The rotary heater control knob on the center of the dash attaches to a cable that controls the heater control valve or heater control flat behind the dash, which allows coolant flow through the heater core. You don't have much room to see anything behind the dash without some partial disassemble but I would imagine the cable is detached at one end or the door is stuck and not being operated.
