How to remove the rear wiper blade - all about the car

Every driver of a vehicle knows that good visibility is the key to safety on the road. It is thanks to the so-called wipers that the rear and windshield are kept clean in adverse weather conditions. But everything eventually wears out and needs to be replaced. This happens with car windshield wipers when they stop performing their full function. An experienced car owner knows that rear window wipers wear out much faster, and accordingly, they need to be replaced more often. It's not difficult to do this yourself. At the same time, you need to ensure that the purchased model of the product fits your car...

Types of rear window wipers

The windshield wiper device is a metal arm connected to a rubber surface. The brush is fixed on the lever with a special holder with a plug.

1. Frame brushes are equipped with movable elements called rocker arms. They fix the cleaning surface to the windshield. However, such wipers have a main drawback - hinged joints. Precipitation can cause the windshield wipers to malfunction. Also, a loose fit of the rubber element to the glass surface reduces the quality of the wipers.
2. Frameless windshield wipers have a spring, so the rubber surface fits as tightly as possible to the windshield. This promotes better glass cleaning and increases service life. A distinctive feature of such wipers is their curved shape. You can see frameless models on many cars. They look good, do not reduce the aerodynamics of the body, are not as susceptible to icing and do not interfere with visibility. But there is one drawback - it is impossible to change only the rubber band on the brush, so you have to do a complete replacement. Also, in most cases, a frameless windshield wiper is selected for the appropriate vehicle based on parameters such as the angle of the windshield and the length of the blade itself. Attention to car owners who want to replace the rear frame wiper with a frameless one: despite the fastening in the form of a simple hook, such a replacement is almost impossible. The reason lies in the fact that the leash is located very close to the glass, which does not allow installing a frameless model, which is higher at the ends than the frame one.
3. Plastic rear windshield wipers are essentially blades with a smooth plastic frame. A wiper of this type is installed using a special mount on a plastic leash, as if being its continuation. This type of model needs to be selected more carefully to ensure it fits exactly.

General recommendations

To determine whether your windshield wiper blades need to be replaced, you need to inspect them for damage. As rubber ages, it loses its ductility and cannot perform its intended purpose well. If the operation of the wipers on your car leads to the appearance of streaks on the windshield, we advise you to think about buying new blades and then replacing them.

It is necessary to understand that replacing wipers means replacing only a small component of the windshield wiper. Car wipers are made of three main elements:

• the lower arm, which starts from the base of the windshield;
• a metal holder that is connected to the lower arm;
• brush made of rubber.

It is the brush that wipes the windshield. This item is a consumable item, so it is replaced quite often.

By the way, you can replace the wiper rubber bands, but not the entire blade. Read more about this in our article for those who do not want to overpay - https://avtopub.com/kak-snyat-i-zamenit-dvorniki-shhetki-stekloochistitelya/

Before removing the windshield wiper blades, it is necessary to purchase suitable replacement elements in advance. This is not difficult to do - you just need to measure the dimensions of the previously installed brushes using a tape measure. Another option is to remove the wipers and take them to an auto shop.

Remember that in most cases the sizes of the right and left windshield wipers are different.

As a rule, the cost of windshield wiper blades ranges from 200-700 rubles. Sometimes they may cost more, but this is true for original products.

Options for replacing rear wipers

If your car's rear brush is worn out or malfunctioning , you can:

1. replace it with a new original one,
2. replace with an analogue of the original,
3. Just replace the cleaning tape.

To replace the rear brush with an original one , we simply purchase it at any auto store or place an order there and install it. As for the selection of non-original ones, many of the manufacturers can offer alternative models. In this case, most likely, the design will need to be slightly modified in order to install it properly. Sometimes, only the rubber part of the brush wears out. Then you can simply replace this cleaning tape with a new one.

On different models of cars, rear wipers are installed differently. Therefore, there is no single installation method. But everything is identical.

