With vehicle warmed up and running feel both heater hoses with your hands. If one hose is hot and the other is cold or luke warm, the heater core is plugged. Flushing the heater core should help. If both heater hoses are hot, the temp blend door actuator behind the dash may be broken in which case the entire dash assembly would have to be removed to repair/replace the temp blend door actuator.
