Windshield cleaner and washer for VAZ 2110, 2111, 2112

Vote
Well, my hands finally got around to telling you how I defeated the weak writing injectors of the VAZ 2110. At first, when I bought the car, I decided to change the injectors, because the standard ones sprayed very weakly. I bought the same ones I installed on 9k. From viburnum or something like fans. I installed it, tried it, drove it and realized that there was not enough pressure. It blows away with the wind... That's why I abandoned this idea... So we need to do something with the standard ones... But they don't rain at all, even though the fan ones do too... Friends said that on the 12 they generally splashed well o_O. Hmm...I think it means there is not enough pressure. I decided to try connecting the motor directly to one of the injectors and lo and behold! She sprayed divinely: DDDD In short, I realized that I needed two motors... I bought it at the store: a reservoir for 2 motors, a second motor, hoses and new injectors. I installed it, ran the hoses, connected the injectors, turned them a little to the sides, otherwise they both splash into the center)) I connected them according to this “scheme”. I brought the hoses to the frill, then made it through an adapter so that the frill could be removed altogether. And he ran it along the frill to the injectors.

I decided to connect the motors via a relay, why? so as not to load the wiring and so that the voltage on the motors is higher and therefore works faster))

The only thing that happened with this system in six months was the tank 2110 o_O I didn’t understand how it happened, but the plastic there was crap...

I bought a tank from a Priora for 2 engines... changed the rubber bands and installed it) Externally, the tank from a Priora is smaller... but in volume it seems to be a little larger o_O

Mechanical reasons for device failure

Conventionally, the reasons why the windshield washer fails can be divided into mechanical and electrical. But most often they are quite simple, sometimes you can even recognize them by sound, or carry out a simple check.

Let's look at the mechanical reasons first:

• It is likely that the mesh of the cup, which is equipped with the washer reservoir of the VAZ 2110, is clogged with dirt or other deposits, which is why the pump cannot pump the liquid. Here, most likely, you will have to remove the tank, and then see whether the glass with the mesh needs a replacement, or a simple rinsing;
• Instead of a special anti-freeze fluid, in the summer they poured ordinary water, and before the onset of cold weather, even after pouring a normal windshield washer, they forgot to remove the water from the hoses. She froze, and accordingly, washing the windshield became impossible. The solution is to warm up the car, leave it in a warm garage with the hood closed and wait until the water melts, then the pump can drive it out;
• In the above situation or under other heavy loads, the windshield washer motor shaft may turn. At the same time, a hum is heard from the motor, but the pump does not supply anything to the windows. If this happens, then only replacing the mechanism will help;
• The hose has just slipped off, and the liquid does not flow through the nozzles, but somewhere past them;
• The hose going to the injectors is pinched;
• The injectors (fittings) are clogged with deposits or dirt. To check this, simply remove the hose from the nozzle and see if liquid flows. Replacing the injectors will help.

Do-it-yourself troubleshooting

The main reasons for the lack of washer fluid can be eliminated with your own hands.

Cleaning the injectors

Their replacement and cleaning occurs in the same way and it begins with the removal of these parts, the process is as follows:

• open the hood;
• make sure that they have plastic plugs; if they are present, they must be carefully removed;
• take a flat-head screwdriver and open their spring fasteners to remove the injectors.

Installation of new parts occurs in the reverse order.

To wash the injectors and free them from dirt, you should prepare a special cleaning solution of non-chlorinated water and vinegar, taken in equal proportions. The mixture is mixed well and then poured into the tank. After which you need to press the washer lever, even if the water does not reach the glass, it’s okay. So that the components of the solution have time to break down all the contaminants, you need to leave it in the cleaning system for 2 hours, and then press the lever again. After the dirty solution flows out of the nozzles, rinse the hoses with distilled water.

Replacing the motor

It is quite difficult to repair the motor yourself, so most often it is simply replaced.

