With the onset of monsoon, car drivers face a common yet dangerous challenge. As soon as the AC is turned on, steam or fog begins to form on the windshield and windows. In the blink of an eye, the view of the road outside becomes obscured. This situation not only makes the driver uncomfortable but also significantly increases the risk of accidents. If you experience this problem during rainy and humid weather, there’s no need to panic. Your car has a button that can eliminate this problem in seconds.
The main reason for steam formation on car windows is the difference in temperature between the inside and outside of the vehicle. When the weather outside is hot, humid, or humid, and you run a chilled AC inside the cabin, the glass is exposed to both temperatures. This causes the moisture in the air to condense and freeze on the outer or inner surfaces of the glass. This is why visibility rapidly decreases during monsoon and extreme cold.
To address this predicament, modern vehicles are equipped with a de-fogger or defroster. As soon as fog appears on the windows, you should press this button on the dashboard. This system focuses airflow directly onto the main windshield, balancing the temperature to instantly brighten the glass. Vehicles often have a separate rear de-fogger for the rear windshield.
If you’ve noticed, there are fine red or brown lines on the rear glass. These aren’t simple designs, but rather heating filaments. As soon as the rear de-fogger is turned on, a mild current flows through these lines, causing them to heat up. This heat instantly evaporates any water and fog accumulated on the glass, allowing clearer visibility of the traffic behind.
For vehicles that don’t have automatic de-foggers or rear filaments, there’s an easier solution. In such a situation, instead of keeping the AC temperature too low, increase it slightly. Turn off the air circulation switch on the AC panel and turn on the “fresh air” mode. If the situation still persists, roll down the car windows slightly. This will equalize the outside and inside temperatures, and the steam will dissipate automatically.
To ensure safe driving, check the windshield wipers and washer fluid before starting your journey. Keep the cabin filter clean so that the de-fogger can blow air efficiently. If fog obscures your view of the road ahead, slow down or stop at a safe place and clean the windows first. Clear and sharp visibility is the key to safe driving during the rainy season.
