I have a 2007 Ford Expedition, the very back vent will only blow cold air, Why?
I have a front control and a back control button for the vents, when I turn the back vent
own for heat it blows hard and only cold air. However, I makes this loud clicking noise at
times. Advise please
It is the actuator that is making that clicking noise. Very easy to replace it is located in the back seat right panel where the cup holder is. Just remove four screws and take it out. They say you need the genuine ford part which was priced at about $85.
