Four Seasons 73328 HVAC Blend Door Actuator

Four Seasons 73328 Air Door Actuator

Four Seasons 73328 is an HVAC blend door actuator for the air door system in select Mitsubishi Galant models. It is built with an arm-style door linkage, 4 mounting ears, and a 5-terminal pin layout to match the original control interface.

Compatible with 1999-2003 Mitsubishi Galant, this Four Seasons Air Door Actuator supports precise movement of the HVAC air door for temperature and airflow control. The Four Seasons Air Door Actuator line is focused on replacement components for heating and air conditioning systems, and part number 73328 follows that application-specific approach.

Installation Notes and Tips

Verify the connector style, mounting ear layout, and linkage type before installation. On 1999-2003 Mitsubishi Galant HVAC systems, confirm the replacement actuator matches the original 5-pin configuration and arm linkage so the door movement aligns correctly after installation. Compare the removed unit to part number 73328 before final assembly.
