Well heres another one for ya HAN. I have no heat in my (believe it or not) "winter car". I have replaced the thermostat with a new one checked coolant levels and fixed a leak in the radiator. But still the temp. gauge doesn't display temp of the engine and NO HEAT COMES OUT!!!

Help me please. Everybody is telling me now that its the heater core, what kind of expense am I looking at here? lOts-O-labOr or is it relatively an "easy" fix...thanks much appreciated as always.
