Here's how it works:
* Engine Heat: The car's engine generates a lot of heat during operation. This heat is captured by a coolant that flows through the engine.
* Radiator: The coolant then flows through a radiator, where it cools down.
* Heater Core: A small radiator called the heater core is connected to the main cooling system.
* Fan: A fan blows air across the heater core, which warms the air.
* Vent: The warm air is then directed into the cabin through vents.
The electric fan and the water pump that circulates the coolant are powered by the car's electrical system.
While the heat source is the engine, the heater itself uses electricity to move the air and direct it into the cabin.
