How to turn on the heated windshield on a Lada Vesta - tips

AvtoVAZ strives to produce products that will be suitable for use in cold weather. The engine starts working even at a temperature of -30 degrees, door locks are also adapted to cold weather. The designers took care to include a heated windshield in the Lada Vesta, as it is a product of the highest comfort.

However, not all models are equipped with this function. The heated windshield of the Lada Vesta is designed to ensure that car owners do not experience discomfort when driving in cold weather. Previously, I had to deal with ice and snow myself, which took strength and patience.

How does a heated windshield work?

Heated glass The option of heating the windows of the Lada Vesta is an indispensable and primary function for the operation of the car on harsh and cold days.

• There is no longer any need to manually scrape ice from the front and back of the machine. Heating removes ice from the front, rear and mirrors of the car in a short time. In case of strong wind and snow, it is also worth turning on this useful option on the Lada Vesta.
• The heating efficiency of all glass and mirror elements depends on the ambient temperature. Owners of Lada Vesta note that ice and snow thaw in three minutes at -3 degrees. If the ice does not drain away on its own, it is wise to use your windshield wipers. In colder weather, it takes longer for the heater to heat not only the interior, but also the outside area of ​​the car.

Stove malfunctions

Lada Vesta is a warm car. The car should be warm and comfortable. If this is not the case, it means that one of the heater elements has broken down. What problems you may encounter:

• The temperature of the supplied air does not correspond to the declared one (the system does not have enough antifreeze, the radiator of the Lada Vesta stove is clogged, an air lock has formed in the pipes, etc.);
• Vibration of the stove or extraneous noise (most likely this is an electrically driven ventilation device);
• Weak or excessive air flow (dampers are not working properly);
• The heater does not work at all (there may be problems with the electronic control system, serious damage to the heater body, etc.).

Heated windshield does not work

The operation of the function can be easily monitored at temperatures down to – 10 degrees. It handles ice and snow with ease. However, at a lower degree, heating productivity rapidly decreases. It takes a little longer to deal with the problem. You should not turn it off immediately without noticing the result.

Possible causes of the problem and their solution:

1. If the heated windshield of the Lada Vesta really stops turning on, you must first check the condition of the fuse, and if it breaks, replace it with a new one.
2. It happens that the heating function works partially and does not thaw small strips of snow on the windshield. The only thing that will help here is to completely replace it with a new one.

Most car owners, in the event of a breakdown and a warranty card in hand, prefer to contact dealers with a question about a replacement if the heating turns off on the Lada Vesta. At the first complaint, sellers refer to the fact that the problem will be solved by itself, because turning on the function works well in mild frost. If the owner agrees to replace the windshield, it is worth remembering that an incorrect repair will cause more trouble than a problem when the defrost does not turn on, and you need to wait a little longer.

Connection

Not all 2180 owners are satisfied with the operation of heating the windshield, rear windows and rear-view mirrors simultaneously with the heater fan and air conditioning. There is one way out of this situation - installing a separate button. Even on Vesta models that do not have a heated windshield function as standard, it is possible to connect this very convenient function when replacing the glass unit. If you need to replace your heated windshield for technical reasons, you should contact an official Lada dealer. Under the guarantee, the procedure is carried out free of charge, after an examination. It is necessary to make sure that replacing the windshield with heating is the only solution to the problem, since not a single part will last better than the original one. Careful operation and compliance with the recommendations of specialists will significantly extend the service life of the heating device. High water pressure on the windshield should be avoided when visiting car washes. Timely replacement of wiper blades is necessary, because poor-quality wipers scratch the glass surface.

How does heated glass work?

1. Buttons distribute air flow.
2. Starting the air conditioner.
3. Air recirculation mode (intake from the cabin or outside).
4. Temperature setting.

Vesta's heated windshield is similar in design to other cars. Its button is indicated in the picture in the center and surrounded by a red circle.

This system consists of several parts:

• switch in the cabin;
• in expensive versions of Vesta, a “Defrost Max” button is installed, which, together with heating, activates the air conditioner and maximum air pressure;
• heating filaments inside the windshield, they can only be seen in the sun;
• electrical wiring, relay, fuse link are located under the front panel.

Defrost Max button on Lada Vesta “Lux” configuration

The “Defrost Max” button activates a relay that supplies current to the filament. As a result, the windshield heats up and thaws away ice and snow.

