Heated windshield Lada Vesta

How does the morning begin in winter? When others clean the windshield with plastic cards, the windshield heating on Vesta turns on. Snow covering roads and vehicles, coupled with low temperatures, causes inconvenience for motorists - they tried to solve this problem with the Lada Vesta. Russia is famous for its harsh winters. AvtoVAZ tried to adapt the new models to the winter season. The Lada Vesta engine starts even in 30 degree frost, and the design of the locks prevents freezing. Additional options on the luxury model, such as a heated windshield, rearview mirrors and seats, are a bonus for drivers. In cold weather, you don’t need to manually remove snow and ice deposits with a scraper; just turn on the heated windshield. On the Lada Vesta, heating will quickly and easily remove snow and ice. It is also recommended to use this function in a blizzard with snow, to remove excess load from the mechanism driving the wipers. Read the article to the end and find out how to enable it, how it works and what problems are encountered with this function!

How to use it correctly

Owners of Lada Vesta have already noticed the dependence of the heating operation on weather conditions and temperature conditions. The heating function is most effective when the air temperature is not higher than -10 degrees. When the snow flooring has slightly melted and moved, you can remove it using the wipers; hastily turning it on can lead to deformation of the brush drive mechanisms. At lower temperatures, it takes longer to warm up the glass. In this case, you should not expect an instant result from the function.

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:

How to turn on the heated windshield

The design of the windshield heating on the Lada Vesta is identical to its foreign counterparts. The function is controlled by one power button in the car's interior, which is also responsible for the electric heating of the mirrors and rear window. The maximum configuration of the Lada Vesta is equipped with a “Defrost MAX” button. This function involves simultaneously turning on the high speed of the stove fan, which significantly reduces the warm-up time. The function immediately activates the air conditioner, which is necessary to eliminate the effect of fogging, since this is the reason for the deterioration of visibility and causes unnecessary inconvenience to the driver.

Heated windshield Lada Vesta

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.

How to turn on the heated windshield

The glass heating function Heating Lada Vesta does not provide a separate connection option. The heated windshield and side mirrors are turned on using one single button on the dashboard. Turning off the heating is synchronized with the same button. The windshield heating turns on quickly and operates depending on weather conditions.

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:

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.

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.

How heating works on Vesta

The windshield is pierced with the finest transparent filaments, which directly carry out the main function of incandescence; they are located in layers of glass. They can be seen in bright sunlight and do not cause any inconvenience when driving. The mechanism also includes wires, relays, and a fuse located under the front panel of the car. When turned on, the relay closes the contacts of the grid of filaments, 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 excess 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 that the heated windshield did not work. However, the reason may not be a breakdown of the thermal option. As previously noted, the heating efficiency is observed down to -10'C. If the thermometer drops below, you should be patient and wait.

Sudden temperature changes can lead to deformation and cracks, which will cause significant problems, since replacing glass requires time/money. The optimal waiting time for the windshield to heat up in severe frosts is 10-15 minutes.

Also, the reason why the windshield heating does not work may be a blown fuse, in which case the part needs to be replaced.

Heated windshield does not work

“The heated windshield of the Lada Vesta does not work” is a fairly common request on the Internet. This situation makes you think: “Isn’t everything so unreliable?”, but somehow I can’t believe it. Let's figure it out together

Lada Vesta in any configuration has heated rear window and side mirrors. As for the windshield heating, it is not installed on all trim levels, i.e. the owner of the basic “Classic” version will have to pay extra for it.

On the dashboard, the climate control unit has two buttons for heated windows and mirrors: one button turns on the heated rear window, the other turns on the heated windshield directly.

The following complaints are encountered among owners on this topic:

• Heated glass does not work below -15
• The glass heating does not work evenly
• Heated glass does not work

Before we look at each problem separately, let's see what AvtoVAZ itself tells us about heated windshields.

“The main task of windshield heating is to freeze frozen ice to the windshield, followed by its removal using a scraper, as well as removing fogging from the windshield.”

It is also worth noting that AvtoVAZ recommends using a heated windshield in tandem with a directed air flow from the heater to the windshield, which cannot be done in foreign cars (we immediately remember cracked windshields), i.e. a priori, heating the windshield serves as a kind of assistant to the stove, rather than as a separate tool for removing snowdrifts and ice from the windshield.

Now let's go over the problems separately

Heated glass does not work below -15

In fact, the heating still works, it just takes much longer at lower temperatures.

The glass heating does not work evenly

It’s also not a completely correct remark, because... if the heater blowing is directed at the windshield, then the wiper area thaws first, and only then the rest of the windshield slowly thaws.

But it is possible that the windshield has a defective windshield with torn heating threads. In this case, you need to contact the office. To the dealer.

Heated glass does not work

A sign is the windshield heating button that does not turn on and the absence of signs of windshield thawing in the area of ​​the threads, even at relatively warm temperatures from -1 to -5. In this case, you should refer to the fuse box. I will note in advance that there are several fuses: one responsible for the heating itself and one for the relay. The fuses for the windshield heating are located in the engine compartment: open the hood, find the fuse box, carefully pry up the lugs on opposite sides (they are very fragile), remove the cover and gain access. It is recommended to check all the necessary fuses and, if necessary, knock on the switches. See fuse diagram. Check fuses f75 and f80 . If the fuses are intact, but the heating still does not work, contact your authorized dealer about this problem. Home page

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:

• Using the heated glass mode on the Lada Vesta.

• heated side mirrors (at the beginning of 2020, 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.

Windshield Installation

You will need : a sharp knife, a repair kit for gluing the windshield (read the instructions), a glue gun, a heated room (recommended air temperature 23°C, humidity 50%).

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.

Heated windshield Lada Vesta

After the onset of winter, there were many complaints about the Lada Vesta windshield heating not working

, however, most often the problem does not lie in the fact that the heating is broken. The operation of this function is quite easy to observe up to 10 degrees below zero, it literally melts the ice on the glass before our eyes, but when the temperature drops below, the heating efficiency drops. This is due to a possible temperature difference; if the heating inside the cold glass is turned on at full power, the glass will probably burst, which will cause much more problems than ordinary ice interfering with the driver’s visibility. In cases when the temperature outside drops below 15 degrees, the glass heating will not cope in a few minutes; it is quite possible that its operation will take about 10-15 minutes.

In some cases, the glass heating actually stops working; if this happens, the first thing you should do is check the fuse. Sometimes the heated windshield does not stop working entirely, but only in separate stripes. This situation is very easy to diagnose - when the heating melts all the snow on the windshield, you will notice characteristic stripes of snow that form in the places of the faulty stripes. All of the above cases, except for the case of a blown fuse, can be solved by completely replacing the windshield.

Defrost MAX mode

On luxury Vestas with air conditioning, the “Defrost MAX” mode appears. It allows you to most effectively clean all windows and exterior rear-view mirrors from fogging, freezing or icing. To enable this mode, you need to press the corresponding button (No. 24) on the climate control unit.

When the mode is activated, the air conditioning (if conditions permit), electric heating of the windshield and rear windows, as well as side mirrors will be forcibly turned on. The entire air flow is directed to the blower nozzles of the windshield and front side windows, and the maximum air speed and temperature are also set.

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.
