sounds to me like the blend door is jammed, or the actuator for it is bad.
the actuator for the temperature control is up above the vent for the drivers side footwell (its up there a ways, not right above the gas pedal according to the FSM, the one right by the gas pedal is the mode door actuator, so for foot/face/defrost controls)

I notice you said the inlet hose is hot, however you said nothing about the return hose? The return is on the intake manifold, the pressure side is on the water pump. If both sides are hot then I would suspect a blend door. If they are slightly different or largely different I would suggest you flush the heater core with a house hose both backward and forward flush then reassemble. Flush at full blast.
