Where is the heater core located?
A heater core is a small radiator located under the dashboard of the vehicle, and it consists of conductive aluminium or brass tubing with cooling fins to increase surface area. Hot coolant passing through the heater core gives off heat before returning to the engine cooling circuit.
Why do heater cores go bad?
How does a heater core go bad? There are multiple reasons a car's heater core could not be working properly. One reason could be due to clogging, as the coolant could become contaminated if it's not regularly flushed out.

How do you test a heater core?
To measure the thickness of the core, you measure from the outside of the fin to outside on the other side of that fin. Please see diagram below. Radiator cores come in a vast range of thickness ranging from 16mm to 73mm for most automotive cars, light commercial light trucks and 4WD.
What causes heater in car not to work?
Most Common Causes of Car Heater Malfunction
The heater switching system might be faulty. The cabin air filter might be choked, restricting the airflow through the heater core. The thermostat valve might not be working right. The heater core might be clogged.
