The work of the heater core is to regulate the temperature within the car. When this component breaks down, your car is left without any heat as your antifreeze stops flowing.
Where is the heater core located in a car?
The heater core is similar to the radiator located in the vehicle’s cooling system. The blower motor forces air through the core and into the air duct system allowing temperature controls which enable defrost floor and front vent modes.
