I have checked:
Coolant overflow is at normal level.
Both the inlet and outlet of the heater core are hot at the firewall.
The engine is not overheating or underheating.
The fan is operating normal.
The mixing door that opens and closes above the cabin filter is operational.
There is no heat at any setting (vent, defrost, floor)

I don't know what to check next.??
Any thoughts are greatly appreciated
sounds like the blend door actuator is bad. the door you are seeing move is the fresh air door. the blend door which controls the heat will be inside the heater box, you wont be able to see it.
