if both hoses are warm, wouldn't that mean coolant is flowing through the heater core? You may have a problem with the vacuum switch on the back of the control head on the dash. There is a (usually) 9 port switch that moves vacuum to all of the doors. The levers will work freely, but just lose function. The usual first sign of this is everything blowing from the floor vent, and slowly moving to the desired position.
