AvtoVAZ strives to produce products that will be useful in cold weather. The engine starts working even at a temperature of -30 degrees, and the door locks are also adapted to the cold. The designers tried to include a heated Lada Vesta windshield in the package, as this is a product of very high comfort.
However, not all models are equipped with this feature. The heated windshield of Lada Vesta is designed to ensure that car owners do not experience discomfort when driving in cold weather. Previously, I had to fight ice and snow with my own hands, which took away my strength and patience.
Peculiarity
Owners of the sedan and crossover drew attention to a technological feature - the heated windshield of the Lada Vesta and Iks Rey cannot be turned on remotely, even if the engine starts automatically. For this reason, many, after remotely starting the engine, even when the power unit is warming up, have to wait until the windshield melts.
On models equipped with air conditioning, this problem is unlikely to occur, since the “climate” unit, after turning off the engine, remembers previously activated functions and also activates them the next time it is started. Therefore, in order not to wait until the glass melts, you just need to remember to turn on its heating, and at the same time the mirrors, before turning off the engine.
As for the versions equipped with air conditioning, there is no memory function. However, as practice shows, it is quite possible to independently connect the heated windshield of a Lada Vesta or X Ray to an additional alarm channel.
About heated seats
The heating works quite efficiently. The only drawback is the lack of heating sensitivity. That is, there is no option to select power (low, medium, high), as on some foreign cars. But it does not “fry” all the time, but automatically turns off/on while the indicator is on.

Advice from professionals
- For information on how to properly and effectively repair a windshield, read our article “A crack in the windshield, how to fix a crack with your own hands.”
- Never attempt to replace or install heated glass unless you have sufficient experience and knowledge.
- As an alternative to a heated windshield, there is a portable heated windshield that operates directly from the cigarette lighter, and a special washer fluid reservoir heater.
- A heated windshield allows you to cope well with the problem of icing, without the need to stir the windshield with all kinds of brushes and scrapers. Which often cause many small scratches.
- Despite all the advantages of heating the windshield. Heat often causes cracks in the windshield.
Dismantling
To connect, you first need to log in to the SAUKU, the heating and air conditioning control unit. On Vesta and X Ray the algorithm is different, so it’s worth taking a closer look at everything.
Lada Vesta
In a sedan, the SAUKU unit is traditionally located on the center console. To get there, you need to remove 3 elements:
- Panel coating (plastic);
- Lock;
- Cover of SAUKU.
The plastic cover is attached to the center console using plastic fasteners. To separate them, you need to pry the bottom and pull it towards you.
After this, the panel with the keys is disassembled, which is attached to the latch cover, including around the entire perimeter. They need to be disconnected.
The most difficult thing is to remove the SAUKU cover.
It is best to start working on the left side. First you need to get to the fuse box by removing the plastic cover that covers it. You need to tighten the 3 plastic handles that secure the lid from below, and then remove the lock from above.
In the end, all that's left is to pull the lid off from the bottom, undo the clips that secure it to the top of the order, and remove the lid. When the fuse box cover is removed, you will need to remove 2 mounting screws.
Then we move to the central part, where you also need to unscrew the 2 mounting screws, which are located directly under the panel with the keys.
Then it remains to unscrew 1 mounting screw on the right side, which is located under the glove box lid.
After this, access opens directly to the SAUKU lock, which is attached to the escutcheon with Torx screws. Unscrew them and disconnect the plug.
Lada X Ray
Independent connection of a heated windshield to the Lada X-Ray via an additional signal channel also begins with the removal of the SAUKU unit. Everything here is much simpler than on Vesta. The panel itself with the block is fixed with two hooks in the upper part and two iron guides equipped with springs in the lower part.
You need to carefully lift the panel at the bottom and carefully pull it towards you. This will release the top supports. In the end, all that remains is to disconnect the wires.
Fuse box and relay Lada Vesta
Information about fuses and relays is suitable for Lada Vesta cars in standard, norm and luxury versions.

