No cold air from front vents?

2000 Ford Expedition:

A/C works and blows cold air out but only blows out of the defroster not the front vents.
You either have a bad control, or motor running the air direction door in the front HVAC unit, or a door that is stuck.
The front and rear units are totally separate.
The door directs where the air, cold or hot, should come out, whether it is panel vents, floor, defrost, or any combination of those.
This door and motor are located inside the heater box which usually requires a lot of the vehicle dash assembly to be taken apart to get to these parts.