Installation of a new device is carried out as follows:

• remove all liquid remaining in the tank from the tank;
• disconnect the contact between the battery and the pump;
• if necessary, you can dismantle the tank, but if manipulations can be carried out with a fixed device, then you don’t have to do this;
• remove the electric pump from the tank and unscrew all the hoses going to it, but just remember their location so that after repair they can all be returned to the correct places;
• connect a new pump to the system;
• screw all the tubes;
• connect the battery to the motor;
• pour liquid into the reservoir.

Check the operation of the motor by pressing the washer lever; if you hear a whirring sound from the pump, then everything went well.

Removing the barrel

To remove the windshield washer barrel, you will need:

1. First of all, disconnect the negative terminal from the battery.
2. Disconnect the block from the sensor that measures the liquid level.
3. Disconnect the connectors from the electric pump motor. When reassembling the VAZ 2110 windshield washer, you should remember: the positive terminal has a pink wire, the negative terminal has a black wire.
4. To empty the barrel, you need to open the lid and take out a cup with a mesh.
5. Unscrew the bolt from the fastening nut, not forgetting about the washer installed under the bolt head.
6. Then you need to lift the tank and remove it from the studs.
7. If there is windshield washer fluid left in the barrel, then to remove it, you need to cover the hole and disconnect the hose from the fitting. The drained auto fluid can be safely used in the future, and therefore it is worth using clean dishes for its temporary storage.

Checking the motor

If there is liquid in the windshield washer, but it does not come from the nozzles, you need to check whether the pump electric motor is working. If it is in good condition, check the fuse, as well as the wiring. To do this, after de-energizing the battery and disconnecting the pads from the pump motor (as described above), you need to connect the pump motor terminals directly to the battery terminals, observing the polarity. If the pump still does not work, it needs to be replaced, which is usually done together with the motor.

To make the replacement, you also need to first remove the windshield washer reservoir, and carefully pry off the pump with a screwdriver, and then remove it. It is easy to install a new pump, but before doing so it is highly advisable to replace its rubber seal.

Removing and cleaning VAZ 2110-2112 injectors

Cleaning the injectors of a VAZ 2110-2112 is a job that should be done only if necessary, because the ramp in which the injectors are located and the injectors themselves are practically the very heart of the engine.

That is why they need to be cleaned only if there are problems with the engine - increased fuel consumption, tripping, a significant decrease in power. Only when there is reason to believe that the injectors are clogged can they be cleaned.

Fuel additives are supplied to the market to clean the injector, which must be added to gasoline, but they do not always cope with their job and do it efficiently. And in some cases they can harm the engine, because all the dirt from the injector gets into it, or react with the components of the engine oil.

Removing the VAZ 2110-2112 ramp

Important! All work on removing the VAZ 2110-2112 ramp must be done cold. First of all, disconnect the wires from the fuel pump, thereby de-energizing it

Then we start the engine and wait until it stalls.

We start it again and so on - we repeat the procedure until it stops starting. Thus, we remove pressure from the fuel supply system. After this, you can begin to remove the ramp.

The first step is to de-energize it by turning off the power - the general wiring is located on the interior side. Then we unscrew the fuel hoses and all the electrics that are connected to the fuel rail of the VAZ 2110-2112 - idle speed regulator, pressure regulator, throttle position sensor.

Next, unscrew the two hex bolts that hold the fuel rail in place. Essentially, we can now remove the fuel rail. It can be removed in the upward direction, but it will hardly be possible to do without improvised means. The fuel rail sits very tightly and must be removed strictly parallel to the ground, since any distortion will only complicate the task.

Cleaning injectors VAZ 2110-2112.

All work on cleaning VAZ 2110-2112 injectors must be done on a clean surface - for this it is advisable to spread a clean piece of cloth on the ground or work table. In addition, you will need to assemble a simple circuit from a 12 V light bulb, an injector, wires and a switch. We connect the light bulb, nozzle and switch in series, after which you can start cleaning the nozzle.

It is best to attach a 20-30 cm long hose to the injector inlet using a regular plastic clamp and turn it on, supplying carburetor cleaning fluid (Liqui Moly, RunWay, Hi-Gear or others) and observe the change in the jet spray.