To access the fuses and relays, turn the three plastic handles that hold the block cover from below. Pull the bottom of the cover, disconnect its upper holders to the instrument panel and remove the unit cover.
To improve the fastening properties of the fuse box cover, a trim holder clamp is used, see the figure below. Before removing the fuse box cover, you must first remove the trim holder retainer. After installing the fuse block cover to the standard mounting points, it is necessary to additionally secure it with the trim holder clamp, installing it in the hole in the fuse block cover.

Description of the relay in the block under the Vesta instrument panel
Types of damage
The windshield is made of triplex, an impact-resistant material that has two layers of glass and a thin film in the middle. This prevents the parts from falling apart upon impact.
Masters divide damage into two types:
- Fries. Only the top layer was damaged. No immediate replacement is required.
- Cracks. In this case, deliver new material as quickly as possible. The film holds the debris, but not as firmly as before, and with a hole, which is not uncommon on our roads, they will separate. This will lead to an accident.
If you can’t change it in the near future, you can resort to some tricks:
- Make perpendicular cuts along the edges of the “web”.
- Drill 5mm holes along the edges of the slot.
- “Brew” the damage.
All measures will have a temporary effect and the spare part will still have to be replaced.
How to turn on the heated windshield
The design of the heating visor on the Lada Vesta is identical to its foreign counterparts. The function is controlled by the ignition button in the car's interior, which is also responsible for the electrically heated mirrors and rear window. In maximum configurations, Lada Vesta is equipped with a “MAX Defrost” button. This function provides for the simultaneous activation of high speeds of the stove fan, which significantly reduces the heating time. The function instantly activates the air conditioning, which is necessary to eliminate the effect of fogging, as this causes poor visibility and causes unnecessary inconvenience to the driver.
Lada Vesta stove: symptoms of breakdowns and treatment
In a Lada Vesta car, the stove heats the interior, but as it turns out, this is not its only function. They use it not only in winter, but also in summer. The territory of the Russian Federation is dominated by a temperate climate
In cold winter, the stove becomes an important function on a Lada Vesta car. This unit is necessary when it rains, when it’s cold, when you need to quickly remove fogging from the windows, or warm up the few moving people in the cabin.
In the advanced configuration of the Lada Vesta, the air conditioner can create a comfortable temperature in hot weather. The Lada Vesta stove does its job well. But like in any car, problems happen: the heater radiator leaks, the fan makes noise, or there is vibration. Replacing the stove is important on a Lada Vesta car not only in winter but also in summer. Read the article and you will be warm and comfortable in your car.
How heating works on Vesta
The windshield is pierced with the finest transparent threads, which directly perform the main function of incandescence located in the layers of glass. They can be viewed in full sun and do not cause discomfort while driving. The mechanism also includes cables, relays, and a fuse located under the front panel of the car. When turned on, the relay closes the contacts of the cap grid, as a result, the current, spreading through the system, heats the windshield. An important part of the design is the electronic control unit, which regulates unnecessary energy costs and, if necessary, turns off the heating.
Causes of heating malfunction on Lada Vesta
With the introduction of the heated glass function, complaints began about the non-functioning of the heated windshield. However, the reason may not be the failure of the thermal option. As noted earlier, heating efficiency is observed down to -10 ° C. If the thermometer drops below, be patient and wait.
Sudden changes in temperature can lead to warping, cracking, which will cause serious problems as replacing glass takes time/money. The optimal waiting time for the visor to warm up in severe frosts is 10-15 minutes.
Also, the reason why the front heating does not work may be a blown fuse, in which case it is necessary to replace the part.
Which Vestas are heated?
The basic configuration is not equipped with this function. You will find Vesta's heated windshield starting with the "Comfort" version. The minimum price of such a car is 592,000 rubles, and it is constantly being adjusted. Compared to the basic configuration, the difference in cost is about 75 thousand rubles.
If you need this function, but don’t have enough money for an expensive package, you can do it differently. You can install the option after purchasing the car. It will be much cheaper, especially if you install it yourself.
