5 ways to keep your car windows from sweating when it rains

In theory, in any serviceable car, glass - both windshield and side windows - should never sweat. However, almost every motorist sooner or later faces the fact that in wet weather, moisture on the inside of the windows blurs the view. Why this happens and how to deal with this phenomenon, the AvtoVzglyad portal understood.

One of the most common scenarios for fogging windows in the rain is commonplace. You get into the car in damp clothes, the moisture from it begins to evaporate intensively and settle on the cold windows. In theory, the air conditioner should easily and simply cope with this problem. He, as you know, has the ability to "dry" the air, removing excess moisture from it.

But it happens that the air conditioning system does not cope with this task. For example, when three passengers are loaded into the car at the same time as the driver, all as one in jackets and shoes that are wet from the rain. In this case, there is a folk remedy in the arsenal of the motorist.

True, it requires preventive application - processing of dry and clean glass. It is enough to rub it with shaving foam or toothpaste. Well, or apply the "fruits of progress" - purchase and process windows with a representative of an extensive class of auto chemical products from the "anti-fog" category.

If the windows are already cloudy from moisture, they can be wiped. But not some kind of cloth, but brutally crumpled newspaper. A paper towel will not work. The newspaper is preferable, since the particles of printing ink that remain after such a wipe on the glass will play the role of an impromptu “anti-fog”.

But it happens that even with dry clothes on the driver and passengers in wet and cold weather, the car interior sweats from the inside. In this case, you will have to look for the cause in technology.

First of all, you should pay attention to the condition of the cabin filter. In the case of “it’s been a hundred years since it’s time to change it”, clogged with dust and dirt, it greatly impedes air circulation inside the vehicle. Which, ultimately, prevents the air conditioner from fighting excess moisture.

If the problem is solved just by replacing the air filter, great. Worse, if it lies in a completely different part of the climate system. It happens that the condensate drain pipe from the condensate evaporator is clogged. Because of it, the humidity in the car during the operation of the climate system is kept at an elevated level. And when general dampness is added to this circumstance, fogging cannot be avoided. If you do not clean the drain!

One more reason can increase fogging - also a blockage, but already the ventilation openings of the passenger compartment, which ensure the exit of air, including wet air, beyond its limits. They are usually located at the rear of the habitable part of the car body and may require cleaning of foreign objects.

But the most unpleasant reason for increased humidity in the car and the fogging of windows caused by it in rainy weather is the leakage of doors and hatches. The most common cause here is damage or wear of rubber seals. When it rains, water seeps through a similar gap and increases the humidity inside the vehicle. Such a problem is not always easy to detect, and its “treatment” may require significant amounts of money.
