Installation Notes and Tips

Verify the vehicle year, make, model, and arm-style linkage before ordering. Confirm the 5-pin connector and 4-ear mounting layout match the original actuator. On Toyota and Lexus HVAC systems, access is often limited, so compare the original unit’s orientation and linkage position before removal. After installation, cycle the HVAC controls to confirm the recirculation door responds correctly.
