I had the same problem and ironically found it by not looking for it there is a vacuum line that runs to the passanger side of the truck up by the radiator mit and weather check and leaking badly replaced it and boom my heat was back come to find out ford ran a vacuum control valve out the intack you can follow one of your heater core lines back and find it it you have a vacuum leak its not opening the vavle. Giving you little or no heat! Just somthing to look for!

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
