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.

Ok where is the blend air door located on this 2000 olds silhouette van

Near heater core in the HVAC box.

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.
