How to Deal with Fogging Inside the Car When Using Air Conditioning in Summer?

Spray a small amount of defogging agent on the car windows and wipe it clean to form a thin transparent protective film on the glass. You can open a small gap in the car window to allow air convection between the inside and outside of the car, balancing the temperature difference inside and outside the car, which can also help prevent fogging. Turn on the warm air conditioning and use the warm air to blow hot air onto the glass, quickly raising the temperature of the front glass to eliminate fogging.
It's really annoying when the car fogs up with the AC on in summer. From my driving experience, I've figured out solutions. Simply press the defog button or turn on the AC compressor (A/C button) to quickly dehumidify and cool down. Set the temperature around 22°C for optimal comfort—not too low. Always direct the airflow toward the windshield. Using recirculation mode is crucial to prevent outside humidity from entering. If no buttons are available temporarily, blasting high airflow at the glass can help. Avoid leaving damp items like umbrellas or sports shoes inside. For long-term prevention, regularly clean the AC system and filters, and placing a desiccant pack also works. Remember to address fogging immediately for safe driving—don’t delay.
Common issues with fogging inside the car when using air conditioning in summer are frequently encountered. It is recommended to immediately switch the air conditioning mode to the defogging function or manually adjust the airflow direction to maximum towards the front window, with the temperature controlled between 20 to 25 degrees Celsius. Use the internal circulation mode to prevent external humidity from entering, and check the car for any damp items that should be removed. If the air conditioning filter is dirty, it should be replaced promptly to avoid poor cooling and dehumidification effects. For temporary emergencies, opening the car window slightly can help circulate air. For long-term maintenance, it is advisable to use anti-fog spray on the glass and service the air conditioning system annually to maintain a dry environment for safer driving.
It's really annoying when the car windows fog up as soon as the AC is turned on in summer. Press the defogger button immediately or adjust the air vents to blow towards the windshield for better cooling and dehumidification. Set the temperature to normal, not too low. Turn on the internal circulation to reduce external moisture and avoid keeping wet items like towels in the car. Replace the dirty AC filter promptly and maintain cleanliness regularly to prevent fogging. Driving safety comes first and should be taken seriously.
