Ford Repair: heater control valve, heater core replacement, heater control valve

Question
I have a 2004 f150 lariat pu and I am looking for the location of the heater control valve8p115

Answer
this one doesn't have a control valve as such heat goes through heater core at all times and is controlled by the blend door opening and closing and demanded by control head-if your blowing cold air and both heater hoses are hot you probably have a bad blend door or actuator. dash has to come out for blend door repair or heater core replacement but i don't see many clogged ford cores.
