Your car’s heating system provides heat to the passenger compartment of the vehicle. It is connected to the cooling system and uses the same fluid (coolant) that keeps the engine cool to heat the engine. Once the engine has reached operating temperature, the thermostat opens to allow the coolant to flow into the heater core which is located inside the passenger compartment of the vehicle. A heater control valve will open or close the flow of coolant to the heater core depending on the position of the “warm to cold” selection on the heater control assembly. The blower motor powers a fan which blows air across the warm heater core and that provides heat to the interior of the vehicle.
The air is forced through a duct system that routes the heat through the various vents in the car. The system uses a series of blend doors, operated by electrical and vacuum controlled actuators to direct the flow of air to the top of the dashboard (for defrost), directly towards the passengers in the car, or towards the floor to provide heat for the feet. If you are directing the flow of heat to your face or feet, but not feeling a change, you may have a problem with one of the actuators that control the blend doors.
Here is an overview of how the heating system works:
