Do You Need to Turn on the A/C for Car Cooling?

[VonTravis]

To activate the cold air in a car, you must turn on the A/C switch; otherwise, the air conditioning system will only operate the blower, delivering air at normal temperature. Here are specific details about using the car's cold air: 1. On hot summer days, when you press the A/C button, adjust the temperature control to the blue position. For automatic air conditioning, set a desired temperature and press the AUTO button, and the system will automatically regulate the cabin temperature. 2. To quickly lower the temperature inside the car in summer, direct the air vents slightly upward. Utilizing the principle that hot air rises and cold air sinks, the descending cold air can rapidly cool the interior. 3. After starting the vehicle, allow the engine to warm up first. Once the engine temperature gauge reaches the midpoint, turn on the heating and set the air circulation to external mode to expel the cold air from the cabin. After 2-3 minutes, switch the air circulation to internal mode.
