What does 'rear' on the air conditioner mean?

'Rear' on the air conditioner is the button to activate the rear air conditioning in a car. Pressing it can remove fog from the rear windshield. However, many car models omit the English word 'rear' and simply use an icon. Some more high-end cars have very thin copper wires on the rear windshield, which are heating elements. By pressing the 'rear' button, these wires can be heated to defog the glass. The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety.
I usually enjoy exploring various functions while driving, and the 'rear' on the air conditioning refers to the rear air conditioning. In my car, the rear button is used to control the air vents for the rear seating area—simply pressing it turns the rear cooling or heating on or off. This design is particularly useful when there are passengers in the back, such as when traveling with friends. I can adjust the temperature from the front, while they can control it from the rear. The principle is to divert airflow to the rear vents through the air conditioning system, preventing the front from getting too cold while the back remains too hot. Many family cars, like SUVs, have a rear option, and it’s very easy to operate—just press the button and turn the knob to set the fan speed and temperature. I think this feature enhances overall comfort and prevents passengers from complaining, making the journey more enjoyable.