The jet can either expand or narrow (this depends on the level of contamination), which will signal that the hole in the nozzle is expanding and washing away dirt. When the jet stops changing the spray angle, the nozzle is clean.

Unfortunately, the quality of fuel in our country leaves much to be desired. Therefore, cleaning VAZ injectors may well become a periodic procedure that needs to be repeated every 40-50 thousand km. So it’s better to learn how to do it yourself - you will not only save your money, but you will be one hundred percent confident in the quality of your work.

Replacing and removing injectors on a VAZ-2112 16 valves on your own

The injector in a car is almost the most important element in the fuel system. Indeed, in their absence, the operation of the engine will be impossible as a result.

The video below describes in great detail how to remove injectors on a 16-valve VAZ-2112 engine:

Replacing injectors

The VAZ 2110 washer has jet windshield washer nozzles. The big disadvantage of these nozzles is the excessive consumption of anti-freeze or any other liquid, as well as the small area for spraying the glass. You can, of course, adjust them a little, or you can even replace them with fan or double windshield washer injectors. Thanks to such sprayers, liquid consumption will be reduced (by about 1.5-2 times).

What is the difference between standard jet nozzles and fan nozzles? First of all, a jet nozzle tends to shoot out one or two jets of liquid, which are controlled using special tools. A fan injector is a more modern solution, because it can be used to cover a larger area of ​​the windshield. It differs from a jet sprayer in the special design of the nozzle, as well as in the high pressure in the washer system.

However, fan nozzles also have disadvantages:

1. The fan injector quickly becomes covered with an ice crust at subzero temperatures. The problem can be solved, you just need to purchase a heating system.
2. If a large amount of liquid gets on the glass, there is a chance of reduced visibility for a few seconds before the wipers turn on.

However, the disadvantages of fan nozzles mentioned above are not as significant as those of jet nozzles.

Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

However, others do not like the very high washer fluid consumption . There is a desire to increase the glass irrigation area .

To reduce fluid consumption when washing glass, you need to change the nozzles (nozzles):

1. For fan nozzles
2. For dual washer nozzles

Thus, after replacing the nozzles, the consumption of windshield washer fluid will decrease by approximately 2 times. In addition, you can install injectors from a foreign car on the VAZ 2110 (if you happen to have them at hand)

To increase the area of ​​glass washing (watering), you can:

1. Install an additional nozzle
2. Move the glass washer nozzles to the frill
3. Replace jet nozzles with fan nozzles
4. Move the injectors from the frill to the hood

By analogy, an additional nozzle is installed on the fifth door of the VAZ 2111-12.

You can move the nozzles for watering the windshield to the top of the frill. Also in the example, the jet nozzles were replaced with double nozzles of the VAZ 2110.

An example of the operation of standard jet and fan nozzles.

To install injectors on the hood of a VAZ 2110, you will need to drill it and treat it with anticorrosive.
The original injectors were replaced with new ones from Shniva. The glass wash now has a larger area than before. This is how they wash the injectors of a Niva-Chevrolet from the hood of a VAZ 2110 :

Replacement

If the old motor has failed, there is no point in trying to repair it somehow. To buy a new part, you will have to spend very little money. And the replacement procedure on most cars is extremely simple.

I will describe the main stages of work associated with replacing this element of the windshield cleaning system of any car.

Turning off the vehicle's power. A safety measure without which further work makes no sense. Be sure to remove the negative terminal from the car

It's simple but important. Otherwise, you not only risk burning the wiring, but also getting an unpleasant electric shock yourself. Search for a motor

It all starts with identifying where your windshield wiper motor is located. It depends on your car. On some cars, just lift the hood and you will immediately see the washer reservoir. The motor itself is located on the reservoir (partially inside) of the windshield wiper, into which the liquid is poured. Do you see the tank? If yes, then you are in luck. If not, then you will have to look for it by removing elements of the engine compartment. On some car models, the tank is hidden so that the fender protection has to be removed.

