Four Seasons 73558 HVAC Air Door Actuator

The Four Seasons 73558 is an HVAC air door actuator, also called a blend door actuator or air door motor. It is part of the heating and air conditioning system. The actuator moves an internal door in the HVAC housing. That door controls airflow and the mix of hot and cold air delivered to the cabin.

Key Points:

• HVAC air door actuator replacement part from Four Seasons
• Moves the HVAC air door that directs and blends airflow
• Helps restore control of cabin temperature and air direction when the original actuator has failed
