Product Details
Four Seasons 73331 is an HVAC air door actuator used to move the recirculation door inside the heating and air conditioning system. The arm linkage transfers actuator movement to the door mechanism, helping the system switch between fresh air and recirculated cabin air.

Installation Notes
Confirm the original actuator uses an arm linkage, 2-pin connector, and 5-ear mounting pattern before replacement. Access is typically through the HVAC housing, so compare the old unit to the new part before securing it in place. After installation, cycle the climate controls to verify smooth recirculation door movement and proper operation.
