Four Seasons 73517 HVAC Recirculation Door Actuator

Four Seasons 73517 Air Door Actuator Overview

Four Seasons 73517 is an HVAC recirculation door actuator built for vehicles that use a 5-terminal, female-door-linkage design with a 4-ear mounting pattern. It helps control the air door position inside the climate system, supporting proper cabin airflow management in select Lexus and Toyota applications.

The Four Seasons Air Door Actuator line focuses on direct-fit HVAC control components for recirculation and blend-door operation. This 73517 actuator is a practical replacement when the original unit no longer moves the door correctly or responds consistently to HVAC commands.

Installation Notes and Tips

Verify the connector style, terminal count, linkage type, and mounting-ear layout before installation. On vehicles such as the Toyota Corolla, Prius, Prius Prime, Prius C, and Lexus UX models, confirm the actuator location and the door designation in the HVAC case so the replacement matches the original unit.

After installation, cycle the ignition and HVAC controls to allow the system to relearn door positions if required by the vehicle. If the original actuator failed due to a binding door, inspect the HVAC door movement before installing the replacement.
