1 Answers
Buick car defogging and defrosting buttons are the same button, located on the air conditioning panel. Choosing cold or warm air for car defogging: Both cold and warm air can be used for defogging inside the car, the difference lies in the speed of defogging. You can choose according to your own situation. Cold air defogging is faster and relatively safer, while warm air defogging takes longer, but once the fog is dried by warm air, it can remain fog-free for a long time. If the driver needs to drive for a long time, it is recommended to use warm air defogging. Initially, higher temperature air can be used, and once the fog gradually disappears, the temperature can be lowered to about 21 degrees. Although using warm air may initially increase the fog slightly, the subsequent effect will be much better. If the driving time is short, cold air defogging can be used. Using internal or external circulation for defogging in rainy days: During seasons with heavy rain, if the temperature difference between the inside and outside of the car is large or the humidity is high, it is easy to cause the car windows to fog up. Whether to use internal or external circulation for defogging in rainy days depends on the specific situation. If cooling is used for defogging in summer, the driver can adjust the air circulation mode to internal circulation to reduce air humidity. If warm air is used for defogging in winter, the driver can first adjust the air circulation mode to external circulation to reduce the temperature difference between the inside and outside of the car, wait for a few minutes, and then switch to internal circulation mode. However, in special circumstances such as traffic jams or high dust, it is recommended to use internal circulation mode.
