If both heater hoses comming from the heater core are hot, the blend door is NOT moving, if the inlet hose is hot but outlet is cold, the heater core needs more flushing, or replacement. if both hoses are cold, check antifreeze level and thermostat, also rarley but known to happen is the impeller blades on the water pump disolve over time and may not be pumping enough.
