Windows in the car sweat when the stove is on - reasons, how to fix the problem
Content
As a prevention of fogging, you can use a special glass cleaner in the form of a spray or wipe. It will not allow condensation to settle on the glass. Window processing lasts an average of 2 weeks. In order for the product to work effectively, the glass inside the car must first be washed, dried and degreased.
In the cold season, motorists often encounter a situation where, when the “stove” is turned on in the car, the windows fog up from the inside. As a result, you have to manually wipe the glass. To get rid of such a problem, you need to find and eliminate its cause.
Causes of misting car windows when you turn on the "stove" in winter
Window fogging from the inside occurs when condensation settles on the glass due to high humidity. Usually turned on "stove" lowers it, drying the air in the cabin. However, for some reason the humidity remains high when the heater is running.
Activated recirculation mode
In the recirculation mode, fresh air is not taken from the street. The option is needed in order to:
- unpleasant odors and dust from the outside did not penetrate into the car;
- interior warmed up faster.
In this mode, the air masses inside the machine move in a circle. The recommended operating time is no more than 20 minutes. People sitting inside the car are constantly breathing, adding moisture. As a result, the air cannot become drier. Therefore, the windows begin to sweat, despite the included "stove".
Old cabin filter
To prevent dirt from the environment from getting inside the car, a cabin filter is installed. He is able to hold:
- the smell of washer fluid, which is used in winter;
- emissions from other vehicles;
- pollen;
- small particles of debris and dirt.
Manufacturers do not set a deadline for changing the cabin filter in the car. The rate of contamination depends on:
- Ecological situation. In regions with high air pollution, the filter becomes unusable faster.
- The frequency and duration of periods when the "stove" or air conditioner is working.
A clogged filter is unable to fully take air from the street. A situation is created, as with a long-term inclusion of recirculation. Therefore, it is recommended that the filter be changed regularly at each service interval.
Cabin valve malfunction
The ventilation valve is a part through which air is removed from the car to the street. It is usually located at the back of the car. Part malfunctions cause air to linger in the cabin. As a result, due to the breathing of people inside the car, humidity rises, and even when the “stove” is turned on, the windows in the car fog up from the inside.
The main reason for such a breakdown is severe filter contamination. To help in this case, only the replacement of the part will help.
Leaking coolant
If condensation forms on the window when the ventilation and heating systems are working properly, the cause of sweating may be a coolant leak. A specific sign in this case will be the appearance of an oily coating on the windshield. It occurs when antifreeze vapors penetrate the interior of the cabin and settle on the window.
Antifreeze leak
Also, even a small amount of coolant outside the radiator leads to an increase in air humidity. As a result, the glass starts to fog up.
What is the danger of sweating
Why is condensation on windows dangerous?
- Visibility becomes poor. The driver does not see the road and other road users. As a result, the risk of an accident increases.
- Health hazard. If the cause of fogging is an antifreeze leak, people inside the cabin are at risk of inhaling its fumes and being poisoned.
How to prevent your windows from fogging up in winter
In order not to fog up the windows in the car from the inside when the “stove” is turned on, you need:
- Monitor the operation of the ventilation system, regularly change the valve and filter.
- Do not allow wet carpets and seats in the cabin. If moisture does get on them, thorough drying is required.
- Leave the side window slightly ajar while driving. So the humidity inside the cabin will not increase.
- Monitor the coolant level to prevent leakage.

How to set up the "stove" so that the windows in the car do not sweat
By properly warming up the passenger compartment, you can reduce the humidity inside the car and prevent fogging of the windows. For this you need:
- Make sure the recirculation function is disabled. With it, the air will heat up faster, but the humidity will continue to rise.
- Turn on the "stove" and air conditioner at the same time (if any). Set the heating temperature in the region of 20-22 degrees.
- Adjust the maximum windshield airflow.
How to set up a car heater
Before you turn on the "stove", you need to make sure that its shutters are open. So fresh air from the street will flow faster, helping to reduce the humidity inside the car.
Useful Tips
A few additional recommendations to help eliminate the appearance of condensate:
- Sit in a heated cabin, in which the air has already been dried by the heating system. When people are in a cold car, they release a lot of moisture with their breath.
- Do not leave wet things in the car. They will make the air in the cabin more humid.
- Take care of the seats and rugs, timely hand them in for cleaning.
- Periodically dry the interior in a natural way, leaving the doors and trunk open.
- Monitor the condition of the seals on the windows and doors so that the seats do not get wet when it rains.
You can also leave fabric bags with coffee or cat litter in the cabin. They will absorb excess moisture.
