Why does my car heater keep blowing hot air?
Hot coolant passing through the heater core gives off heat before returning to the engine cooling circuit. The fan for the vehicle’s ventilation system forces air through the heater core to transfer heat from the coolant to the cabin air, which is directed into the vehicle through the vents.
Where is the heater located on a Chevy Blazer?
The cabin heater in your vehicle produces heat from a heater core. The heater core is a small radiator, located under the dashboard of the vehicle and 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.