Here is one way to remove the rear wiper blade and replace the wiper. We remove the cover from the mounting axis of the windshield wiper arm, which is attached with latches. Then we lift the leash from the glass. At the same time, we turn the wiper itself perpendicular to the glass until the latch reaches the stop. Now carefully remove the brush from the clamp. To install a new one, we do the same thing, only exactly the opposite. The elastic band can be changed simply, without removing the structure from the leash. To do this, you just need to pull out the rubber band along with the spokes from the central part of the windshield wiper. A new rubber band is attached in the reverse order.

Why do wipers start cleaning glass worse?

If the wipers start to work worse, do not rush to throw them away and replace them with new ones.

Before you can revive your old windshield wipers, you need to understand what caused them to perform poorly. The main reasons are:

• The windshield wiper is not seated correctly. This manifests itself in the form of stripes on the windshield when the wipers are operating. Most often, this problem can be solved by simply checking the grooves in the rubber part of the brushes. Dust, dirt, water or small pieces of ice are constantly clogged into this place. You need to clean the edge of the rubber band. If the problem remains, the rubber may have already worn out and cracks have formed on it; in this case, all that remains is to replace the torn tape.
• Windshield deformation. If the windshield has mechanical damage, this leads to rapid wear of the blade edge. The correct shape of the edge grinds down and becomes oval, which affects the cleanliness of the glass.
• Dirty windshield. When working on dry or very dirty glass, cracks appear on the rubber part of the brushes. During the cold season, the windshield is often covered with ice and many people turn on their windshield wipers to remove it, thereby damaging the tires. In the summer, it could be tar, stuck insects, or just a dried piece of dirt. Before you start driving, you must manually clean the glass from a large layer of dirt, ice, or get rid of insects using special means.

Traditional methods of restoring the operation of windshield wipers

Keep in mind that if the wipers have already completely worn out and cracks and grooves have formed on them, then these methods will not help you.

Obviously, in most cases of poor performance of windshield wipers, it is the rubber part that is to blame. As it is used, it becomes woody, becomes less flexible and elastic. The task is to return this elasticity to it. Here are some ways:

1. White Spirit. An accessible and inexpensive product. It lubricates the brushes, removes grease and dirt, making them easier to glide across the glass. You need to take a piece of rag, moisten it with liquid and wipe the rubber part of the wipers. Allow to dry, then check functionality. The procedure can be repeated 2-3 times.
2. WD-40. Almost a universal remedy. It will perfectly clean the rubber and make it soft. Spray the rubber several times along its entire length and let the liquid absorb. After drying, repeat several times.
3. Hot water. Perhaps the simplest and most accessible method, it is especially effective in combination with the others. You need to immerse the brushes in boiling water for 30-60 minutes, this will remove all deposits and soften the rubber.
4. Petrol. Here you need to act by analogy with hot water. In addition to the positive softening effect, gasoline will also degrease the entire surface.
5. Manual adjustment. If it is obvious that the rubber part is in order, but uncleaned stripes remain on the glass, you need to try to bend the frame, which could be deformed. The method is only suitable for frame “windshield wipers”.

If the windshield wipers are not cleaning well due to greasy dirt on the windshield, add a couple of drops of good dishwashing liquid to the windshield washer reservoir. Its fat-soluble properties will help quickly solve the problem. In some cases, cutting the rubber part of the wipers helps. How to do this - watch this video:

These simple folk methods in most cases help extend the life of the wipers. Windshield wipers require attention and care, like the entire car as a whole.

It is important to maintain them in a timely manner, eliminate malfunctions and avoid errors in operation. Only in this case will they properly perform their important function. Also, a lot depends on the manufacturer, so it is better to buy only proven well-known brands

Why are car wipers needed?

Windshield wiper blades have another popular name - “wipers”. With their help, the car driver has the opportunity to drive his vehicle in any weather. Replacing windshield wiper blades will be discussed below. Almost every driver has encountered problems driving in rainy weather. Especially if a car is driving towards you at high speed, spraying mud on your windows. In order to clearly see the road, scientists developed car wipers.

