The door actuator that should move when you turn the heat dial does not move. There is warm water going to the heater core. I searched the Internet and I think I'm looking at the door actuator assy, it's white and has a lever that points down at an angle which I think is supposed to move with the dial. Am I on the right path to resolving this issue? Thanks!

Possibly so if you are seeing a motor attached at the plenum where the door sits. Happily it seems as if this motor does not require dash removal, as it does on many other vehicles.
