What It Helps Fix

• HVAC doors that do not change position when the controls are adjusted
• Airflow stuck on one vent setting, such as floor, panel, or recirculation
• Temperature or airflow distribution problems caused by a failed actuator
• Clicking or inconsistent movement from the HVAC door mechanism
• Loss of proper recirculation door response in the climate system

Installation Notes and Tips

Verify the connector style, 5-terminal pin layout, female linkage, and mounting ear configuration before installation. Confirm the vehicle position listed for your application, since this actuator is used in left main, right main, auxiliary, front, and floor locations depending on the model. For best results, compare the original part number and actuator shape to the removed unit before replacement.
