The main functional task of windshield wiper blades is to ensure systematic and effective cleaning of the windshield and rear window of the car from snow, rain, and various contaminants. Their obvious advantage is the ability to take into account the curvature of the windshield shape and the compactness of the mount itself.
Wipers of almost all brands of cars of the VAZ family, including wipers on the VAZ 2114, have several operating modes. The windshield wiper operates in four modes:
- intermittent, with a short pause;
- first speed (slow);
- second speed (accelerated);
- cleaning with washer.
The rear wiper operates in two modes:
- cleaning without washer;
- simultaneous cleaning with washer.
Optimal size of wiper blades (windshield wipers) VAZ
Long-term use of windshield wipers leads to significant wear, which is reflected in the inadequate performance of their functions.
The first signs that you need to replace wipers of the appropriate size are:
- The appearance of streaks on the windshield and rear window due to several movements of the windshield wiper.
- The work of the wipers is accompanied by creaking and grinding noises.
- Deformed rubber tips.
Very important! If you do not pay due attention to the condition and operation of the wipers in a timely manner and do not promptly replace unsuitable brushes with a similar size, then during snowfall and heavy rain, the visibility of the road surface is greatly reduced. This significantly slows down the driver’s reaction, which can lead to an emergency situation affecting the safety of both the driver, passengers, and other road users.
Possible washer malfunctions
In order for the wipers to work properly, a constant supply of water is necessary. To automate this process, a washer was made. There may be the following reasons for its failure.
- The steering column switch has failed. To check this, you need to close the two contacts located under the steering wheel. Front contact 53ah-w, rear contact 53ah-wh. After this, measure the resistance. In case of low resistance or breakdown, the switch must be replaced with a new one.
- The washer pump does not supply water. It needs to be changed.
- The wire connecting the switch to the pump has broken.
- The injectors are clogged with dirt. They can be cleaned with a sharp needle.
- Relay K3 does not work.
- The hose broke.

As you can see, even simple parts have enough problems and breakdowns. However, following the operating rules will help avoid repairs and increase their service life.
Correct selection of wipers by size for VAZ 2114
To avoid unwanted problems during vehicle operation, experts recommend annual maintenance and, if necessary, replacing the brushes on the VAZ 2114 with ones compatible with the specific brand of car.
Factory symmetrical VAZ 2114 auto wipers have a standard length on each side of the windshield - 51 cm.
But it is possible to supply brushes of other sizes:
- driver's side – 53 cm;
- and on the passenger side - 51 cm.
But if you install 53 cm brushes on both sides, water flows in a thin stream in the middle of the windshield.
On the rear window of this model, the blade size is 30 cm, although some car enthusiasts install 33 cm and this does not create any additional problems. Installing a rear wiper 40 cm long will require expanding the stroke limit. But to ensure that the windshield wiper does not go too low, and also does not run into the glass seals: the motor is removed, then put back, with the obligatory displacement of a couple of teeth.
What's better? Frame or frameless?
In fact, everyone chooses their own, which is why long conversations are held on forums where they do not find a definite answer. We, in turn, will not claim that one or the other is better, we will simply tell you the advantages of one over the other, and you can choose for yourself. Agreed? Then let's go!
Frame wipers
Frame wipers are inferior in appearance, but have greater pressing force against the windshield due to the structure of the rocker arms, which undoubtedly affects the quality of glass cleaning for the better.
But the complex system of rocker arms also has a negative aspect: in winter, in snowy weather, the rocker arms are covered with ice, the wiper becomes motionless and oaky - accordingly, the brushes are poorly cleaned. There is only one way out of this - to warm it up. standing in the cold, clear the ice from the wipers until the rocker arms move freely.
Therefore, for winter they came up with frame wipers with closed rocker arms. In other words, the entire skeleton of the wiper is hidden in a plastic casing, where snow and moisture do not penetrate - accordingly, the rocker arms are always movable and the wiper cleans well. But this system also has a small drawback - at high speed, due to the “winged” structure of such wipers, the downforce on the windshield noticeably drops, which negatively affects the quality of glass cleaning.
Another advantage over frameless ones is the ability to change cleaning tapes. In frameless wipers, the tape does not change, but the brush assembly does.
Frameless wipers
The appearance of these wipers blends harmoniously with any car rather than the frame frame skeleton.
These economy segment wipers must be selected according to the make of the car, because Each car has its own windshield shape, and accordingly, the windshield wiper has its own bend. Therefore, with cheap wipers, it often happens that the brush does not press well on the passenger side, and therefore the dirt is not cleaned. There is nothing you can do about such brushes, just replace them with quality ones. The premium segment promises us to work perfectly on any car, the main thing is to choose the length, but the price of such brushes is 1000 rubles.
Another advantage of frameless ones is that they are easy to clean from ice in winter; just bend the wipers a couple of times and all the ice will fall off.
Another advantage of such wipers is good aerodynamics. Those. their downforce does not decrease as speed increases.