• Disconnect the connectors with wires from the motor. Then remove the tank itself.
• The hose and fitting are separated from each other. Don't forget to drain the liquid. Filling a new one will not be difficult. Yes, and for prevention it won’t hurt to do it.
• Using a screwdriver, push the intake seal out of the bushing. This will allow you to completely remove the windshield washer motor.
• Don't forget to install a new bushing when reassembling. This often leads to the washer pump itself breaking down. So the old bushing goes to the landfill.
• Reassemble the assembly in reverse order. Here many craftsmen relax, because they consider the work done. In fact, reassembly causes more problems than disassembly. Advice from someone who made similar mistakes. That is, from me. Do not try to remember the location of parts unless you are confident in your memory capabilities. We got distracted by something, forgot, got confused. This happens to everyone, and there is nothing wrong with it. To ensure proper reassembly sequence, you can record, mark, or label the parts in the order in which they are removed. This will make it easier to put everything back together the way it was before.

The instructions are for informational purposes only, as the procedure may differ depending on the car model. Consult your machine's owner's manual for assistance. This is the best visual aid for self-repair.

There is nothing complicated in this work. Even the car owner who prefers to solve most problems with the help of a car service can easily cope with it. Repairs cost several hundred rubles and take a maximum of a few hours.

This is true, you get used to everything good quickly, the same with the washer, once there was no glass washer or headlight washer, and everyone was happy with everything and it seemed that the car had everything that was needed. Today I propose to talk about the windshield washer and its malfunctions. You will learn why the windshield washer does not work, the reasons for its malfunction and where to look for them.

Windshield washer malfunctions can be divided into two categories - electrical and mechanical. Mechanical ones are more common, but they are usually not very difficult, so they are easier to fix than electrical ones.

So, one fine day you sit behind the wheel, decide to wash the glass, press the button and. nothing happens, liquid does not flow, the glass does not wash. What's the matter? This is the first question that comes to mind after a series of obscene expressions :-))).

Today, a car is unthinkable without a windshield washer; we are too accustomed to the fact that, at our first request, washer fluid splashes from the nozzles, and after it, the wipers wash away road dust and the pitiful remains of insects hitting the windshield. But what to do if suddenly the VAZ 2110 washer motor refuses to perform its functions? If the pump does not work, then you have to forget about the cleanliness of the glass, or wash it the old fashioned way, by hand with water and a rag.

Pump repair or replacement?

The feasibility of repair is determined by the cost of a new pump. A large number of pumps are non-separable, so for repairs you will have to cut them and then glue the plastic case together. To repair it yourself, it is enough to completely disassemble the motor, clean its insides from dirt, corrosion and growths.

Of course, you won’t find spare parts for the washer pump, so the sealing lip will remain old. If it was this that caused the jamming, then within a year the windshield washer will most likely not work again.

Replacement

Having selected a pump that is suitable for its characteristics, you can begin replacing it on your VAZ 2114.

The check showed that the reason for the washer not working was precisely the pump. Therefore, the most optimal solution in such a situation is to completely replace this same pump.

You will spend no more than 30 minutes on the job. Well, if you are completely new to this matter, then you will have to devote about an hour of your time to this issue. In this situation, there is no need to contact a service station. All work can be easily done with your own hands.

1. Remove the negative terminal from your battery.
2. Unscrew the fastening nuts on the washer reservoir, which will allow you to easily remove it.
3. Disconnect the terminals and pull them up, then remove the pump and electric motor from their seat.
4. Examine the condition of the rubber band for signs of wear or tear. But even if it is intact, for the purpose of prevention it is better to immediately replace it with a new one.
5. Put the new pump in place.
6. Return the washer fluid reservoir and connect the terminals.
7. Check the amount of liquid poured into the tank. If necessary, add or completely replace it if it has been there for more than the first season.
8. Connect the negative terminal of the battery.
9. Check the performance of your washer with a new pump.

Refinement of injectors

If the new motor starts its work, the liquid flows through the tubes to the injectors without any problems, then you did everything absolutely right. But sometimes sprayers do not allow you to fully enjoy the work of a repaired washer. They do not spray anti-freeze effectively enough and therefore require intervention.

