Installation Notes and Tips

Verify the vehicle year, make, model, and actuator position before ordering. Match the female linkage, 5-pin connector, and listed application notes such as Main, Left, Right, Panel, or No. 2 to the original part. On Lexus LX570 and Toyota Land Cruiser applications, confirm whether the replacement is for the mode door or recirculation door function.

After installation, cycle the HVAC controls to confirm the door moves through all commanded positions and that airflow changes correctly. If the system has stored HVAC-related faults, clear codes and recheck operation after the actuator is installed.
