How to Solve Fogging on the Front Windshield?
3 Answers
Solutions for fogging on the front windshield: 1. Cold air defogging: The principle is similar to convection defogging, keeping the inside and outside temperatures the same so that fog does not adhere to the glass; 2. Hot air defogging: Uses the principle of evaporating fog with hot air, which takes less time than cold air defogging; 3. Physical defogging: Use the wiper to clear fog on the outside of the front windshield, and roll the window up and down to clear fog on the side glass. The defogging function has two buttons, for the front and rear respectively. The front windshield defogging icon is fan-shaped, while the rear windshield defogging icon is rectangular. Power windows refer to windows that can be automatically raised or lowered using power. The driver or passenger operates a switch to connect the window lift motor circuit, which generates power to drive a series of mechanical transmissions, allowing the window glass to be raised or lowered as needed.
Foggy windows can be really annoying. After years of driving, I've summarized a few tricks. The primary method is to turn on the fan and direct it at the front window while driving. Using the air conditioner with cold air quickly absorbs moisture, while hot air also works but takes longer. In winter, the temperature difference is greater, making fogging more likely. Warm up the engine before driving and then turn on the hot air to avoid sudden condensation. Avoid eating in the car or placing wet items daily, and keep umbrellas properly stored to reduce moisture. Clean the inside of the windows regularly with a microfiber cloth, ensuring no oil stains remain. I've also tried applying diluted shampoo as a temporary anti-fog layer—it's cheap and effective. If fogging becomes severe, slow down and pull over to handle it safely; never take risks. I recommend keeping an anti-fog spray in the car, which costs just a few dozen yuan online. This small issue can affect visibility, so timely handling ensures safety.
To prevent window fogging, I prioritize prevention. Daily habits include maintaining interior cleanliness, such as avoiding open drinks or damp clothes. Before each drive, I run the air conditioning on external circulation for a few minutes to reduce humidity—a simple routine that saves hassle. Weekly, I clean windows with glass cleaner to remove grime. Applying anti-fog film provides long-term protection; it’s stylish and available on Taobao. Silica gel desiccant bags inside the car absorb moisture reliably. On rainy days, cracking windows slightly balances temperature differences. In emergencies, the defrost button delivers instant airflow. Don’t overlook AC filter replacements during maintenance to ensure proper system drainage. Long-term, these small steps cut 90% of issues, keeping me worry-free.