There are several options to deal with this situation:

1. Install new, unworn standard injectors. Don't expect any major changes, but the washer will definitely work better at first.
2. Use fan or double jets, devices from foreign cars. The main thing here is to choose everything exactly for the connectors. Such jets spray water better and provide better washing of the front end.
3. Install an additional nozzle. The work is not the easiest, but it allows you to get certain advantages from it.
4. Replace factory pipes with more modern and high-quality ones. This way you can avoid liquid freezing in winter. It is noteworthy that in this situation the tubes used in aquariums demonstrate their effectiveness perfectly.

The washer and pump condition must be monitored regularly. You don’t want this device on your VAZ 2110 to let you down at the most inopportune moment?!

Washer nozzles

Loading …

Adjusting the nozzles

If you managed to flush the injectors on your VAZ 2112 car yourself, then you can confidently handle the task of adjusting them. To do this, you need to understand a little about the design features of this device. On a VAZ 2112 car, two types of washer nozzles are used - jet and fan. In turn, jet nozzles can be: single-jet, two-jet and four-jet. This terminology is defined by the method of spraying washer fluid onto the windshield. In the jet nozzles, at the outlet of the washer fluid, a hinged bell is installed. This is a small ball with a through hole. Fan nozzles are equipped with a narrow slot-shaped bell. Now let’s start adjusting the injectors with our own hands:

• The direction of the jet in the jet nozzles is adjusted by turning the hinged bell.
• We insert a thin wire into the hole of the ball and turn the bell in the desired direction.
• Adjustment of fan nozzles according to their design is carried out only in a vertical position; the bell rises or falls to the desired direction. But this is not important; turning them left or right is also possible.

And, in general, no instruction can prohibit you from implementing any technical solution that helps improve the performance of vehicle components.

A few words about the procedure for working with wiring

At the end of today’s article, we’ll look at exactly how you should proceed if you want to change the wiring. As an example, let's take standard models of the VAZ brand - 2110, 2109 and the like. So, to competently work with car data electronics you will need:

1. First, prepare for repair procedures. The implementation of this goal lies through:
2. Purchasing the required wiring and devices;
3. Search for the necessary connection diagrams;
4. Selection of auxiliary tools: harnesses, fasteners, gloves for work, etc.
5. After this, acting according to the diagrams of the currently installed electronics, we completely remove it. Naturally, before this you need to turn off the engine, disconnect the battery and put on gloves;
6. Then the actual replacement of the VAZ wiring begins. Here you also need to act taking into account the connection diagrams. First of all, we connect the injector wiring according to the principle “from the oldest element to the youngest”. Next, we connect the main wiring outputs (ECU contacts) with the current source, and at the end we connect other electronics.

Removing the nozzle

In order to carry out high-quality maintenance, restore the functionality of the nozzle or replace it, first of all, it is necessary to disconnect the wind pad or, as it is popularly called, “jabot”. Or rather, its upper part. To do this, you will need a 10-mm head, a flathead and a Phillips screwdriver.

How to remove the upper part of the windshield

• Using a 10mm socket, unscrew the two nuts located along the edges of the cladding.
• Next, unscrew the four self-tapping screws that secure the cladding. The screws are located under the plugs.
• Then you need to disconnect the sound insulation, which is attached to the wind window trim with six self-tapping screws.
• Carefully remove the top part of the windshield.

Main problems

All existing faults with the front washer can be divided into two main types, which have their own sub-problems, so to speak. We invite you to familiarize yourself with them in the table.

Fault type	Failure options
Mechanical problems	The washer fluid reservoir is empty
The hose fell off the pump
The injectors are clogged
Electrical faults	Fuse burned out
The clamps have oxidized
The switch is broken

But each of these faults deserves a more detailed consideration.

Mechanical breakdowns

It is with mechanical washer malfunctions that owners of the VAZ 2110 most often encounter. This is compared with the regularity of electrical problems.

