There really isn't a heater control valve. The coolant flows through the heater core at max pressure and temperature is controlled by controlling the amount of air flowing through the heater core. This is the function of the blend door and this is a fairly common failure on Ford trucks. Check heatertreater.net for diagnostic information and suggestions on how to repair the system.
