The windows in the VAZ 2114 car are sweating

That time of year has begun when it’s warm in the car but cold outside, and immediately after sitting in the car the glass starts to sweat) this is especially unpleasant when it’s in a parking lot and the rear window is fogged up and you can’t see how to get out of it) and you have to wait until it starts to sweat)

and somehow I was filling up at a gas station and noticed this product called ANTI-FOGGER) well, it cost about 250 rubles) I bought it, tried it and somehow the windows magically and truly didn’t start sweating) it basically lasts for a long time) I think it’s better than applying water with salt, etc. )

With the onset of cold weather, when there is an excessive amount of moisture in the air and large temperature changes, one of the most common problems that arises among drivers is fogging of the car windows. This phenomenon occurs when the ambient temperature decreases, as a result of which the glass cools. Accordingly, since heat and moisture in the cabin do not evaporate , but cool near the glass, it settles on it in the form of tiny droplets. It is enough to sit in the car for only 2-3 minutes for the windows to become covered with tiny drops.

Of course, in this case, visibility deteriorates sharply, and the glass changes from transparent to dull-opaque. The driver ceases to see the surrounding situation, and moreover, he is also distracted in order to wipe the glass while driving, thereby increasing the risk of getting into emergency situations. If the windshield and two front side windows are still somehow saved by airflow and heating, then the rear ones simply “perish.”

Most car owners with experience in this regard give many different tips, which boil down to one thing - you need to change the cabin filter. But is this really so? What causes car windows to fog up?

Why do glasses sweat?

Condensation on the inner surface of the glass appears when there is even a slight difference in temperature on one and the other side of the surface. Even by one or two degrees Celsius. And the greater this difference, the faster and in greater volume condensation appears . So, it can appear not only in the most common case, when the driver and/or passengers sit in a cold cabin, and as a result of their breathing the mentioned condensation appears on the windows. This phenomenon can also occur in the case, for example, of driving in cold tunnels or under overpasses, that is, where the ambient air temperature is lower.

The physics here is simple. At an air temperature of +20°C and a relative humidity of 60%, the amount of moisture is 9.6 g/m³. However, if the temperature is lowered to +9°C with the same moisture concentration, the relative humidity will increase to 100%. And this is the direct reason for the appearance of condensation on the surface of the glass in the car.

Causes of fogging

There are several main reasons why glass sweats. Moreover, each factor can influence both the general fogging situation and the fact that the windshield or only the side or rear window will sweat more. Let's do this in the form of a table.

What reasons influence window fogging?	Head-on	Driver's license	Lateral	Rear
Cabin filter
Wet seats
Incorrect airflow
Fume
Failure of the stove and/or internal ventilation

Cabin filter clogged or too dense

Due to the fact that it does not cope with its functions, a closed air space without ventilation is formed in the cabin. The temperature rises over time, the air heats up and the windows in the car sweat from the inside due to the physical phenomenon described above.

It is worth noting here that the cabin filter may not only be clogged, but also simply incorrectly selected, in particular, too dense. Its material does not cope with the passage of sufficient air and moisture remains in the cabin. This is the same reason why car windows sweat when you turn on the heater. In this regard, many motorists advise installing a standard filter in the cold season , and a carbon filter in the warm season. The standard one is not as dense and, accordingly, allows air to pass through it better.

Wet seats in the car

The main reason that seats become wet is that some moisture enters the interior and is absorbed by the foam seat. In turn, this phenomenon can be caused by the following factors:

passengers and/or driver in the cabin wearing wet outerwear (after snow, rain);
bad (old, rotten) rubber seals on car windows or doors;
leaving the car with open doors in a damp room for a long time;
spillage of liquid on the seats (a banal spill of water or other liquid, due to which it is absorbed and can remain inside the seat for a long time).

It is worth noting here that the humidity in the cabin can also increase due to the fact that the car is standing in the cold for a long time and then suddenly moves into a warm atmosphere.

Moisture under rugs

Wet floor mats are also the main source of moisture in the car interior in winter and autumn. And in turn they cause significant fogging of windows. There are several reasons why moisture accumulates on or under them:

clogged floor drains;
applied and subsequently melted snow in winter or wet shoes of passengers/driver in the rain;
leaking (even slightly) stove or its lines.

How does fogging occur?

Most car owners with experience in this regard give many different tips, which boil down to one thing - you need to change the cabin filter. But is this really so? What causes car windows to fog up?