1. The washer fluid tank is empty. Inexperienced drivers often start blaming a faulty pump, although in practice they simply forget to check the antifreeze level in the tank. Hence the unjustified costs for the services of service stations. Don’t forget to check the fluid level, and in winter, be sure to drain the regular washer fluid and fill it with anti-freeze in its place. Ordinary water at subzero temperatures will turn into ice, and therefore will not be able to take part in cleaning the windshield. If you still forget to drain and the water freezes, warm up the car for a while so that the ice melts, then drain and fill with a suitable liquid.
2. The hose fell off. Anti-freeze is supplied from the tank to the windshield using a pump and special hoses. If these same hoses begin to jump out of their places, the liquid will not be able to flow to the nozzles. As a result, the washer does not function. Try to secure them better. And if they are worn out, simply replace the old hoses with new ones. If the mounting is normal, water may still not flow to the nozzles. In this case, check whether the hoses are pinched.
3. The injectors are clogged. The anti-freeze agent, supplied by a pump and passing through hoses, then exits onto the windshield using nozzles. These are the same small devices from which streams of water come. If they are dirty, disconnect the hoses from the injectors and check their condition. Often the problem lies in the jets. They are easy to clean, but in some situations they may need to be replaced.

Pump and reservoir

Electrical breakdowns

Although mechanical failures are more common, electrical problems should not be forgotten.

1. The fuse has blown. If, when you turn on the device for cleaning the windshield, the pump does not show signs of functioning, there is a fairly high probability that the cause is a failed fuse. Check its condition. If the device really burns out, you can simply replace it with a new one.
2. The switch does not work. If the pump stops working, but the fuse is intact, then the problem may be a faulty steering column switch. To check this, do a little system testing. But for this you will need an assistant. Turn on the ignition and ask a friend to turn on the washer. In this case, go to the pump yourself and check for voltage in it. If there is voltage but no functionality, you will have to change the motor, that is, the pump. If there is no voltage, then the culprit is a switch, relay or wiring. Check everything. Replace what is necessary.
3. The clamps have oxidized. Be sure to check the condition of the pump terminals. It’s not uncommon for wiring to oxidize due to moisture and literally fall apart over time. If this happens to your washer, try to properly replace the damaged wiring.

Causes of washer malfunction

If the windshield washer does not work, it will not be difficult for an experienced driver to identify the cause of such a malfunction, and even a beginner, after familiarizing himself with the main failures in the cleaning system, will be able to eliminate them on his own.

Mechanical problems

The most important reason, as mentioned above, may be the lack of washer fluid; in this case, you just need to top it up. If it is present, but does not splash in the winter, then perhaps it is simply frozen. In this case, the problem can be solved in one of two ways:

• warming up the engine;
• bringing the car into a warm garage.

After the liquid has thawed, the system will begin to operate as usual, but it is better to drain the water from the tank after this and replace it with an “anti-freeze” one.

Windshield washer design

Correct operation of the washer depends on the performance of the elements that make up its design:

• A pump equipped with nozzles through which the working fluid is sprayed over the surface of the glass.
• Backa.
• Hose systems.

A small motor consisting of an impeller and a wiper seal is used as a washer pump. The functional task of this device is to supply (forced) working fluid to the surface of the car windshield. Of great importance in the efficiency of glass cleaning is the correct orientation of the nozzles in space, ensuring that the working fluid reaches the middle of the glass surface.

Windshield washer: 1 – windshield washer reservoir; 2 – tank mounting bracket; 3 – screw; 4 – liquid level indicator sensor; 5 – tank plug; 6 – injection pump; 7 – hose from the pump to the nozzle; 8 – tee; 9 – washer jets

A prerequisite for the long-term operation of all elements of a vehicle windshield washer is the constant presence of a certain amount of working fluid in the system. Therefore, we strongly recommend that you periodically monitor its (liquid) level and top it up in a timely manner. However, the washer, like any mechanism, sooner or later fails.

Injector maintenance

To ensure uninterrupted operation of the injectors, attention must be paid to them periodically. An extra inspection of the injectors won't hurt. If the injectors have not been turned on for a long time, they must be checked for functionality. Clean and adjust if necessary. In the winter season, it is imperative to use antifreeze washer fluid. Freezing of injectors leads to their wear and premature failure. If you follow the recommendations proposed in this article, then you will not need to replace the washer nozzle on the VAZ 2112 for a long time. And the windshield will be washed as the video shows.

