The Blend Air Door Actuator has failed. I probably change 30 a year on our fleet of Crown Vics. Unfortunately, it's very difficult to get to.

Just blows hot air usually out the heater ducts or defroster vents. has the dual zone climate control wish I didn't now! but no matter what I set it to. It blows hot