What to do if the glass sweats

There are 10 useful recommendations that will help you deal with the situation when your car windows sweat. These include:

Inside the cabin, the glass must always be clean , you cannot touch it with your hands, you must wash it using detergents, and then wipe it dry with a clean material. At temperatures below 25 degrees below zero and when traveling with passengers, it is useful to treat the glass to prevent freezing.
Use a product to prevent the windows in your car from sweating, the so-called anti-foggers . It can be either popular or store-bought. Treatment with them will allow, in damp and winter seasons, to significantly reduce or completely remove (depending on humidity and temperature) fog on the inner surface of the glass.
It is necessary to monitor the condition of the cabin filter and stove . Their correct functioning will allow you to quickly get rid of fogging when the car engine is already running.
Follow the warm-up sequence . Blowing warm air should be directed first to the windshield, then to the side windows, and only lastly to the rear window.
Set up the correct air intake . It must come from outside, since the outside air is not as humid as inside the cabin.
Monitor the condition of the interior ventilation . If necessary, check and clean drainage channels.
Turn on not only the stove, but also the air conditioner (if you have one). You need to use your car air conditioner in both hot and cold weather. With its help, you can quickly get rid of fogging by turning it on to warm mode (provided the air conditioning system is working properly). It dries the air well.
Dry the interior . The windows rarely sweat when cars are stored in a warm garage. When drying, it is advisable to open all doors in a warm and dry room.
The climate control system must be turned off.
Check the air recirculation valve.

It will also help to get rid of the problem of sweating windows in the car by periodically checking leaky places in the car, such as antenna sockets, mirror adjusters and glass seals, to prevent precipitation from getting into the interior.

Moving forward in solving the problem, car enthusiasts use many different cunning methods and techniques for eliminating glass fogging. It all starts by “opening” the window so that fresh air can enter the cabin, then the problem solves itself - someone uses various sprays, “anti-foggers”, a wide selection of which is offered on the market. But all these methods are for the most extreme cases or as a temporary solution to the problem.

The procedures listed above will allow you to partially or completely get rid of the situation when the windows in your car sweat. This depends on the set of measures taken, as well as the specific situation (humidity level in the cabin, serviceability of ventilation, stove and other listed hardware).

Folk remedies: what can you rub on the surface of windows to prevent fogging?

We are talking about long-proven methods for removing condensation from glazing. An experienced driver always carries some of the funds with him. However, most of them are sold in regular stores.

If the windshield fogs up from the inside, use:

Regular table salt. Rub the problem surfaces with its solution, and as a preventative measure, place the dry product in bags on the center console;
Lemon. Take half a citrus fruit and wipe the glass with it. Fogging will stop, and you will get a pleasant aroma in the cabin;
Soap (no matter household or toilet). Apply any shapes, drawings, lines to the surface. Use a damp cloth to wipe the glass over the entire area;
Shaving cream (foam). It is used in exactly the same way as soap, but the process, due to the semi-liquid state of the product, goes faster;
A solution of alcohol in glycerin in a ratio of 1:20. Treat surfaces with a cotton swab, a clean rag or a spray bottle (the one used to spray plants is suitable).

Before using any of the above methods, the inside of the glass must be wiped with a cloth, sponge or newspaper to remove as much moisture and dirt as possible.

Silica gel in rag bags - and 5-6 more of them and spread around the cabin. You can instead use cat litter or salt as a last resort. There will be no moisture in the cabin air - no condensation on the windows. Well, shake off the snow from your feet. Water from the rugs as an enema to the street

hello, please tell me how to get rid of this problem: when the damper of the stove is completely closed, warm air still blows from the nozzles, what is the problem, tell me where to go and what to do

Roman, thanks for the video. Good luck

What kind of glass treatment solution is needed to prevent car windows from sweating?

The owner of the car treats the windows in the cabin with a special anti-fog aerosol.
You need a so-called “anti-fog”.

Among the autochemical cosmetics with a similar focus on action there are:

sprays
liquids
special napkins

Buy any product with this characteristic and wipe all glass with it once a week.

The windows of the VAZ 2110 are sweating

Prerequisites

The question of why the VAZ 2110 windows sweat is one that many owners of a similar car model periodically ask themselves. And for good reason. The problem is urgent, and it should be solved promptly, since it complicates the process of driving a car, and in general, attempts to wipe the windshield turn off attention from the road traffic, and it won’t be long before you become involved in a road accident. And no one needs this.

