It transfers movement from the servo linkage to the defroster flap, allowing the system to direct airflow toward the windshield when commanded.\u003c\/p\u003e\u003cp\u003eThe lever is identified by its red color and its specific hub and linkage geometry. Several similar levers are used around the HVAC housing.