Mount "DNTL1.1"

This type of mount was introduced in 2013. Called according to Bosch markings - DNTL1.1 or GWB044. The first car with such a mount is the Lexus NX. Buy brushes with DNTL1.1 fastening. Learn more about the “DNTL1.1” mount and video installation instructions.

Replacement indicator

Today, modern wiper models are equipped with a special mark that allows you to determine when the windshield wiper blades need to be replaced. Most often, such products have a special mark in the form of a square or circle on the body of the model itself. It is usually applied with special paint, so when installing such a cleaner, first remove the protective film from it.

As a result of exposure to ultraviolet radiation and bad weather conditions, the paint will change color, which will indicate the need to replace the wiper. In this case, such an indicator will not respond to mechanical damage and cleaning liquids.

How often should wipers be changed?

No one will give you a definite answer, but on average about 1–2 times a year. Many car enthusiasts start replacing only when they are unhappy with the unproductiveness of their work. The service life is influenced by many factors:

• use of chemicals in car washes;
• negative temperature effects;
• price factor;
• quality of windshield wipers;
• in winter, the road is covered with salt, sand, etc. and this has a destructive effect.

As a result of all these influences, the rubber quickly “hardens”, and accordingly, the fit is significantly reduced. This is also affected by the condition of the hinges (applies to frame wipers).

When the glass is cleared with only 3-4 strokes, and the wiper operating area on the glass becomes clearly visible, it means it’s time to change it. This problem does not exist with brushes with a wear indicator (special paint is applied). When its color changes, it means replacement is necessary. Approximately such a check should be done once a year.

Signs of Wiper Blade Wear

Specific signs will help you understand whether your windshield wiper blades need to be replaced. Pay attention to the following points:

• During cleaning, stripes and dirty stains appear on the glass;
• large unrefined areas;
• the appearance of vertical and narrow stripes on glass.

Replacing windshield wiper blades yourself is quite quick. Many car owners are afraid of breaking something, and in vain. In fact, it is very easy to remove and replace the wipers yourself. You will only need a little free time and a minimum amount of knowledge and skills.

Replacing windshield wiper blades involves removing the old products and installing new ones. A very important replacement rule is to buy a product model that is ideal for your car. After all, very often different “wipers” differ in length. Be sure to take this parameter into account when purchasing.

Procedure for replacing windshield wiper blades

1. We move the lower arm away from the windshield of the car. To do this, it must be lifted by the place where this element is attached to the wiper holder made of metal. It must be brought to a stable position. Note that a spring is used, so the lever must be raised all the way. Otherwise, it may return to its original position, and in some cases this may lead to damage to the windshield.
2. We disconnect the windshield wiper blade, which has already served its purpose. Pay attention to the joint where the brush blade connects to the holder. In this place there is a plastic plug that holds the blade. You need to press this plug and disconnect the brush (photo below).

3. In some cases, to replace wipers, it is necessary to change the position of special flags that hold the wiper blade in place.
4. Be sure to ensure that during the procedure for replacing rubber bands on the wipers, the lower arm does not hit the windshield, as the consequences can be extremely sad. Sometimes it is better to use a towel to protect the glass, which will help avoid unforeseen situations.
5. Next you need to replace the wiper blades. They need to be inserted into the holder and the new rubber element must be carefully turned so that the hook takes its place. Then the hook must be secured and the entire wiper must be returned to its base position on the windshield.

6. We repeat similar steps with another windshield wiper. Don't forget to check if you have made a mistake when choosing the right and left sides.

For clarity, we also publish a video on how to remove windshield wipers (wiper blades) and replace them easily and simply:

Step-by-step replacement instructions

To replace the wipers you should follow these steps:

• The lever is placed vertically and then removed from the glass itself. Do this very carefully. After all, if it jumps out, there is a risk of breaking the machine glass.
• After the first step, open the cap by pulling the brush down. Remember to hold the holder very firmly while performing this step.
• Now take the new product prepared in advance and put it on the knitting needle, while closing the plug itself. Try to level it as much as possible by pulling it down.