The system is configured in such a way that after a while the automation turns off the power so as not to waste extra energy.

Dismantling

To connect, first of all, you need to gain access to the SAUKU - the heater and air conditioning control unit. On Vesta and X Ray, the algorithm is different, so it’s worth looking into everything in more detail.

Lada Vesta

In a sedan, the SAUKU unit is traditionally located on the center console. To get to it, you will need to remove 3 elements:

1. Panel overlay (plastic);
2. Key block;
3. SAUKU overlay.

The plastic trim is fixed to the center console using plastic fasteners. To snap them off, you need to pry it at the bottom and pull it towards you.

Next, the panel with the keys is dismantled, which is attached to the clamps, also around the entire perimeter. They need to be snapped off.

The most difficult thing to remove is the SAUKU trim.

It is better 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 turn the 3 plastic handles that secure the lid at the bottom, and then remove the lock from above.

In the end, all that remains is to pull the cover from below, disconnect the clamps that secure it to the device from above, and remove the cover. Once the fuse box cover is removed, you will need to remove 2 mounting screws.

Next, we move on to the central part, where it is also necessary to unscrew the 2 mounting screws, which are located directly under the panel with the keys.

Then all that remains is 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 block, which is attached to the cover plate with Torx screws. They need to be unscrewed and the plug disconnected.

Lada X Ray

Independent connection of a heated windshield on a Lada X-Ray through an additional alarm channel also begins with the removal of the SAUKU unit. Everything here is noticeably simpler than on Vesta. The panel itself with the block is fixed with 2 hooks at the top and 2 iron guides equipped with springs at the bottom.

You need to carefully pry the panel at the bottom and carefully pull it towards you. This will cause the top fasteners to disengage.

In the end, all that remains is to disconnect the plug from the wires.

How to turn on the heated glass on Vesta

There is no separate heating button on regular Vesta trim levels. The heated front window starts working from one button, which is responsible for heating the rear window and side mirrors.

The operation of the system depends on the ambient temperature. If the temperature outside is down to -10 degrees, then heating will quickly melt the icing on the glass. But if it gets colder, the efficiency decreases noticeably. The greater the temperature difference between the cabin and the outside air, the less power the windshield heating is turned on. This is done to prevent the glass from breaking.

To speed up the process of defrosting the windshield, additionally turn on the heater at the highest blowing speed. To prevent fogging, turn on the air conditioner additionally.

Attention! Do not rush to turn on the wipers - they may fail if they do not have time to thaw. Wait until the snow starts rolling down the glass, then you can turn them on.

Connection

Not all 2180 owners are satisfied with the operation of heating the windshield, rear windows and rear-view mirrors simultaneously with the heater fan and air conditioning. There is one way out of this situation - installing a separate button. Even on Vesta models that do not have a heated windshield function as standard, it is possible to connect this very convenient function when replacing the glass unit.

When the disassembly of the interior components is completed, it is necessary to program the additional alarm channel for a pulse lasting 1 second when controlled from the key fob. Next, the additional signaling channel needs to be connected to the plug of the SAUKU unit (black). For Lada Vesta this is a green wire, the second one from the edge, which is marked in the picture.

As for X-Ray, the location should be identical, but before connecting it is strongly recommended to inspect everything with a multimeter - when the heating is turned on, the wire should briefly produce ground.

After this modification, the connection of the heated windshield on the Lada Vesta and X-Ray through the additional alarm channel will occur from the key fob. And after a few minutes the heating will turn off on its own.

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.

Probably everyone knows the morning winter symphonies of various sounds in the courtyards. First, the wipers break the snow crust and rake tons of snow with iron shovels, and then the sounds are born, thanks to other wipers - the ones that are stuck to the windshields of most cars parked in the yard. This is especially true when the temperature fluctuates near zero and the thawed water on car windows turns into ice. Until recently, this was the only method to prepare a car windshield for driving in the cold season.

Fortunately, engineers from automobile companies noticed this problem not long ago and provided an excellent way out of it - a heated windshield. This technology did not pass by the new Lada Vesta cars. In this article, we will look in detail at the question of how to turn on the heated windshield on Vesta, and also find out in which trim levels this option can be found.

1 — air flow distribution buttons, 2 — air conditioning button, 3 — recirculation mode button, 4 — air temperature adjustment handle.

