Assuming the coolant level is full, it could be a stuck open thermostat or a plugged up heater core or the temp blend door actuator is broken. Run the engine for 10 minutes or more then feel with your hands both heater hoses, if they are both only luke warm change the thermostat. If one is hot and the other is luke warm flush the heater core. If they are both hot I would suspect the temp blend door actuator isn't working.
