Needs the air con gas replaced

SOURCE: the truck 2005 ford 350 the heat is not working is blowing cold air

Check for correct coolant mixture. Also you could have a thermostat that is stuck completely open causing it to flow straight threw the engine block, cylinder heads, heater core, an radiator without stopping long enough to heat the coolant up to provide cab heat. It could also be a clogged heater core. Or a blend door on the HVAC box that is not allowing the heater core door to open. Hope this helps.

I doubt it's a heater core.
first look in the radiator and make sure your coolant is full.
not just in the overflow bottle. a bad radiator cap may not allow coolant to refill the radiator . so the radiator can be low and you still have a full overflow bottle

so refill everything and drive it a few miles and see if your heat comes back.
