When you're dealing with heater core problems, it's best to have your vehicle inspected by a professional since this component can be difficult to access (located deep behind your dash on most cars) and messy to fix.

In some vehicles, a valve opens up and allows hot coolant to flow to the heater core when you turn on the heat.
