When my truck isnt moving the heat gets warm but when moving it gets cold again. What could be wrong? Ive never changed the antifreeze/ or could it be a fuse or what?

Do you

Never changed coolant? 14 years? Not good.

Could be thermostat, heater core clogged with debris, radiator or blend door motor
