Why do the glasses on the VAZ 2110 sweat?

Very often, in winter or in rainy weather, one has to deal with the problem of fogging the windows in the car. On the VAZ 2110 and other models, the reasons may be different, but there are several main ones that are worth checking right away.

1. Incorrect position of the recirculation flap. It turns out that if the damper is constantly closed, then fresh air will not flow into the cabin, and this, in turn, leads to the fact that the glass begins to sweat.
2. Clogged or clogged cabin filter for heater. This is also common, since not all owners know about its existence at all.

As for the first point, I think everything is clear with it. And in the second case, the first thing to do is to change the filter of the air entering the cabin. It is located under a plastic lining near the windshield, on the outside of the VAZ 2110. That is, the first step is to remove it, and only then you can get to the cabin filter.

When removing the old filter, do it as carefully as possible so that no debris gets into the heating system (air ducts), otherwise all this can clog the system and the air flow will not be as efficient as it should be. Replace the cabin filter at least a couple of times a year, and then you will not have problems with fogging.
