Heat works sometimes and sometimes it only blows luke warm air. Heater core is not blocked. Has a new water pump and thermostat. Check engine lite comes on intermittently, sometimes not for days though. When the heat does not work, one hose will be ice cold and the other hot, on both the radiator and the heater core hoses. today it worked fine.
