Backlight conditioning gas

This situation may be caused by the design of automobile air conditioning display screen. On the air conditioning control panel of some models, when the set temperature is lower than the indoor temperature, the numbers will be displayed on the display screen, but when the set temperature is higher than the indoor temperature, the numbers will not be displayed, but the air conditioner operates normally.

This design is to prevent drivers from paying too much attention to numbers, thus distracting drivers and making drivers more focused on driving. In addition, this design can also reduce glare and visual interference caused by high brightness of the display screen in low temperature environment.

Therefore, if your car air conditioner is running normally and there are no numbers on the display screen when the temperature is high, it is probably a design reason, not a fault. However, if you feel that the air conditioner is not working normally or there are other abnormal conditions, it is recommended to go to a regular automobile maintenance center as soon as possible to ensure the safe and normal operation of the vehicle.
