Description

The Four Seasons 73644 is an HVAC mode door actuator designed to restore proper airflow control in compatible vehicles. It features an arm-type door linkage for precise operation and three mounting ears for secure installation. The actuator has five terminal pins to ensure reliable electrical connections.

This component is essential for regulating airflow direction, addressing common HVAC issues such as the inability to switch between air modes, inconsistent airflow, or a failure of the system to respond to control inputs.
