Detailed Description

The Four Seasons 73624 is an HVAC recirculation door actuator used to move the air door inside the climate control housing. When the actuator fails, the system may lose the ability to switch between fresh air and recirculated cabin air, which can affect comfort and HVAC performance. This replacement is built to match the listed Subaru fitment and uses the specified arm linkage, mounting ear layout, and 3-pin terminal design for proper integration.

This part cross-references 72131AL00A and ACT1951IM for the same application. If you are searching for a 2015-2019 Subaru Legacy HVAC recirculation door actuator or a 2015-2019 Subaru Outback HVAC air door actuator, Four Seasons 73624 is the cataloged replacement to review.

What It Helps Fix

• Recirculation door not changing position
• HVAC airflow stuck on fresh air or recirculation
• Clicking or inconsistent actuator movement behind the dash
• Loss of cabin air control through the HVAC system
• Climate control response issues tied to the air door actuator

Installation Notes and Tips

Verify the connector style, mounting ear layout, and linkage type before installation. Access is typically through the HVAC housing, so confirm the actuator location on the vehicle and compare the old unit to the new Four Seasons 73624 before final assembly. After installation, cycle the HVAC controls to confirm the recirculation door moves smoothly through its full range.

Quality Assurance
