Installation Notes and Tips

Verify the vehicle year, make, model, and HVAC position before ordering. Some listed applications note that recalibration or programming with a scan tool may be required after installation, especially on newer Chrysler, Dodge, Nissan Frontier, and Toyota Yaris applications. Confirm the connector style, mounting ear layout, and linkage type against the original unit to ensure the correct replacement.

For dual-zone systems and vehicles with left, right, main, or auxiliary HVAC positions, match the exact position shown in the fitment data. This is especially important on Chrysler 300, Dodge Charger, Dodge Grand Caravan, and Ram ProMaster applications where multiple actuator locations may be used.
