For buyers searching for a Mitsubishi Galant HVAC recirculation door actuator, Mitsubishi Eclipse air door actuator, or Mitsubishi Endeavor climate control actuator, this replacement provides a direct-match service part under the Four Seasons 73648 part number.

What It Helps Fix

• Recirculation door stuck in one position
• HVAC airflow that will not switch between fresh air and cabin air
• Clicking or inconsistent actuator movement behind the dash
• Loss of proper climate control response from the recirculation function
• Faulty air door positioning in the HVAC housing

Installation Notes

Verify the connector style, mounting ear layout, and door linkage type before installation. Access is typically through the HVAC housing behind the dash, so compare the original actuator to Four Seasons 73648 before removal. After installation, cycle the HVAC controls to confirm smooth door movement and correct recirculation operation.
