Why is the nozzle not spraying?
The washer pump fuse has blown. You can find out the location of the fuse link that protects the electric motor circuit from the repair and operation manual. Very often, on the plug covering the mounting fuse block, the manufacturer, using graphic symbols, indicates the number of the fuse link and the consumer whose circuit it breaks in the event of a short circuit. If you have to change the fuse frequently to operate the washer, there is a short circuit in the circuit.
Instead of a burnt-out insert, install only a fuse of the appropriate rating. Installing fuses designed for high current can result in a vehicle fire.
- The pump has failed. A breakdown can be caused by blocking the rotation of the impeller wheel with dirt or corrosion. The power of the electric motor is not enough to rotate the armature shaft of the electric motor. In some types of construction, corrosion and dirt block the rotation of the motor armature.
- The washer nozzle sprays poorly or does not spray at all, as the nozzle channel is clogged. The cause of the malfunction is corrosion of the channels inside the nozzle and debris entering the tank.
- Motor circuit malfunction. Failure of the steering column switch, an open circuit due to damaged wires, or the formation of oxides on the terminals are the most likely reasons why the windshield washer does not work.
- The hose has torn, broken, or jumped off the pump fitting. Carefully inspect the transition of the hose from the engine compartment to the hood, the secure fit of the hoses to the fittings of the injectors and washer pump.
- The washer fluid in the reservoir has frozen.
Principle of operation
The windshield and rear window cleaning system is based on an electrically driven pump. The armature shaft of the motor is connected to a paddle wheel, which, when rotated, supplies washer fluid through hoses to the windshield washer nozzles. The sealing collar prevents washer fluid from entering the electric motor. It is the leakage that becomes the main reason why the windshield washer pump does not work. Water and glass washer fluid getting inside start the corrosion process, deteriorating the quality of the contacts and increasing the resistance to rotation of the pump armature.
A DC motor is used as a motor. There are at least 2 types of design:
- the pump body is also the body of the electric motor, so permanent magnets are attached to it;
- A separate motor is used, which is assembled and installed in the windshield washer housing.
In most systems, separate pumps are installed for different circuits. But in some cars, one electric motor can wash both the rear window and the windshield. In this case, the direction of fluid supply depends on the polarity of the voltage supplied to the electric motor. For variable supply of liquid in different directions, a check valve is used in the design.
Finding the cause of the breakdown
To determine the breakdown due to which the glass washer has stopped working, use the method of elimination.
- Turn on the windshield washer (there is no need to start the engine, just turn on the ignition). Listen for a buzzing sound coming from where the tank is installed, indicating that the electric motor is turning on. If the motor hums, look for the cause of the failure in the hoses and injectors.
- The electric motor does not turn on. Disconnect the pump connector. If there is enough space around the reservoir, the pump can be checked without removal. To check why the motor is not working, it is enough to directly supply power to its contacts from the battery. To do this, you will need two pieces of wire, one end of which is attached to the positive and negative terminals of the battery. Using the mating parts of the wires, briefly touch the terminals of the windshield washer motor. If there is no immediate reaction, apply voltage in a mirror manner (you can avoid this error if you first study the circuit diagram for turning on the pump on your car). If the motor works, the washer does not work due to problems in the control circuit. Otherwise, the reason is in the pump itself.

The problem is known to those owners of domestic barns who use a rear washer and wiper. We turn on the rear window washer, and while the liquid runs through the pipeline to the wiper, the wiper stays dry. The problem is not new, a foreign manufacturer (thinking about the consumers of its products) has been equipping cars with the appropriate valve for a long time, unlike our domestic manufacturer, which, on the contrary, for some reason stopped installing an element that was so necessary in terms of comfort and cheap (but it did!)...

You can, of course, look for an imported valve at a dealership or buy a new one at a foreign parts store, but Russian car enthusiasts know of several cheaper options.
The compact option is a valve for an aquarium pump, there are several varieties, sold in pet stores. Not all aquarium valves are created equal; some do not hold liquid back well and bleed it back into the tank quite quickly.

I need to experiment, but I was sorry for the time and money for this.
It costs about fifty dollars, it looks something like this: The option is the simplest and cheapest - it’s called a “fuel check valve”, catalog number 2108-1156010-01. Installed on carburetor Samara and 10th family, in the return fuel line. Installation takes 1-2 minutes, the liquid does not leak into the tank at all, but there is a slight resistance in the forward direction (the motor easily overcomes it).
It costs 30 rubles, it looks like this: The reliable and most correct option is washer valve 2108-09 (2802.3741), catalog number 21080-5208550-00. When de-energized, the valve is closed, when energized (12 volts) it is open.
One terminal of the valve is for ground, the other terminal is for the plus of the washer motor. When open, flow resistance is minimal. An ideal option, I would even put it on a windshield washer, maybe closer to summer, when it gets warmer... Price 50 rubles, appearance: I didn’t want to mess around with the wiring in the cold, even in the garage, so I settled on the second option, with the eight fuel valve

I installed it under the hood next to the reservoir.
The only difficulty was to put the stiffened hoses on the valve fittings; I had to warm them (the hoses) with a lighter. Now the washer fluid flows immediately after deflecting the lever and the wiper makes the first stroke on a wet surface. A small minus has emerged - when driving up a hill or during sharp acceleration, a few drops from the tube fall onto the rear window, drying and leaving marks

It's a small thing, but unpleasant.
Conclusion - the valve should be placed inside the spoiler (will it fit?), directly in front of the peeper, this is where a small direct resistance of the valve comes in handy - it will not allow liquid to drip. Issue price: 35 rubles

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.
How to remove and wash injectors
The windshield washer nozzles are held in place by plastic clips. To remove the injector without damaging the body, check its number in the original spare parts catalog. By finding a photo of the injector by number, you will see exactly where the latches are located. You can remove the nozzle with a thin slotted screwdriver.
For cleaning, you can use a needle smaller than the diameter of the sprayer hole. We recommend that you first leave clogged injectors in a citric acid solution for some time. After soaking, the deposit can be removed using carburetor cleaner or compressed air.
Good day.
The rear window washer does not work. It’s like a janitor cleaning glass, but without the liquid. What could be the reason?

Will AIRBAG not work when disassembling the casing? And what kind of cladding fastenings are there? I'm afraid I'll tear it off and then not deliver it
I think it’s the hose under the casing, how to disassemble xs
Will AIRBAG not work when dismantling the trim to check the rear wiper hoses? And what kind of cladding fastenings are there? I'm afraid I'll tear it off and then not install it.
I have the same problem)
Perhaps the hose that goes to the back door has fallen off. This happens often.
It turns out that there is a hose somewhere under the casing?
Every car has a windshield washer. In other models it is not even present in a single copy. For example, a washer can moisten not only the windshield, but also the rear window, and even the headlights.
It is foolish to underestimate the importance of this mechanism. After all, clean glass is the key to confident and safe driving in comfortable conditions for the driver.
Unfortunately, due to frequent use, the washer may break, which will present a very unpleasant surprise to the car owner. Problems with this device can be caused by various reasons. And in any case, they should be eliminated as soon as possible.
Rear window washer repair
On many domestic hatchback and station wagon cars, a problem with the rear window washer quite often occurs. And it lies in this: when you press the water supply lever, water begins to flow not onto the glass, but directly into the interior onto the rear parcel shelf. In this article I would like to talk specifically about the Lada Kalina Universal; I think that there are practically no owners left who have not encountered this breakdown.
When this happened for the first time with my Kalina, at first I thought that it would not be so easy to do everything, but in fact everything turned out to be easy. It is enough to open the rear door - the trunk lid, and unscrew the plastic cover of the brake light. It is under it that everything we need is located.
This may require a special screwdriver, but a regular Phillips head screwdriver will suffice. After the lampshade is unscrewed, remove it and gain access to the rear washer system. If you also have water pouring into the cabin, then the reason for it all is a hose that has come off the windshield washer nozzle. Most likely it will not be visible. In order to get it, you need to stick your fingers into the largest hole and pull out this hose.
Now, to prevent this problem from occurring again, you need to fix the hose. I did this: I wrapped a little electrical tape around the edge of the nozzle, heated it with a lighter and put on the hose, and pressed it to the trunk body with a piece of vibroplast.
After that, we put the lampshade in place and screw it in, there shouldn’t be any more damage like this. From my own experience I can say that I have already driven about 20,000 km after this procedure and have no complaints. I hope I helped someone with the issue of rear window washer on Kalina.

How does the washer work?
To talk about what can break in this device and how to fix it, you need to figure out what parts this device consists of. I must admit that it is quite simple to put together.
Tank
The first link in the glass wetting process chain is the plastic tank. In most cars it is located under the hood. However, there are also cars in which, to get to the water tank, you have to climb under the wing.
There are tanks of different capacities. The most common ones are those whose volume reaches 2.5–5 liters. It seems that this is not much, but this amount of liquid will last the driver for a long time. Water is poured into the tank. That's where it is stored.
Injectors
A thin branched tube is attached to the tank, which stretches to the nozzles. The nozzles or sprayers are installed opposite the glass. Water splashes out of them in small doses, from where it is rubbed over the surface with brushes.
Pump
How does water flow from the tank to the nozzles? A small electric pump is responsible for this. It is powered by a battery and uses an impeller to pump liquid from the tank to the outside.
The windshield washer motor is perhaps the most important element of the washer system and its failure leaves the glass without the ability to wet.
What in the washer can break?
If the windshield washers do not work, it means that a failure has occurred in one of the sections of the system described above. Let's look at what problems with the glass washer may be associated with.
Pump
The pump motor is the part of the washer system that wears out very quickly due to frequent operation.
Unfortunately, you can understand that something is wrong with this device only when water stops flowing to the nozzles. Otherwise, it does not show its malfunctions in any way.
Pump repair method:
Two common ailments can affect the motor:
If corrosion of this device is your case, do not worry. Experienced motorists can easily cope with it with a simple eraser.
But if this mechanism is erased or broken, it will have to be pulled out and replaced with a new one.
You can understand that the pump is the cause of the problem by the absence of a characteristic sound. If you press the washer lever and do not hear the usual buzzing sound, it means that the pump motor is not working.
Often windshield washer malfunctions are associated with the breakdown of this particular part. We'll tell you how to replace it a little later.
Blockage
Also, water may stop flowing to the nozzles due to blockage. The fact is that the tubes through which the liquid flows are very thin and the debris that accumulates in them can cause obstruction. To combat this defect, the system will have to be flushed and possibly purged.
Torn hoses
Another reason could be that the hoses have lost their integrity. If the tubes become leaky, water will not get from point A to point B, just like if it is clogged.
No current
And another common reason is lack of nutrition. Check that the pump and accumulator shafts are securely fastened. Perhaps the motor is simply not receiving energy.
Rear window washer Kalina
Most Kalinas, especially hatchbacks and station wagons, have one unpleasant disease (the rear window washer hose frays over time, dries out and eventually breaks. The biggest problem with this problem is that water from a torn hose when using the washer can get onto the ceiling lining and create ugly stains there.
I once noticed that when I turn on the rear washer, water does not flow, although the motor is new and there is enough fluid in the reservoir. I press and press the petal, still nothing happens (It immediately became clear that something was wrong with the hose, so I went to look at the corrugation on the tailgate.
Thank God that the water did not leak onto my ceiling trim, otherwise I would have had to clean it out in a heap. The worst thing is that this hose runs through the entire cabin and you can’t just get it out, so some car enthusiasts don’t bother, but simply buy a short hose with a fitting and connect the old end to the new one. I don’t like this method, because the old hose may break again and the fuss will start again.
It’s better to do everything at once and in a normal way, then there will be fewer problems. I ordered a new hose from Yulsun, and I received the following story.