That's all, the new windshield wiper blade is installed, so you can safely drive the car and not worry about poor visibility.

Mount "VATL5.1"

This type of mount was introduced in 2016. It is called in accordance with the Bosch marking - VATL5.1 or GWB046 The first cars with this mount are Dacia / Renault Duster and Kaptur. Buy brushes with VATL5.1 mount. Learn more about the “VATL5.1” mount and video installation instructions.

How to remove frameless wipers

Before removing the frame wipers, thoroughly clean their mountings. Only after this can the device itself be dismantled. You will have to do the following:

• carefully unscrew the mounting pins;
• now take out the brush body;
• carefully remove the rubber plugs of the bolts;
• unscrew the bolts yourself.

Pay special attention to the process of unscrewing the bolts. This must be done extremely carefully, because most often they are connected directly to the motor that sets them in motion. If you accidentally damage this mechanism, then even the highest quality and most expensive wiper models will be useless.

How to protect brushes from wear

Not every driver wants to change wiper blades every six months. Therefore, to do this, it is necessary to monitor their condition and fulfill some requirements for their operation.

Before you start cleaning the windshield, you must first moisten it with water from the sprayer. If the barrel is empty, you can use a plastic bottle or snow. The movement of rubber bands on dry glass can cause damage. There is a lot of dust and sand on the windshield, especially on the rear window. When a dry rubber band passes over them, abrasions and cracks may form on its surface. Of course, this does not happen after just one time, but it is a fact.

From time to time the wiper needs to be lubricated or washed with water. And this applies not only to the mechanism, but also the rubber band must sometimes receive a share of lubricant. In winter, special care is required. If you leave the car for an indefinite period of time in the open air (not in a warm garage), then it is necessary to move the wipers away from the windshield. In severe frosts, the rubber bands freeze to the glass. And if at this time you need to use the car, then do not even think about turning on the glass cleaning. This can lead to premature wear of the motor and brushes. When cold weather sets in, it is necessary to replace the washer fluid with antifreeze. This will not only preserve your wipers for a few more seasons, but will also save your fluid reservoir. Since ordinary liquid freezes and causes the tank to crack. High air temperatures and direct sunlight on brushes reduce their service life by half. If you don’t want to buy new brushes after the summer, don’t be lazy to remove them from your car. The withdrawal procedure will take you a couple of minutes and will save you several hundred rubles. You can get into the habit of wiping the glass while refueling your car or every time you use it. The most vulnerable part of the (frame) wipers is the hinges. They're worth keeping an eye on. When dust gets on them, they cause corrosion and premature wear. The hinges must be lubricated with any means. Otherwise, the windshield wiper will have to be replaced. It is not recommended to use the wiper when there is a layer of snow on the windshield. It is better to sweep it away by hand or with a scraper. And only after that, turn on the wiper to clean the wet glass. Do not turn on the wiper when the glass is covered with a layer of ice.

Rubbing the rubber bands against the surface will lead to the appearance of cracks and cuts, and this, in turn, #8212 will lead to poor cleaning of the front or rear windows. Before purchasing new items, pay attention to their condition. Carefully check their surface for damage.

Remember, the cheaper the wipers, the worse their quality of work. It’s better to pay once, but drive with normal windshield wipers for more than one year.

Replacing rubber bands on windshield wipers

Even if you have never done this, removing them yourself will not be difficult.

It is important to consider that there are three types of wipers and several types of fasteners that attach the elastic to the base (ribs). Prepare the necessary tools - pliers, knife and scissors

Replacing rubber bands on wipers is quite simple and does not take much time.