I hope everything has become clear to you and you will make the right choice. We also recommend that you read the article: Which windshield wiper blades should you choose? In it you will learn how to choose the right brushes, what you need to know, and which companies you should give preference to.
What happens if you choose the wrong brush size?
When choosing auto windshield wipers for a VAZ, it is imperative to pay due attention to their size, since a deviation of even 10-15 mm is very important.
Even a slightly increased brush size, in comparison with the manufacturer’s recommendations, can contribute to the manifestation of negative aspects during operation, namely:
- the glass is poorly cleaned even after prolonged operation of the brushes - the incorrect length of the brushes significantly reduces the clamping force of the wiper directly on the glass, so the quality of its cleaning will decrease, this is especially noticeable when using frameless windshield wipers;
- such wipers can touch the rubber seal on the windshield, thereby causing damage to it, while they come off the working surface, leave gaps with uncleaned stripes and do not provide high-quality cleaning;
- extended windshield wipers will touch each other, which means they can block their operation and deprive the driver of the required field of view on the highway at the wrong time;
- a large brush sometimes even touches the edge of the driver's door, causing some damage to the body of the car, and by knocking on the pillar, it simply irritates the driver and distracts from the situation on the road.
The size of the brush on the VAZ 2114 that is too small than what is provided by the manufacturer significantly reduces the cleaning efficiency, as it limits the area of glass cleaning (the central part of the windshield will not be captured by the brushes). In addition, during rain, the short length of the wipers favors the appearance of flowing water and the appearance of islands and streaks of dirt.
Replacement
The replacement process is relatively simple. Doesn't cause any problems. It includes the following main steps:
- it is necessary to place the brush in a vertical position - perpendicular to the wind stack (it must be fixed);
- Next, the plastic fastener is compressed on both sides - after which the brush just needs to be pulled towards the hood.
If everything is done correctly, the clamp should come apart without much effort. After which you can begin installing the new wiper. Plastic clamps and fasteners are made of fairly fragile plastic. Even famous brands are guilty of this. Therefore, all actions must be performed carefully, without sudden movements. Otherwise, small parts may be damaged. This will cause installation to fail. You will have to purchase new fasteners.
Modern auto wipers VAZ 2114
Leading manufacturers especially recommend modern frameless brushes VAZ 2114 to car enthusiasts. Their advantageous feature:
- more dense, uniform pressure to the glass;
- less restriction of field of view for the driver;
- high-quality cleansing without streaks in both directions;
- no noise from air flow.
Helpful advice. Of great importance for the safe movement of the VAZ 2114 is the exact match of the brush sizes required by the manufacturer for the corresponding type of car. This is especially important in snowy winter, when the outline of the road is practically invisible.
Although frameless wipers have a slightly shorter service life, they are considered the best, and therefore cost a little more.
A very important factor in safety and comfort while driving a car is the removal of dirt and water from rain from the rear window. The rear wiper of the VAZ 2114, with a speed regulator, which is located inside the car, turning in both directions, copes with its functional tasks perfectly.
Frame
Frame brushes are a skeleton to which a cleaning rubber band is attached. In other words, rocker arms extend from the wiper arm (there are 2, 3, 4 of them depending on the model), to which a cleaning tape is attached, which is in free circulation (can move forward and backward). Each rocker arm is movable, so it fits tightly to the glass.
Thanks to this design, it is not necessary to replace the entire brushes; you can only get by by replacing the cleaning tape. This is a plus, because its cost compared to a set of new wipers is noticeably different in favor of the former.

Trapezoid repair
If the wipers on a VAZ 2114 work slowly, this indicates the need to repair the trapezoid. Although in reality it cannot be repaired, you just need to replace the failed element.
Replacing the trapezoid
Replacement will be required in case of mechanical damage. The procedure is quite simple, but here you will have to follow a certain sequence.
- Disconnect the wires under the hood that connect to the fuse box.
- Remove the protective cover that covers the heater fan.
- Remove the heater (stove) filter.
- Turn off the heater motor. It simply slides to the side; there is no need to dismantle it.
- The cover is removed from the wiper.
- Under the rubber protection cover there is a nut that holds the windshield wiper. You need to lift the cover a little and the nut will be easy to unscrew. Remove the wiper.
- Remove the rings and gaskets from the wiper shaft.
- Carry out a similar procedure with the second wiper.
- Under the hood, remove the bolts that connect the trapezoid to the body.
- Remove the fuse box and the stove motor, or unscrew the gear motor from the trapezoid, after which the motor and trapezoid are removed one by one. These are two ways that will allow you to get a failed trapezoid.
Common problems
It is not uncommon for car owners to encounter a situation where the wipers on a VAZ 2114 do not work properly. The causes of the problems may be different, so you should carefully examine the breakdown, and then take appropriate action.
Typical faults include:
- They work constantly;
- The windshield wipers may operate on their own, even though the driver has not turned anything on or pressed anything;
- May work too slowly;
- Spontaneous switching occurs.
