Your hot cold adjustment moves a flapper at the discharge of the fan. If the vacuum is not present, it will not move when you change the temperature knob control. If it is blowing cold air, that is probably your problem. Also the control knob may be bad not sending a signal to cause the flapper to move. No power to control knob, or power leaving control knob to cause flapper to move.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
