Installation Notes and Tips

Verify the vehicle’s HVAC option code and actuator position before ordering, since fitment varies by air inlet, temperature, mode, main, left main, right main, upper main, lower main, and auxiliary locations. Access is typically through the HVAC case or dash area, so compare the original connector and mounting style before installation. After replacement, recalibrate the climate control system if the vehicle service procedure requires it.