Device Features

There are new and old motors. The latter can be found on Soviet cars, or on VAZ 2107, 2108, for example.

Most cars, including the VAZ 2109, 2110, 2114, as well as foreign cars Mitsubishi Lancer, Pajero Sport or Ford Focus, already use new types of washer motors (pumps).

The main components of the washer are:

• nozzles;
• pump (motor);
• reservoir with washer fluid.

Nozzles are used to supply water to the windshield of a car. Therefore, they should be positioned so that the outgoing stream of liquid hits the center of the headplate as much as possible. The pump supplies water to the tank. By the way, on some cars, wash water is supplied not only to the windshield, but also to the main headlights in front and behind.

It doesn't matter what kind of car you have. It could be a Priora, Hyundai Accent, some Mazda or Toyota

All the washer motors work on the same principle. Although the device, characteristics and appearance may vary.

Pumps supply water or washer fluid. If the windshield washer does not work, most likely the reservoir or the nozzles themselves are broken. They can be replaced or repaired yourself.

If the pump breaks, the task is a little more difficult.

It is important to immediately identify the problem and fix the breakdown. Driving a car, especially in bad weather, when the windshield wiper does not work is dangerous

Causes of malfunctions

Don't rush to blame the engine for everything. It may work, but the windshield wiper does not function for other reasons.

Let's look at the key reasons why our wipers stop doing their job.

• Clogged filter or nozzle. Frequent breakdown. Especially for those who use tap water instead of special washer fluid. To solve the problem, you need to dismantle the devices and flush the system. The work is not difficult, but delicate;
• Supply hoses. They wear out over time, lose their tightness, and burst. Everything is simple here. Remove the old hoses and install new ones. Their price is cheap even on foreign cars;

• Incorrect connection. While carrying out some repair work on the wipers themselves or nearby components, you could disassemble the washer system and reassemble it incorrectly. Check connections and correct errors made during assembly;
• Electric motor and pump shaft. It happens that the connection between them is weak or completely broken. What to do? Right. The element needs to be better secured;
• Motor failure. It doesn’t happen that often, but you shouldn’t rule out this option. Before changing a part, try to clean the motor and its brushes, and get rid of all traces of corrosion. Sometimes it helps. If the repair does not produce results, replacement will help.

Here are the main causes of windshield wiper failure. It is not the most complex mechanism in a car, so you can repair it yourself.

Reasons why car wipers do not work

Remember how annoying it is when your windshield washer fluid runs out in dirty weather? The only thing worse could be a complete failure of the wipers. Let's figure out why the windshield wiper may not work on the VAZ 2110..

The instructions are suitable not only for owners of VAZ 2110, 2111,2112 cars. Similar causes of malfunctions are found on other machines of domestic or foreign production. The only difference is in some details, such as the name of the fuse or the diagram.

1 – windshield wiper electric motor; 2 – washer motor; 3 – steering column switch; 4 – fuse block; 5 – ignition switch; K2 – relay; A – the numbering order of the plugs in the block of the wiper motor; B – to power supplies. So, we noticed that the wipers have stopped working, the procedure is approximately as follows: 1. Check the F9 20A fuse in the mounting block. 2. At the same time, we check the relay for switching on the windshield wipers and windshield washers (install a known good one for testing, check that the relay is not installed on the other side). A faulty relay occurs when the intermittent wiper mode does not work. 3. Poor electrical contact. There can be many options, for example, the wiring has melted, poor ground contact, poor contact in the block with the wires in the engine compartment due to exposure to moisture, faulty mounting block, etc. We check the presence of voltage on the electric motor pads. 4. The steering column switch is faulty. 5. The nuts on the trapezoid have become unscrewed or loosened. For example, a nut securing the crank to the gearbox axle. Check the windshield wiper trapezoid, tighten the nuts. 6. The windshield wiper trapezoid is jammed. Repair, lubricate or replace. 7. The electric motor is faulty or its fuse (separate) has blown. We check the voltage supply. If necessary, we repair or replace with a new one. If the windshield washer does not work, then check:

1. presence of water in the tank;
2. condition of the windshield washer pipes;
3. relay and fuse F9 20A;
4. washer motor.

