What to Do When the Car Windows Fog Up in the Rain?

On rainy days, you can use the air conditioning system to defog the car windows. Here are the relevant instructions for defogging: 1. Manual air conditioning: Turn on the front window defogging mode, then set the fan speed to maximum, turn on the A/C switch, and adjust the temperature to the lowest. The fog on the windows will be eliminated shortly. 2. Some car models are equipped with rear window electric heating and external rearview mirrors. Simply click the switch to turn them on, and the fog will be eliminated in about a minute. 3. Automatic air conditioning: Generally, you just need to press the one-touch defrost button. After pressing it, the air volume will automatically turn to maximum and the external circulation will be activated, which is both practical and convenient. 4. In winter, you can use the heating system to defog. If the car has just been started, do not turn on the air conditioning temporarily. Wait until the engine has been preheated for a few minutes and the water temperature rises. Then start the heating, set the air volume to maximum, and turn on the front window defogging mode. The fog will disappear in a few minutes.
Driving with foggy car windows on rainy days is indeed annoying. Having driven for over a decade, I always use the air conditioning to solve this problem. Set the AC to blow cold or warm air towards the windshield, as the system quickly dehumidifies and clears the fog. If the effect is slow, slightly open a window to allow air circulation, but not too much to avoid rain getting inside. Avoid placing wet umbrellas or damp items in the car, and keeping the windows clean is crucial. Using a specialized anti-fog agent to wipe the glass can prevent fogging. Safety comes first—fog obstructing your view can easily lead to accidents, so address it promptly. In heavy rain, it’s best to find a safe spot to stop and adjust rather than wiping the windows while driving, which is too dangerous. Developing a habit of regularly cleaning your windows can significantly reduce this hassle.