Air recirculation mode

Activation is carried out by button No. 19, the indicator light lights up. The air supply from outside is blocked, the climate control system takes the air flow inside the cabin.

The “Recirculation” mode is used to prevent smoke and exhaust gases from entering the cabin, as well as to accelerate the heating of the cabin during the first start after a long period of inactivity.

Note to the driver!

Do not overuse recirculation, as the lack of fresh air in the cabin causes drowsiness in the driver and passengers. Often this factor becomes the cause of accidents. To deactivate the mode, use the mechanical button (number No. 19). To start heating the rear and side windows, press button No. 15 once.

How does the heated windshield work on Vesta?

The windshield heating device on the Lada Vesta is no different from similar installations on other cars. This node can be divided into several elements:

• A switch located inside the car.
• In expensive Vesta configurations there is a “Defrost MAX” button, which, in combination with heating, turns on the air conditioning and maximum heater fan speed.

• Transparent filaments located inside the windshield (between the layers). They directly carry out heating. If you carefully examine the glass in sunny weather or take a photo, you can see them.
• Wires, fuse and relay located under the dashboard.

When you press the button, the relay closes the “plus” to the contact of the grid of incandescent filaments, after which the windshield is heated by current. After some time, the electronic control unit automatically turns off the heating to avoid unnecessary energy consumption.

Do-it-yourself modification

You will need: install an additional non-locking button in the car panel (or buy a block with five buttons), a relay with two groups of switching contacts, 1N4007 diodes and a transistor.

Description of the circuit: When the button is pressed, the low level at pin S1-14 activates the standard heating of the entire CBKE and at the same time the relay is activated due to the pickup by the transistor for a time determined by the capacitance of the capacitor. After 3-4 seconds, a low level appears at pin S1-34 and fixes the relay in the on state for the time specified in the CBKE (6 minutes). The relay turns off the heated mirrors and rear window, leaving only the windshield.

As a result, when you press the additional button, the indicator of the standard button lights up and only the heated windshield turns on. After 6 minutes it turns off on its own.

How to use heating correctly

Unfortunately, the heated windshield of a Lada Vesta does not provide adaptability to the ambient temperature. Therefore, defrosting time varies depending on weather conditions. As the practice of using Lada Vesta cars shows, at temperatures just below zero, the snow begins to “slide” within 3 minutes. At -20 degrees, you can wipe off the thawed snow with your wipers in 5-10 minutes. At lower temperatures, the heating time will correspondingly increase.

Thanks for subscribing!

In order to significantly reduce the heating time, simultaneously with heating, turn on the stove fan to maximum power. To prevent the windows from fogging up, it is also recommended to turn on the air conditioning. Do not rush to use the wipers under any circumstances - if you turn them on too early, the wiper drive mechanisms may be damaged. Wait for the snow to move and then turn on the wipers.

The photo shows the glass after 8 minutes of heating at an outside temperature of -13 degrees. The rear one has become transparent, but on the windshield there is only a narrow embrasure from the heater fan blowing. If you wave the wipers, they will not cause any damage to the ice on the glass. The photo shows the glass after 8 minutes of heating at an outside temperature of -13 degrees.

However, electronic diagnostics revealed some errors, and they were erased from memory. So far the frosts have receded, so I can’t say anything about changes in the heating operation yet. Taking this opportunity, I would like to ask the owners of Russian cars and foreign cars with a warm windshield: how efficiently does it heat up in yours?

Lada Vesta from ZR park: going for service

Which Vesta configurations include heated car glass?

Unfortunately, in the basic configuration of the Lada Vesta, you are unlikely to find such an option as a heated windshield. The minimum configuration that includes heating is Comfort. The cost of Vesta with a set of Comfort options is at least 592,000 rubles (at the end of March 2022). If you compare it with the base, the difference in price is a little more than 75,000 rubles.

If you fundamentally need this option, but there is no way to overpay almost a hundred thousand rubles, then you can install a heated windshield on your car in the future - it will cost much less, especially if you do this work yourself.

In Luxe trim levels you will receive the “Defrost MAX” button, which was already mentioned above. This button comprehensively launches all possible systems to speed up the heating of all windows and side mirrors of the car.