I ask the guy who is handing out the goods: “What kind of crap is this?” And he: “I don’t know what they ordered, that’s what came.” Damn, I ordered a long hose, but what I received was nonsense, but it cost about 50 rubles, so I didn’t argue, I kept it for myself. I went to a regular auto parts store and said to the lady behind the counter: “I’d like a washer hose for the viburnum, please.” Okay, he says, how many meters? God knows how many, I thought they were already measured out. I looked on the Internet, the length of Kalina in a station wagon is a little more than four meters, but this is from bumper to bumper, and the hose goes from the top of the tailgate to the tank. The tank itself is located near the right glass, and there is a decent distance to the front bumper. “Well, give me 5 meters!” I think it will be enough, it will even remain. The meter was charged for 50 rubles at a cost, and okay, I paid and, happy, went to the dacha to install it.
Reanimating the washer system
How to replace the motor?
Unfortunately, this part is quite difficult to repair. And often replacing a windshield washer pump is even cheaper than fixing an old one. Therefore, it is better to immediately order a new part and not have to worry about repairs.
Replacing the washer pump:
Replacing the device is easy:
- Before you begin replacing, remove all remaining fluid from the reservoir.
- Locate the contact connecting the pump to the battery. Carefully disconnect the power.
- The next point is optional. You can disconnect the tank by unscrewing the bolts that secure it. However, if manual dexterity allows you to manipulate the fixed tank, you can do without dismantling it.
- Remove the electric pump from the tank and unscrew the tubes.
Attention! Remember where and which hose was screwed on. In the future, they will have to be placed clearly in their places.
- So, now we take out a new pump and connect it to the system.
- Screw the tubes back into place.
- If the tank has been dismantled, put it in place and tighten the bolts.
- We connect the contact from the battery so that the motor has something to power from.
- Fill the water back.
Then press the washer lever. If there is a buzzing sound, it means the motor is running.
How to clean injectors?
For washing, prepare a special caustic solution. To do this, take purified water without chlorine and add vinegar. The ingredients must be mixed in a one to one ratio. Stir the resulting liquid well.
Pour the solution into the tank. Press the washer lever. It's okay if no water gets on the glass. The main thing is that the liquid reaches the blockage. Leave the system in this state for two hours. After that, try pressing the lever again. If water appears, drain the caustic solution and rinse the tubes with distilled water.
If water does not flow, but you are sure that the cause of the problem lies in a blockage, press the lever again and leave the acidic liquid for another two hours, then check again.
Replacing the rear window washer hose on Kalina
One of the problems with viburnum hatchbacks and station wagons is a breaking water supply hose to the nozzle on the rear window. Last year's hasty solution to the problem turned out to be short-lived; the hose began to pop out of the connector.
I didn’t buy a standard factory hose, I took a silicone one, 40 rubles per meter. It took 7.5 meters, but I took 10 because... I didn’t know how much I needed.
It is necessary to remove the passenger's sun visor, the interior light, the passenger handle above the head, both trims of the A-pillars (to remove the front panel trim), the trims of the rear pillar of the rear right door and the trunk pillar, and partially unscrew the panel for the rear column. And also partially remove all the seals. All this is needed to free the edges of the ceiling lining and have access to the hose passage cavity.
We release the broken hose from the mount under the ceiling near the rear door
A few days ago there was a problem with my Kalina, but I’m only writing today, since just a few hours ago I fixed this problem. When I pressed the rear washer lever, water did not flow through the nozzle, but it did not leak into the cabin as it did before.
Then, when I pressed the lever for a long time, for some reason I accidentally got out of the car and went to the trunk. And then I see that there is a puddle of anti-freeze behind me. If there were problems before, it was mainly due to the hose coming off the washer nozzle. And this time it was a little more serious. In general, more details below.
When I unscrewed the additional brake light, everything was fine there, and the only place where I could get easy access to the hose was the rubber casing in which the same hose and electrical wiring pass. It was from there that I began further searches, and after I managed to pull out this casing from the holes in the cover, the following picture was visible:
