How to Turn on the Defogger for the Front Windshield?

The method to turn on the defogger for the front windshield is: Press the front windshield defogging button, and the air will blow directly onto the glass, effectively removing the fog. A fan-shaped symbol indicates the front window defogger and defroster, while a rectangular symbol indicates the rear window defogger and defroster. The reason for fogging on the glass is simple: it's due to the temperature difference between the inside and outside of the vehicle acting on the windshield. When the temperature inside the cabin is higher than outside, moisture inside the cabin condenses on the inner surface of the windshield, forming fog. This phenomenon is more common in winter. If not handled properly, it can severely affect driving and even lead to accidents. Besides using the defogger button, you can also use a defogging agent for the windows, which is available online or at car wash locations.

Here's how I activate this feature: After starting the car, immediately locate the button with the windshield icon on the climate control panel and press it to initiate operation. The system will automatically direct airflow to the windshield for defogging. I recommend also turning on the A/C switch as it helps absorb moisture for faster results. For vehicles with automatic climate control, simply press the AUTO button without additional settings needed. Don't worry about fuel consumption if the fan speed seems high. For better dehumidification, remember to switch to external air circulation mode to allow fresh air in. When the windshield gets severely fogged, I usually pull over safely before operating to avoid distracted driving. Cleaning the interior glass surface regularly also helps prevent fog buildup.

As a long-time commuter, here's my go-to method: Upon entering the car, locate the climate control panel and press the button with the windshield fan icon to activate defogging. Ensure the A/C is on for better dehumidification. Adjust the temperature to warm to accelerate fog dissipation. I also prefer switching to external air circulation to prevent interior humidity buildup. If response seems slow, consider upgrading your vehicle - though the principle remains similar. Regularly clean windshield grease as preventive maintenance for safer driving.

The operation is very simple: After starting the vehicle, directly press the front windshield defogging button on the air conditioning panel, which is usually located in the middle or a prominent position. Once activated, the air will blow towards the windshield to clear the fog. Be sure to turn on the A/C to help with dehumidification for better results. You can adjust the temperature higher or lower depending on the season. Safety tip: If the fog is severe, pull over before operating, and avoid fiddling with it while driving. Keeping the windshield clean can prevent issues.

Here's how I handle it: After getting in the car, turn on the air conditioning controls and press the button with the windshield defrost symbol to activate it. Turning on the A/C for dehumidification will work faster, and the fan speed usually adjusts automatically. You can set the temperature a bit higher as warm air works better. Switch to external circulation to prevent fogging from recirculated air inside the car. Regularly clean the inside of the windows with a cleaner to reduce the issue. If the fogging is excessive, pull over to operate safely.
