Automotive heating systems are designed to keep the interior of a vehicle warm during cold weather. They typically use heat generated by the engine, which is transferred to the cabin through a series of ducts and vents. A component called the heater core plays a crucial role, acting like a small radiator that warms the air as it passes through. These systems often include a thermostat to regulate temperature and a blower motor to circulate warm air. Drivers can control the heat output using the climate control settings, allowing for a comfortable driving experience regardless of outside temperatures.
