Driving in winter in Pakistan can be challenging due to thick fog and condensation on windshields and windows.
Moreover, many drivers make common defogging mistakes, including improper use of climate control buttons and poor interior maintenance. These mistakes not only fail to clear the fog but can make the situation worse.

It can help drivers ensure safe driving in various tricky situations. Let’s delve inside!
Incorrect Usage of the Recirculation Mode
Recirculation mode is responsible for cooling and heating the cabin air. During defogging, the car owners leave the recirculation mode “on”, thinking that it will warm up the air inside and clear the fog.
In this mode, the trapped, humid air is continuously recirculated into the car, where it condenses onto the cold glass of the windshield. It can cause fog and moisture buildup, reducing visibility.
For this, the drivers need to turn off the recirculation mode as suggested by the user on Quora and switch to fresh car air intake. The fresh air would replace the moist air inside, making it easier for the defogger to work efficiently.
Not Using the Defogger Properly
Many drivers in Pakistan are unaware of how to use the defogger properly. The defoggers work by directing warm air to the windshield and side windows to remove moisture.
Moreover, a Reddit user has shared helpful information about the dehumidification procedure.
If there is condensation and moisture buildup on the front windshield (often caused by breathing saturated air inside the cabin or wet clothes), the driver should turn on the front defrost and AC. The latter is set to blow air on the windshield.
The AC will act as a dehumidifier, removing moisture before the air is blown into the cabin through the vents. It also helps prevent fog from accumulating on the cold windshield.
The A/C removes moisture from the air while the warm air from the heater is directed to the windshield to clear condensation. Solely turning on the heater to full blast without AC might not work effectively.

Using Rear Defogger Button
Now, the drivers might be thinking about what to do if fog builds up on the rear windshield.
It’s usually a button marked with a symbol resembling a rear window with wavy lines ( indicating heat). When activated, the rear defroster will send warm air to the electrical heating elements embedded in the rear window. This helps to defog or defrost the back windshield.
Overheating the Car Interior
Another common mistake Pakistanis make is overheating the car’s interior, leading to rapid temperature changes. Eventually, this can cause condensation on the windows, especially if the outside temperature is cold.
Dirty Windshield and Windows
Car owners should avoid driving with dirty windshields and windows in winter. It is because dirt, grime, or even oil smudges can trap moisture and worsen the fog.
It is therefore advised to wipe inside and outside of the car with anti-fog sprays and glass cleaner. For this, the buyers are advised to buy a streak-free window and glass cleaner, a Bullsone anti-fog trigger type, and a Flamingo interior glass anti-fog spray from PakWheels Autostore.
These products can help them to maintain shine and enhance visibility in foggy weather conditions.

Not Replacing Cabin Air Filters Regularly
Drivers often neglect to replace cabin air filters on time. Moreover, the most common symptoms for replacing cabin air filters include;
- A dirty or clogged cabin air filter restricts airflow, fails to manage moisture inside the vehicle, and cannot defog the windows.
- It also creates an unpleasant odor due to the trapped dirt or mold.
- If the driver has more dust or debris coming into the car from the AC vents than usual, and it’s accumulating faster, the driver may consider changing them.
- Drivers and passengers may be prone to sneezing, allergies, or other respiratory issues due to poor cabin air filters.
Important Note: Drivers may consider changing the air filters every 1 to 3 years or after 15,000-30,000 miles.
Ignoring Interior Maintenance
Car owners also need to keep the inside of their cars clean and well-maintained. The moisture can build up inside the vehicle from wet clothes, shoes, floormats, and carpets. It will increase the car’s humidity when the heater is on.
Furthermore, check under the car and beneath the carpet for any holes, as road spray (including water, dirt, or debris, especially when it’s wet) can seep through, leading to wet carpets and contributing to condensation.
Important Note: Use carpet and mat cleaner to remove dirt and dust from the car interior.
Pro Tips for Preventing Fog During Winter Driving
Park in Dry, Sheltered Areas
Park away from moisture sources, such as lakes or wet roads, to minimize condensation inside the car.
Use Low-Beam Headlights for Better Visibility
In foggy conditions, use low beams and maintain a safe distance from other vehicles. Adjust your defogger and heater settings to clear windows quickly.
Opt for Winter-Ready Wiper Blades
Use winter wiper blades to prevent streaks and improve visibility, especially in snowy or icy conditions.
Cover Windshield Overnight
Use a windshield cover to keep moisture off the glass overnight, making it easier to defog the next morning.

By following these defogging techniques and maintenance tips, car owners will be better prepared to handle foggy winter conditions and maintain clear visibility.
Proper car care and proper use of climate control systems can significantly reduce fog and improve road safety.
