    It could be your heater core. You can try checking for proper coolant flow through your heater core. When the engine is warmed up and the heater set to hot, CAREFULLY check the inlet and outlet heater hoses, they should BOTH be hot to the touch. If they are not you may have a coolant flow problem which is causing your lack of heat output. Be sure to check all related cooling system components before deciding the fault is a plugged heater core.
