Question about Ford F-150
Electric or vacuum operated? My F-150 manual doesn't say. Can you replace the actuator if it's electric? If vacuum it still may need replacing or the hose has got a vacuum leak somewhere.

SOURCE: heater core replacement
This is a really easy job, disconnect the heater hoses at the firewall, go inside the truck on the passenger side there is a plastic panel/cover over the core, 6 bolts/screws I think, remove the cover pull the core, tops 1 hour, as job at work I did them in 20 minutes.

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.
Flush the heater core 2-3 times, and if the obstruction does not clear, a new heater core is required.

the heater core hoses are under the hood on passenger side u can disconnect them from heater core and connect them together with a fitting that will withstand high tempature about 200 degrees ask local hardware store or autoparts store for fitting i think the size is 5/8 and the fitting only has to be 3 inches in length this will bypass heater core when ur done top of fluid and check for leaks with car running and warm

if the air is definatly being blown through the heater core , then the core is blocked.if there is no hot coolant passing through the core then ------no warm air ---give it a good look see if you can see the deflector guiding the blown air is going far enough to send majority of air through heater good luck
