How to Solve the Fogging Issue on the Front Windshield of the Lamando?
4 Answers
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 setting. The fog on the windshield will disappear. Opening the windows can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken the conditions for fog formation. This method seems very economical. The principle is to use surfactants to leave a protective film on the glass surface, altering the surface tension of water molecules, causing fog droplets to coalesce into larger water droplets. Using a towel to wipe off the fog can only be done when the vehicle is stationary. It is not advisable to wipe the windshield while driving, as it can distract attention.
Having driven Volkswagen cars for years, I often encounter fogging on the windshield of my Lamando. My usual approach is to first press the front defrost button on the AC panel, which has a fan icon. Activating it automatically adjusts the fan speed and temperature to clear the fog. If the AC feels too cold, I turn the temperature knob to the warm air setting, around 25°C, directing the vents straight at the windshield. A higher fan speed works faster, but I avoid the highest setting to minimize noise. When humidity is high, I switch to external air circulation to dry the glass more quickly. Regularly cleaning oil and dust off the glass also helps prevent fog from recurring. In winter, with large temperature differences, I activate this function right after starting the car as a preventive measure—it clears up in just a few minutes. Note: If the system isn’t working properly, check for low refrigerant or a clogged filter, and visit a 4S店 promptly to avoid compromising visibility safety.
I'm a new driver, and I really hate it when my Lamando fogs up. I just find the defog button on the center console, which looks like a wavy arrow, and press it to activate the defog mode. The wind blows hard on the windshield, and the fog clears up in no time. I usually set the temperature to medium warm air, which feels more comfortable. If there are many people in the car breathing, cracking the window a bit helps reduce the humidity. I always keep a clean cloth handy to wipe the glass and avoid leaving fingerprints. If the automatic air conditioning settings get messed up, I often switch back to AUTO mode to let it defog automatically—it's hassle-free. Don't panic when the windows fog up; stay calm and handle it smoothly for a clear view.
I found that fogging occurs because the moisture inside the car condenses on the cold glass. The solution is simple: turn on the air conditioning defogging function to let dry cold or warm air blow towards the glass surface to evaporate the water droplets. The Lamando has a dedicated front window defrost mode; pressing the button will automatically adjust the air vent direction to dehumidify. Combining this with the external circulation mode is more effective, as it introduces fresh air to reduce the temperature difference inside and outside the car. Keeping the glass clean also has a preventive effect, as accumulated dust layers are prone to fogging. Observe the changes for a few seconds during operation, and turn it off to save power once visibility is clear. This is how the humidity effect is physically resolved.
