality internals: Internal motor, drive gears, electronics, and connections.
