How to Deal with Fogging on the Corolla Windshield?
3 Answers
Turn on the car's external air circulation, press the front and rear defogging buttons, and use warm air to defog. Defogging methods: Before starting the car, wipe the external water fog on the car windows with a towel. After wiping the external glass with the towel, start the car, turn on the air conditioning, set the air conditioning to the warm air mode, adjust to a higher temperature with red hot air, turn on the external air circulation, press the front and rear defogging buttons, and use warm air to defog. Manual air conditioning defogging: For manual air conditioning, turn the air direction adjustment knob to the defrost and defog mode. For automatic air conditioning, there is an independent defog button. When defogging is activated, the dehumidification function works and the fan speed increases. If the internal air circulation mode is in use, set the internal air circulation mode button to external circulation. Increasing the airflow and raising the temperature can quickly defog the windshield and front side windows. When defogging the windshield, pressing the defog button again can return to the previous mode.
When encountering fog on the Corolla windshield while driving, I first check if the air conditioning system is functioning properly. The Corolla's defogging button is very practical—just press it to automatically blow cold or warm air for quick results. Remember to switch to the external circulation mode to let the humidity inside the car dissipate; otherwise, the fog will only accumulate more. I regularly clean the interior of the glass to avoid oil residue causing fogging. This issue is most common in winter or rainy weather, as fog severely obstructs vision and increases the risk of rear-end collisions. Therefore, it must be addressed immediately upon discovery—don't tough it out. If the air conditioning isn't working, cracking the window for ventilation is a makeshift solution—though it might be chilly, safety comes first. For long-term prevention, avoid leaving wet clothes or food in the car to reduce humidity. In short, safety is the top priority—don't delay small issues.
When the windshield of my Corolla fogs up, my first instinct is to turn on the air conditioning to defog. I switch to defrost mode, increase the fan speed, and the fog clears up quickly. While driving in cold weather, I use warm air; in summer, I use cold air—it's efficient and hassle-free. Windshield fogging is mainly caused by condensation due to temperature differences, especially when the interior humidity is high. In daily use, I avoid eating hot meals or drinking hot tea with the windows closed to minimize moisture sources. For long trips, I keep a small defogging spray handy—just a quick wipe does the trick, and it's cheap and convenient. When cleaning the glass, I use regular cleaner and a microfiber cloth to remove grease, which helps prevent fogging. Safety-wise, fogged-up windows severely obstruct visibility, so I always pull over safely before dealing with it. I make it a habit to check the AC system regularly and get it fixed if anything seems off. This way, I drive with more peace of mind.