The “luxury” configuration will have “Defrost Max” - the button discussed above. It simultaneously connects rear and front heating, as well as heated side mirrors, air conditioning and air supply.
Necessary tool
To ensure that the replacement of the VAZ 2110 windshield goes smoothly, you should get a gluing kit. When purchased through an online store, the TEROSON PU kit will cost about 1,150 rubles, but will quickly recoup the costs. Its composition:
- instructions for use.
- applicator;
- cloth for cleaning surfaces;
- 8596 sealing adhesive;
- cartridge nozzle;
- primer;
- cutting wire;
In addition, you need to have other devices on hand:
- new consumable.
- several office knives;
- solvent for nitro paint;
- a set of flat screwdrivers and spatulas;
With an assistant, changing parts is easier and faster.
Price is not a guarantee of quality! But you shouldn’t take the cheapest materials either - fakes are not uncommon.
Connection
Not all 2180 owners are satisfied with the heating of the windshield, rear windows and rear-view mirrors simultaneously with the heater fan and air conditioning. There is a way out of this situation - installing a separate button. Even on Vesta models that do not have a windshield heating function as standard, it is possible to activate this very convenient function in case of replacing a double-glazed window. If for technical reasons there is a need to replace the heated windshield, you must contact an official Lada dealer. Under warranty, the procedure is free, subject to examination. You need to make sure that replacing your defroster windshield is the only solution to the problem as no part will serve you better than your own. Careful operation and compliance with specialist recommendations will significantly extend the heating time. Avoid high water pressure on the windshield when visiting a car wash. Timely replacement of windshield wiper blades is required, as low-quality wipers will scratch the surface of the glass.
Checking and replacing the heating relay
Typical VAZ heated glass relay
Over time, problems with the heated rear window are often associated with circuit faults, a blown fuse, and a blown defroster relay:
- The purpose of the relay is to turn off the heating when the engine is not running. The most important thing is that heating does not drain the battery
- On vehicles equipped with a relay, this system can be housed in a standard relay box or fuse box
- It is very important here that the coil of this relay is constantly connected to ground
- In VAZ model cars, the rear window heating relay is used to turn on the heating for a certain time for fifteen minutes
- This system works thanks to the built-in timer
- And instead of the standard relay, a new one is simply inserted and the heating is turned on with the standard button
Relay replacement
If the glass heating does not work due to a relay malfunction, the instructions prescribe the following actions:
- This heating function is very convenient and even necessary
- We connect the conclusions of the 4th and 6th
- The heater relay must be located in the fuse box, which is located inside the car
- Then remove the heater switch from the instrument panel and disconnect its connector
- Be sure to check the status of the heater timer
- The indicator lamp (test) of the switch lights up when turned on and goes out after 12 minutes
- Then we check the operation of the heating element
- We turn on the heating by pressing the power button, after twenty minutes of operation the heating automatically turns off
- First, disconnect the battery from the ground
- It lights up only when the ignition key is turned in the lock and continues to work when the engine is running
- You can install the relay in the rear window heating system yourself or at a service station if you are satisfied with their price
- If the switch fails, it must be replaced
- If something goes wrong, you will need to replace the switch
- Next, you should check the condition of the circuit between the ends (terminals) of the 1st and 3rd connectors located on the relay side
- Then the condition of the circuit on the side that goes to the switch connector is checked
- When the ignition key is in the off position, there will be no voltage
Replacing the radiator of the VAZ 21129 Lada Vesta stove
To replace a stove radiator with your own hands:
- It is necessary to turn off the power to the car, free the cooling system from antifreeze;
- Remove the plastic trim of the instrument panel;
- Remove the top panel in the glove compartment, remove the glove compartment;
- The unit is located in the heater block on the driver's side, you need to free access to it - remove the metal pillar of the dashboard frame, remove the air pipe for heating the driver's feet;
- Disconnect the pipes (be prepared for antifreeze leaks);
- Open the cover of the stove device with a Torx screwdriver;
- Remove the heater/cooler from the heater housing;
- Install a new spare part;
- Reassemble the structure in reverse order.
