Heater problem
2004 Ford F250 V8 Four Wheel Drive Automatic 67,000 miles

My heater blows cold air when parked, but blows warmer when the vehicle is moving.

Are you low on coolant? If not you might have a air bubble in the coolins system, let the truck heat up to normal temp. You should have at least 1 bleeder valve. (By the thermostat, water pump, or on one of the lines from the heater core) open one or all the bleeder you find. They should spit a steady stream. So bleed untill it does, might have to close them shut off the truck let it cool and repeat. Hope it helps
