What to Do When There Is Water on the Inner Side of the Car Windshield?
3 Answers
If there is water on the inner side, you can open the windows or turn on the warm air from the air conditioner. Below is some relevant information about car windshields: 1. Precautions: The windshield must be replaced correctly. To prevent air or water leaks, avoid washing the car for three days, and remove the tape securing the windshield position after three days. Drive smoothly and avoid sudden braking or rapid acceleration. 2. Function: The reflection of passengers inside the car through the front windshield appears above the front of the car, while pedestrians on the road are in front of the car, allowing the driver to distinguish between passengers inside the car and pedestrians on the road. If the car's windshield is placed vertically, it acts like a large flat mirror, reflecting the passengers inside the car in front of the vehicle, which can obstruct the driver's view of pedestrians on the road and easily cause illusions.
A few days ago, while driving my child to school, the inside of the windshield suddenly fogged up with condensation, making it almost impossible to see the road, which really startled me. This situation is quite common in damp and cold weather, where high humidity inside the car combined with temperature differences on the glass causes condensation. I immediately turned on the air conditioning's defogging mode, adjusted the airflow to blow directly onto the windshield area, turned on some warm air to dry the air, and slightly rolled down the windows to let out some moisture. I usually take preventive measures, such as not closing the windows completely for too long when parked, placing a dehumidifying bag in the car to absorb moisture, and cleaning the inside of the glass once a week with a clean cloth and anti-fog spray to reduce water vapor buildup. Safety first—when fogging is severe, always turn on the fog lights, drive slowly, or stop to deal with it.
Having driven for over a decade, fogging is nothing new to me. The first thing after starting the car is activating the defog function—most vehicles have a dedicated AC button to blast high airflow at the windshield. In cold weather, warm air dries it quickly; in summer, AC dehumidifies efficiently. Parking with good ventilation prevents moisture buildup—I clean the inner glass with a slightly damp cloth and vinegar solution, natural and cost-effective. Avoid leaving wet floor mats or clothes inside, and replace AC filters regularly to ensure smooth airflow. The real danger is forcing your way with blurred vision—address it promptly for safety.
