How to fix foggy car windshield in humid weather

The temperature difference between inside and outside the car, along with high humidity, causes the car windows to fog up. Here are some simple ways to quickly fix this problem.

Lowering the car windows helps balance the temperature

Lowering the window is the simplest and most fuel-efficient way to help balance the temperature inside and outside the car, avoiding condensation. In case it is not raining and not too cold, you can lower the window about 10 cm. If you drive in the rain, you can lower the window enough to leave a small gap of about 3 cm, or choose another solution.

Turn on the fan with outside air intake mode

Turning on the fan and using outside air intake mode also helps to balance the temperature inside and outside the car, avoiding condensation on the glass. This method should be done when the glass is just starting to fog up, or when the steam has not yet accumulated on the windshield or rear window.

Use air conditioning system

Select the windshield air mode on the air conditioning system, adjust the air level and temperature appropriately because if it is too cold, it is easy to cause condensation on the outside of the glass.

Do not use air conditioning at hot temperatures to dry the condensation on the glass because condensation on the windshield is due to the temperature difference inside and outside the car.

Glass drying system

Front and rear window heating systems are commonly equipped on current car models. The front and rear windshield heating system buttons are usually located on the center console, close to the air conditioning system, with a separate symbol and when activated, an indicator light will turn on.

Automatic glass drying system

Normally, in car models with automatic air conditioning system, the windshield defroster will automatically turn on and off after a certain period of time. If the windshield defroster does not turn off automatically, the user can turn off this function after the car windows are no longer steamed to optimize fuel and air conditioning system./.
