Product Details

The Four Seasons Air Door Actuator line focuses on replacement components for HVAC door control functions, including recirculation and blend-style air doors. This Four Seasons 73323 actuator is specified for 1998-2002 Lincoln Town Car models and is identified by its male linkage, 4-ear mounting pattern, and 6-pin terminal configuration.

This part cross-references Ford OE-style numbers such as F8VZ19E616AB and YW1Z19E616AA for the same application.

Common Issues This Part Can Address

• Loss of proper cabin air control in a Lincoln Town Car

Installation Notes

Verify the original actuator’s linkage style, mounting ear layout, and terminal pin count before installation. On 1998-2002 Lincoln Town Car HVAC systems, confirm the replacement matches the existing door linkage and connector configuration so the actuator aligns correctly with the air door shaft. Compare the old unit to Four Seasons 73323 before final assembly.
