Product Details

This Four Seasons HVAC recirculation door actuator helps control the movement of the air door inside the heating and air conditioning housing. In a Toyota Prius C, the actuator works with the climate system to direct cabin air flow between fresh air and recirculated air settings. Four Seasons 73716 is built from the company’s mobile A/C experience and is intended for long-term service in HVAC repair applications. This part cross-references Monroe Shocks & Struts (e.g., ACT2066IM) for the same application.
