How to ventilate when you can't open the windows while driving in the rain?

[OCarmen]

When you can't open the windows while driving in the rain, you can turn on the fan or open the sunroof. Here are the specific methods: 1. Turn on the fan: Switch to the cold air position and turn on the fan, but do not press the AC button. Select the external circulation mode, which allows fresh outside air to directly enter the car. 2. Open the sunroof: If your car has a sunroof, you can open it slightly. When driving at high speeds, opening the sunroof creates negative pressure on the roof, which helps draw out stale air from the car. While driving forward, due to headwind, a small amount of air will enter the car through the air conditioning ducts, generally not causing oxygen deprivation. However, if the car is well-sealed and the occupants are not in good health, prolonged driving under such conditions may inadvertently lead to feelings of stuffiness and fatigue. If you feel the air is fresher after getting out of the car after a long drive, it actually indicates oxygen deprivation.