Logically, if the glass fogs up, there is only one reason - high humidity in the cabin. But when asked why windows fog up, many begin to generate their own versions. Skeptics believe that you shouldn’t expect much from a brand like VAZ, but those who know how to think logically suggest that perhaps the problems lie in the air filter, while others blame the air supply system for everything.

Someone is right, but someone just needs to be open-minded about the manufacturer of the VAZ 2110.

If the glass fogs up for a long time, and the problem is not found, then other problems will appear, such as corrosion and a specific odor, since excess humidity is an ideal environment for fungus, mold and harmful bacteria. As you can see, efficiency is the main thing here!

Causes of high humidity

Superficial reasons

Before starting diagnostics, take into account factors that are not related to the operation of VAZ 2110 systems. For example, the windshield fogs up due to external climatic conditions. Wet weather, and the accompanying wet shoes and rugs that absorb large amounts of moisture, will provoke condensation on the coldest areas inside the VAZ 2110 interior, which are the glass. The problem can be eliminated by ventilating the interior and drying the rugs.

Moisture on the carpet of VAZ 2110

In winter, such a factor can be a car heater. Moisture enters the interior through the stove opening, the function of which is to intake air. It is located at the top of the hood. The snow that has accumulated there begins to melt as the engine heats up, and as a result, there is a high level of humidity in the cabin. In winter, to eliminate this problem, remove snow from the hood as often as possible.

Causes in equipment

If the above options do not solve the problem, then the main reasons for moisture condensation on the windows of the VAZ 2110, as for other models, remain the following:

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 windows sweat. Also occurs when the valve is faulty and stopped working when it was in the closed position. This can be easily checked by turning on the stove to maximum, and outside, for example, exhaling cigarette smoke into the air intake hole (under the windshield). If smoke is observed in the cabin, then the problem is not with the valve, and vice versa: the absence of smoke is an indication that the problem is with the valve. Will have to replace;

Cabin filter dirty. This is the most common problem, although many car enthusiasts simply do not know about its presence. As a rule, it is discovered when it turns out that it is the cause of increased humidity in the cabin. It is located under a plastic trim, at the base of the windshield, on the outside of the VAZ 2110. That is, first you need to remove the wipers, remove the trim, and then you can get to the cabin filter (it is located on the right). You need to remove the filter as carefully as possible, as debris can get into the air duct system. In the future, this may negatively affect the ability to effectively pass air. After installing a new filter, many people put a mesh on top; it reduces the entry of leaves and various debris into the filter.

Correct diagnosis of your car, taking into account the information obtained from this article, will 100% solve such a problem as high interior humidity.

Reason 4: Drain holes are clogged

Normally, excess moisture is removed from the interior air through ventilation. Under the hood of the car there are special drainage holes through which condensate is discharged outside. When these holes become clogged, excess fluid does not escape. It accumulates and at some point may leak through the filters. The result is high humidity in the cabin and condensation on the windows. Most often, a problem with the drainage holes occurs after dawn, when leaves and dirt get into the engine compartment.

Solution: Check to see if the drain holes under the hood are clogged. If necessary, clean them.

They forgot to say that only the original stove heats. All others do not heat.

don’t spare money on the stove, it’s better to have a brass aluminum stove radiator that’s crap, you’ll only suffer

You can also pour a special cooling system sealant into the expansion tank, if the holes are small, this should help. The sealant clogs this hole and hardens. The trick is that it comes into effect upon contact with air. And when it is in the system, it is liquid and does not spoil the cooling system in any way. It also helps with problems with an external large radiator, but this is for small cracks and holes. At least some alternative to buying a new radiator

By the way, the glass in my Lada actually sweated. I didn’t know what to do, and one fine day there was a puddle of antifreeze under my feet. I replaced the radiator and the glass stopped sweating. I just now realized why =

Roman, you forgot to mention ventilation. On classic sedans, valves are installed in the rear pillars; if they stop working, it is quite possible that the windows will sweat, at least the rear ones. I have a four, there are no valves and I often see foggy windows on the rear doors and in the trunk. In a cold car, the windows sweat due to the fact that during breathing a person releases moisture, which settles on the windows. To get rid of fogging when it’s cold, just open the window a little or turn on the heater; it’s still cold in the car.
