No heat, auto control system...

Engine hot, all controls responsive, but no heat.
Dual-zone digital climate control.

Temp never changes no matter what I select with the knobs.
I have changed out the airaitor, done complete recallibration procedure, and checked that the heater core hoses are indeed hot.

Are the temperature actuator motors known to be such an issue? It would be surprising to me that, exactly and only, two motors are bad with all else functioning.

Also, if not using the 'auto' feature (which I still dont know what it does), does it still use all billion sensors?

Any help appreciated!
