No Heat

Got a heating issue I need help with. The fan blows cold air. All the time. When you turn the knob to hot there's no change in temperature. I have replaced the thermostat and the control unit. Didn't fix the problem. It's too cold for this mess.

Blend door actuator could be the culprit? Thoughts?
Mine keep trapping air at the top hose on the heater core so I put a heater hose connection with a bleeder valve on it . [ from Z-1 ] I also replaced the actuator [card] as it would make a clicking sound from not fully closing but you should feel a little heat from there ..