Lada Vesta drives on Russian roads. Passengers should be warm and comfortable. The new AvtoVAZ stove (with a cooling glove compartment for drinks, heating the driver’s feet) copes with its job “excellently”. But any device fails sooner or later. If faults are diagnosed and corrected in time, the device will warm your feet and soul for a long time.
Operating principle, control unit
Lada Vesta in the “Comfort” configuration is equipped with a windshield heating system. Other modifications do not have this advantage; drivers are forced to use the oven heater to defrost the glass.
Sequence of actions when activating the mode:
- Shift to neutral.
- We insert the key and start the engine.
- After at least 1-2 minutes, press the MAX Defrost button on the windshield defroster.”
- Wait until the ice on the glass melts.
- If necessary, also turn on the heater.
- When finished, turn off the mode.
Control unit for ventilation and heating system with air conditioning (manual control)
- After turning on the air conditioner (separate button No. 18), the indicator lights up. Cooled air enters the car, and the humidity drops sharply.
- To cool the incoming air, press button No. 18.
- The minimum air temperature depends on the degree of air outside, the angle of solar radiation, fan speed, active recirculation mode and driving speed.
- The air supply mode is adjusted by pressing buttons numbered 11 – 16, the indicator light lights up.
Be sure to start the vehicle engine before activating the air conditioning system. Do not turn on the cooler when the outside air temperature is below 5 °C from approx.
- Do not direct the air flow towards the body, limbs of the driver or passengers.
- Before starting the air conditioning system (hereinafter - AC), make sure that at least one or more deflectors on the dashboard are in the open position. Otherwise, the air ducts will freeze and the SC will fail.
- It is strictly forbidden to direct a flow of cold air onto the windshield or side windows. This will lead to freezing and dulling.
- While the air conditioner is operating, moisture and condensation will accumulate under the bottom of the car on the asphalt. Don't worry, this is a natural process.
Active air conditioning consumes 5-7% of the power from the power unit and also increases fuel consumption by 3-5%. The indicator values are averaged; the higher the speed, the higher the consumption. When driving in mountainous areas, the SK coils can turn off automatically, as the load on the engine increases several times.
Flaws
Let us dwell on the negative aspects of the heating function:
- expensive replacement in case of breakdown. The slightest impact on the glass, for example, a pebble from under a wheel, leads to the appearance of cracks and huge cracks. Repairs can cost up to 100,000 rubles depending on the make of the car.
- temperature changes can lead to destruction of the glass surface (especially if the ambient temperature is -30 degrees). But it is worth saying that special relays are now used to solve this problem;
- the presence of thin threads forming a mesh interferes with the operation of radar detectors and other gadgets;
- high price for installing such an option (especially on German cars);
Malfunctions of the heating control unit
If after 5-7 minutes of operation the glass does not heat up, check the conditions:
- generator operation, measure the output current values.
- electrical wiring, in the area from the control unit to the generator, distributors;
- fuses (numbers 38, 44);
To carry out a complete diagnosis, seek help from a service station specialist. Only for prevention use a device such as a multimeter.
Conclusion
In the Lada Vesta Comfort, the glass heating can be turned on at the touch of a button. After a few minutes, the surface of the glass will be clear of ice and snow.
Of course, in critical frosts, when the temperature is below -17 - 18 ° C, the system is not so effective; it takes more time to “warm up”. To speed up the process, additionally turn on the heating element of the stove and turn off the air supply to the cabin through the dampers.
What are fuses used in cars?
Fuses are an indispensable part of any car, which is necessary in order to prevent short circuits in the electrical circuit that can lead to a fire. If the current exceeds the maximum permissible value, the fuse opens the electrical network.
Such an inexpensive part can save more expensive ones and save huge amounts of money on repairs. Agree that it is much more convenient to buy a fuse for a LADA Vesta that costs only a couple of tens of rubles. The cost of a fuse depends on the amperage for which it is designed.
