Default heater temp control not working

mazda B4000 4x4; 2008

rotating the temp control knob full to the ccw position (hot) does not change the temp of the air blowing into the cab; I manually held the valve allowing hot flow into the heater core still not heat; also the valve does not change position and there is no vacuum at the valve; the AC is working great