Self-assembly

The car owner can implement the windshield heating function on his own without spending a lot of money, which is the main advantage of this option.
You can choose the simplest type of system - install the elements on the wipers themselves or on the glass in this area, and equip them with a regular network connection. More complex heating involves filaments throughout the entire area of ​​the glass and its perimeter. This can be supplemented with a power regulator to reduce the risk of cracks. An alternative option is the installation of finished glass with a built-in heating system, which is rarely performed outside of special workshops. For the first two types of heating, there is no need to dismantle the factory glass, which reduces risks.

The main element of the entire system is the heaters. This can be a solid mesh with metal dots on an adhesive base or the metal threads themselves. The second option is more convenient because it leaves a better view for the driver and allows it to be mounted strictly in a given area of ​​the windshield. You will also need connection wires and switches. Experts advise assembling stationary versions, for example, with output to a regular button, and not for connection to the cigarette lighter socket. This is safer from a car electrical point of view. Additionally you can use:

• relay;
• power regulator;
• controllers;
• temperature sensor.

The owner will need a low-power soldering iron to install the elements, insulating tape and a button. The first stage is glass preparation. It must be carefully inspected for cracks and deep chips. Then clean from dust and grease using alcohol-containing substances. This will ensure better adhesion of the elements to the surface. Glue metal threads or ready-made strips to the glass, avoiding creases, bends and deformations. The second stage is to connect the electrical wiring to the car’s standard power supply through the control unit. It is better to place the unit under the hood, and not inside the panel in the cabin. In this case, it will be more convenient to carry out repairs if the heating fails.

It is better to place heating elements in standard positions: near the washer nozzles, under the wipers and around the perimeter. Here they will not interfere with the view, but will prevent icing of the main functional units. Additionally, you can install a complete power shutdown button in the cabin. To do this, you need to bring the contact to the dashboard and mount a regular two-position switch. Thus, it will be possible to turn off the element completely in the summer.

Heated windshield systems are a useful option that is necessary in harsh climates with cold and snowy winters. But in summer and autumn, it is also necessary, especially if the windows sweat a lot, and the stove and air conditioner cannot cope with the air flow. It is quite possible to save money and not overpay the salon for additional equipment: anyone who knows how to connect wires and glue film to glass can assemble the glass heating themselves and attach it correctly.

At any time of the year, the driver needs a properly working car. And sometimes some details are considered not so important, but according to the law of meanness, they will be needed in difficult times. One of the troubles that can happen to a driver on the road is damage to the rear window heating system. Both in winter during cold weather and in summer during rainy weather, this function of the car must be performed in full. Otherwise, moisture will enter the cabin, and visibility will be reduced to the limit, as a result, the driver will be forced to repair the rear window heater of the car.

Rear window heating repair

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:

1. Fries. Only the top layer was damaged. No immediate replacement is required.
2. 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:

1. Make perpendicular cuts along the edges of the “web”.
2. Drill 5mm holes along the edges of the slot.
3. “Brew” the damage.

All measures will have a temporary effect and the spare part will still have to be replaced.

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.

Results

In severe frost (at -20 degrees), the thawing order will be approximately as follows:

• 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 thaw;
• 4 minutes - the mirror elements are completely dry, the snow on the threads of the rear window will melt;
• 5-6 minutes - the windshield and areas on the side windows near the mirrors noticeably move away from the ice;
• 7-8 minutes - the heating has melted the ice from the main part of all the windows, you can drive.

In warmer weather, you can start driving earlier, as soon as the engine speed drops to operating speed. There are no comments on the operation of Vesta’s heating; one can only find fault with the fact that the seat heating is not adjustable.

Often on forums, in VK groups, etc. I see complaints from owners that glass heating does not work well. Many people say that the windshield heating does not work at all. Interesting, I thought. Everything is fine with me.

Posted the video on YouTube. And so it began... All the commentators, owners and those who were not even close to Vesta, as well as various “experts” in heating, began to assure me that everything was wrong, it was not true, the engine was warm and that sort of thing. There were many opinions that it was just warm, and at -10°C and below, the windshield heating does not work “a hundred pounds”.