Let us remind you that if you are not satisfied with the operation of the windshield wiper, then by modifying the washer system as a whole, or separately, for example, increase the cleaning area of ​​the wipers or modify the relay.

Cleaning the injectors

Before replacing the injectors, if they are thoroughly clogged, you can try to revive them. To do this, it is necessary to flush the injectors. The service manual for components and assemblies of the VAZ 2112 car does not indicate how to flush the injectors. But, even for a novice car enthusiast, this procedure is not very difficult. To do this you need:

• Soak the nozzle in white spirit for 3-4 hours.
• Clean the nozzle with a thin soft wire.
• Flush the supply channel with high-pressure water.
• Blow out the channel with compressed air.

If necessary, the procedure must be repeated several times. In particular, on a VAZ 2112 car, washing the injectors does not take much time. And it’s not the price that worries us in this case. Much more important is the knowledge and experience that we acquire in the process of performing these works.

Attention: Do not clean the nozzle with a sewing needle. The tip of the needle may break and completely jam the washer fluid supply channel.

Defective injectors

First of all, the car must be installed on a site convenient for work. Defects of the nozzle are carried out by simply turning it on. Using the steering column switch lever, you need to turn on the VAZ windshield wiper and observe the operation of the nozzle.

List of problems with washer nozzles

• Washer fluid does not flow through the nozzle nozzle at all.
• The washer fluid pressure is very weak.
• The jet of liquid supplied is directed to the side and does not provide complete cleaning of the windshield.
• The pump supplying washer fluid or its motor has failed.
• The washer fluid supply tube is damaged.
• The injector has mechanical damage.
• The injector nozzle is clogged with foreign material.
• The nozzle adjustment is incorrect.

Causes of problems

Attention: In order to quickly determine the area where the defect is located, it is recommended to disconnect the washer fluid supply tube from the nozzle and turn on the washer. If the fluid supply pressure is normal, then the problem is in the injector.

Windshield washer does not work: causes and solutions to the problem

Each element of the car must work efficiently, otherwise operating the car will be quite a difficult task. Many people underestimate such a vehicle component as the washer and the entire windshield washing system, including the wiper. Without the working mechanisms of this unit, it is difficult to imagine operating a car in wet weather. That is why it is best to maintain the washer in working condition and avoid any breakdowns. Otherwise, splashes from the wheels of other cars, as well as rain and snow, will become insurmountable obstacles to your trip.

It often happens that the washer breaks down in the middle of the journey. If the road is wet and cars in traffic splash your car with mud, it is better to stop using it until the problem is corrected. It is often even easier and cheaper to call a tow truck and transport the car to a service station than to try to get to a service station without normal visibility. It is almost impossible to foresee such a breakdown.

The main causes of windshield washer problems

It is necessary to distinguish between the washer system and the wipers. If the windshield wiper blades are operating, driving is possible in wet weather, but dirt will be carried across the glass and can create scratches on the surface. When it rains, only wipers are needed for a normal trip. But if the weather is not too wet, and dirt is still rising from the road, you need a high-quality washer that performs all its functions.

In domestic cars, the system often breaks down in the area of ​​the washer reservoir or the motor that pumps liquid to the nozzles. The outlet tube is attached to the motor using a plastic transition, which tends to break. If this unit breaks down, you will have to replace the entire motor; there is no point in gluing and restoring the old unit. Common problems associated with the washer system on any car are as follows:

• rupture of the hoses through which the liquid flows to the sprayers for cleaning the windshield;
• pinching of hoses and lack of normal fluid supply for the functioning of the system;
• a crack in the washer reservoir, due to which all the liquid disappears within seconds after filling;
• poor quality or loose attachment of the hose to the tank, motor or injectors;
• clogged nozzles, which are used to spray liquid directly onto the windshield;
• failure of the motor and cessation of the flow of liquid under pressure for its normal spraying.
