Allowed or disorderly?
Many drivers know the problem - in the autumn, the windows fog up faster because it is cooler and wetter. The reason is because cool air can store less moisture than warm air. That is why the moisture condenses on the cold panes, especially at night.
Before you start the blind flight in the morning, first set the blower from circulating air to fresh air supply and direct the high-level air distribution to the windscreen. Also, keep the heater warm and the windows closed. If you have an air conditioner, switch it on as well because the air conditioning dehumidifies the interior. If all else fails, you should check your ventilation and, if necessary, properly dry your vehicle.
Check whether the ventilation slows in the engine compartment underneath the windshield are free of leaves and dirt. There are also ventilation openings in the boot or on the rear window. If these openings are blocked, it can lead to misted windows. In addition, water can accumulate in the so-called air calming box or in the heating, which sooner or later goes into the interior and leads to misted windows.
Is everything tight?
The seals on doors, sunroof or windows often let moisture into the interior, especially with older cars. With special care products such as talcum powder or silicone oils you can counteract this. In addition to old gaskets, clogged water drainage holes in the doors often cause moisture in the car. If it smells musty and the carpets are constantly wet, the car should be dehumidified. At the hardware store you can find special dehumidifiers for this.
