There is no doubt that the Fiesta's interior is cozy and comfortable. The Interior section provides maintenance and repair work that you can do yourself, such as troubleshooting an electric window or replacing an interior light bulb. Keep in mind that regular interior maintenance will significantly increase the value of your car when you sell it.
Heating and ventilation
Fig. 16.1. Location of ventilation and heating system elements under the instrument panel
Part of the air flow around the car enters the passenger compartment in front of the windshield. Fresh air passes through a dust (and pollen) filter and a fan. To keep the car windows clean even in humid weather, they are forcibly blown with air during the trip. With the deflectors and windows closed, forced ventilation ensures constant air circulation. The position of the air guide flaps and deflectors allows you to set different modes of ventilation or heating the passenger compartment. Fresh outside air passes through the aluminum fins of the heater radiator, located under the dashboard, and heats up to the required temperature (Fig. 16.1). Without a heater blower fan, the efficiency of ventilation depends on the speed of the car, so when driving short distances and in city mode, turn the fan to position "1" or "2"; in this case, regardless of the speed, the air flow is distributed faster in the car interior. Air circulation is maintained by a four-speed fan located in front of the heater radiator.

The air conditioning system removes excess heat and moisture from the passenger compartment. The refrigerant, circulating as a liquid in the high-pressure section of the system, evaporates and turns into a gas in the low-pressure section. As the gas expands, cooling occurs, accompanied by the removal of heat from the air supplied to the passenger compartment by the fan, and a decrease in its temperature. Then, as the refrigerant passes through the condenser, it releases the absorbed heat to the surrounding air. The heat removal cycle continues indefinitely as the refrigerant circulates in a closed circuit. Moisture is removed from the air supplied to the passenger compartment through air flaps and deflectors due to condensation on the evaporator of the refrigeration chamber (Fig. 16.2).
