A heater core in a vehicle takes some of the heat from the coolant and runs it through a heat exchanger. The blower in the car that blows hot air into your car runs through that heat exchanger which heats the air that enters your car.f the heater core in your vehicle goes out, you will not be able  to use your heater or defroster.