Some believed. Some doubted that it was -20. Although the snow creaked a lot and I filmed it (who doesn’t know - the lower the temperature, the better you can hear the creaking of the snow). And the regular BC showed -19. But then, as the engine warmed up, it began to lie, as usual. You should have placed your street thermometer next to the car. But I didn’t want to tear the windows off the plastic. Well, okay, the weather forecast for the Belgorod region will help them. Some said that everything was nonsense, although then I still didn’t understand lying to me. Some have become convinced that heating is not needed for nothing. To be fair, it is worth noting that there are people who agreed - yes, windshield heating is a good thing. Here I am attaching both videos. They are long - because of distrust, I didn’t cut anything out. If you are interested in this question, take a look. Tell us in the comments if this option is useful and how it works for you.

Fuse box in the passenger compartment of VAZ-2170, -2171, -2172

The fuse box in Priora is located at the bottom of the dashboard, on the left side of the steering wheel. To get to it, you need to open the cover, which is held on by three latches. Rotate each locking knob 90 degrees and pull the lid down and it will snap open.

Fuses in the interior mounting block

F1 (25 A) - radiator cooling fan. If your fan does not work, check its motor by applying 12 V directly to it from the battery. If the engine is working properly, then most likely the problem is in the wiring or connectors. Check the serviceability of relay K1.

The fan in the Priora usually turns on at a temperature of 105-110 degrees. Do not allow the engine to overheat, watch the arrow of the temperature sensor.

If the fan runs constantly and does not turn off, check the coolant temperature sensor located on the thermostat. If you remove the connector from the working sensor, the fan should turn on. Check the wiring to this temperature sensor, as well as the contacts of relay K1, move this relay, clean the contacts. If this is the case, replace it with a new relay.

F3 (10 A) - high beam, right headlight. F4 (10 A) - high beam, left headlight. If the headlights do not shine on high beam, check the K7 relay and the headlight bulbs. The steering column switch, wiring or connectors may also be faulty.

F5 (10 A) - sound signal.

If the signal does not work when you press the steering wheel button, check relay K8. The signal itself is located under the radiator grille; you can get to it by removing the plastic casing from above. Check it by connecting the voltage to 12 V. If it doesn’t work, try turning the adjusting screw, or replace it with a new one.

F6 (7.5 A) - low beam, left headlight. F7 (7.5 A) - low beam, right headlight. When replacing lamps, be careful; there are separate lamps for the low and high beams, so they can be easily confused. It is better not to install lamps in high-power headlights; the reflectors may melt and the desired effect will not be achieved. Most low beam headlight problems that cannot be corrected by conventional means can be related to the light control module (LCM). The low beam relay is only available in cars equipped with a light sensor, it is located in the place of relay K1; on most cars this relay is not in the mounting block; the low beam circuit goes through the MUS block. It happens that the tracks in the block burn out; if there are problems, it is better to replace it with a new one. If the windshield wipers turn on spontaneously when the low beam is not working correctly, the problem is most likely in the windshield wiper control unit, located in the center of the dashboard, the topmost block, next to the radio, is best reached from the glove compartment, or by hand through the removed console covers at the feet.

F8 (10 A) - alarm signal. If the alarm does not work, also check relay K9.

screensaver

Vesta was not deprived of options. Having given money for them, naturally, you want them all to work and fulfill their functions. There were a couple of “saboteurs” on our car.

All Vestas have automatic door locking when starting to move, but ours refused to lock the doors when the speed reached 7 km/h from the very beginning. The instructions are silent about the fact that this function can be disabled, but experience with foreign cars suggests that there are usually “on” and “off” modes. And so it turned out: after holding the key on the front panel for several seconds, the auto-lock turned on, although only for five to ten cycles, after which it had to be activated again.

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.

Quality issue

Technically, heating the car area is a very simple option.
Double-layer glass and metal threads or mesh do the job. You can heat the entire surface or work only with the most problematic areas: the wiper line, center or corners of the area. However, experts do not recommend saving on the system. You can find versions on the market at a low price, but they will have all these disadvantages and will most likely impair visibility, reducing the level of driving safety. Higher-quality types of heating are more expensive, but last longer, do not require seasonal repairs and do not suffer even due to long-term downtime. Problems with the quality of heating arise for those who buy systems separately from the car and not from the manufacturer. Even installation through an authorized dealer or an authorized workshop may not guarantee high quality. Sometimes, if purchased separately, not as an option for a new car, the cheapest assemblies can be installed here, which rarely last longer than the warranty period and often lead to cracking of the glass. The best option would be to install it yourself. However, it is necessary to understand that electrical safety should come first.

You can either install ready-made heating systems yourself or assemble them from scratch using simple elements.