The fuse consists of a working element, two contacts and a plastic housing.
If the fuses in the LADA Vesta fail for some reason, they should be replaced as soon as possible. It is recommended to avoid driving altogether until they are replaced. Without this element, you risk losing expensive parts and even more - creating an emergency situation on the road, because many of them affect the control of the car.
Self-installation
Autonomous installation of a heated windshield will require knowledge not only of electrical circuits, but also of installing the panel.
To integrate the option you will need:
- We remove the old windshield.
- Purchase and install a new one with heating threads.
- Connect the heater terminals to the power source.
- Install the relay and rear window heating button.
It is important to understand that not all models offer this feature. Therefore, installation is possible only if the system is provided for by the project and is installed in advanced configurations
To install the rear window, you will need to follow the same steps as for the front window.
Heated injectors and wipers also require intervention in the car's wiring and the insertion of an additional button.
- connect complete blocks, relays and connectors.
- We carry out the wiring according to the diagram from the set of heated brushes;
- install the key into the console;
- remove old cleaning products;
Installation of injector wiring is no different from installation of heated brushes
it is important to select in advance a suitable part with a reliable fastening to the hood cover
How the standard heated windows, mirrors and seats work on Vesta
AvtoVAZ tried to make the Lada Vesta sedan as adaptable to winter conditions as possible. The design of the door locks prevents freezing, and the engine can start even in severe frost (down to -30 degrees). In addition, the manufacturer equipped Vesta with heated windshields, mirrors and seats. Let’s check how well these “warm” Vesta options work in practice.
It’s -20 degrees outside, start the engine and turn on the heater (to blow the windshield and side windows), and also press the button on the panel, which is responsible for:
- heated side mirrors (at the beginning of 2016, AvtoVAZ began installing the “Electric drive and electrically heated exterior mirrors” option on all Vesta trim levels);
- heated rear window;
- heated windshield (optional).
The front seats are equipped with electric heaters, which are activated by a button on the tunnel near the gearshift knob.

Checking the operation of the heated windshield
The efficiency of the windshield heating, like other heating systems in the car, depends on the ambient temperature. Vesta owners have noticed that at -3 degrees, only 3.5 minutes are enough for the ice and snow from the windshield to melt. Then we make one sweep of the wipers and all the ice goes away:
At lower temperatures, for example, when it is -20 degrees outside, the windshield heats up more slowly. Thanks to the heater, after 3-4 minutes the first signs of thawing appeared at the bottom of the glass. The main part of the ice disappears only after 7-10 minutes, you can go.
By the way, if the filaments are clearly visible inside the glass and the heating does not work, contact your dealer with this question; it is possible that this option is simply not activated on your car.
On Lada Vesta SW and Lada Vesta SW Cross, the heated windshield is activated with a separate button. Heating efficiency on video:
Results
In severe frost (at -20 degrees), the defrosting procedure will be something like this:
- 7-8 minutes: heating has melted the ice from the main part of all glasses, you are good to go.
- 4 minutes – the mirror elements are completely dry, the snow melts on the rear window wires;
- 5-6 minutes: the windshield and areas on the side windows near the mirrors move significantly away from the ice;
- 1 minute: the ice on the mirrors begins to melt;
- 2.5 minutes - the ice on the mirrors has almost melted, the bottom of the windshield (stove) begins to melt);
In warmer climates, you can start driving earlier, once the engine speed drops to operating speed. There are no comments on the operation of Vesta’s heaters; one can only criticize the fact that the seat heating is not adjustable.
How to use it correctly
Considering that the heating function is new and has a number of shortcomings, activate the mechanism if the temperature outside is not lower than 10-15°C. At a lower degree, performance is not guaranteed.
As soon as the melting process has begun, do not rush to activate the windshield wipers, as the remaining ice can easily damage the brush and rubber coating. To effectively clean the glass surface from snow, allow more time for heating.
