The heater control valve is normally attached to the heater hose-also check the air blend door-Have you checked the thermostat?

You have a blend air door on this vehicle, not a heater control valve.

No heater control valve. Blend door only. Is it full of coolant, is the thermostat stuck, air in system, heater core clogged. You need to do a lot more checks.