The windshield wiper arms must be raised (away from the windshield). Next, you need to stick out the old worn rubber bands. To do this, we find their place of attachment to the guide arms and disconnect them using pliers

It is important not to overdo it with the clamps. They need to be bent a few millimeters (2-3)

Otherwise they may be damaged. Each elastic band is detached along with the edge on which it is located. Some sets include not only elastic bands, but also these ribs. If they are, by all means, use them. If not, use the old ones. The new elastic band must match the size of the old one. Therefore, if necessary, cut it to size. The new part is inserted in place of the old one (into the grooves), after which the mount is fixed. The ribs are installed in their original place.

Since you had to replace the wipers, you can at the same time lubricate the entire mechanism or rinse it with clean water. You can make driving a car more comfortable. To do this, it is enough to install normal windshield wipers.

Installation of new frameless products

Replacing frameless windshield wiper blades is a procedure that must be performed with extreme caution, so for the first time it is recommended to watch how professionals will perform the replacement, and only then do it yourself. But still, if you decide to do it yourself, then follow these steps:

• First, you will have to install new rubber gaskets under the wiper bases.
• Now attach the base of the previously prepared new product to the tetrahedral pin.
• Next, seal the connections using the washer that you removed when dismantling the previous wiper.
• Finally, screw in the housing mounting bolt.

Mount "MBTL1.1"

This type of mount was introduced in 2013. Called according to Bosch markings - MBTL1.1 or GWB045, used in new Mercedes-Benz models. Buy brushes with MBTL1.1 mount. Learn more about the “MBTL1.1” mount and video installation instructions.

conclusions

So, why do you need to replace your windshield wiper blades? Toyota or any other car model needs this procedure regularly. Such actions can reduce the risk of traffic accidents in bad weather. Experts recommend replacing them once a year or immediately after you notice that the wipers have begun to perform their duties poorly.

Changing windshield wiper blades for the front and rear windows is very simple. In the first case, you just need to follow the general instructions. And in the second, take into account the individual characteristics of your “iron friend”. It will be a little more difficult to cope with frameless products, but nothing is impossible here. A little patience, effort and caution - and you will quickly complete the task. Change your wipers regularly and you will be able to fully enjoy driving your car in any weather conditions.

Replacing windshield wiper blades is a question that will sooner or later arise before every driver. Find out how to remove windshield wiper blades, how to replace them and prevent breakdowns in the article below.

How to remove wipers completely

To conveniently dismantle the cleaners, you will need access to the engine compartment. Open the lid - now you can see the entire wiper lever. It is attached using a bolt connection. As a rule, during operation, moisture and dirt accumulate in this place, so the nut and bolt may become sour. To facilitate dismantling, use WD-40 (read about how to make WD 40 with your own hands).

When the nut comes off, unscrew it. Now you need to pull the lever off the bolt. This is very difficult: you need to additionally use a key to pry the holder off from all sides. The repairman must not overdo it and break the holder rod.

We recommend that you maintain regular windshield wiper maintenance and use high-quality components to ensure driving safety.

A car is an expensive pleasure. And this is not at all connected with its market value, but with the need to periodically replace all consumables and parts. This even applies to windshield wipers, or wipers, as we used to call them. After all, the constant interaction of windshield wiper blades with dust, dirt and water leads to their wear. And in a worn-out state, they are as useless as milk from a goat. Well, driving a car with dirty windows is the same as driving with your eyes closed.

So car owners have to go to a special store and buy wiper blades. Fortunately, at least their replacement can be done without outside help and expensive professionals. So today we decided to help you in a similar situation and tell you how to replace the rear wiper blade.

We study the causes of rear wiper blade wear

If a car is used regularly and under a variety of weather conditions, as well as on sections of the road of varying complexity and pollution, over time even its main “organ” - the engine - wears out. Therefore, wear of the rear windshield wiper blade should not surprise you, especially since they always have to interact with external conditions. What role do windshield wipers play on a car?

The immediate task of these devices is to provide a good view of the space in front and behind the vehicle. In turn, this factor is directly related to road safety. So the windshield wipers, just like the seat belt, are the most important elements of the car that save the life of the driver.

Why do we turn to the rear windshield wiper and not the front ones? If you are an experienced car owner, you have probably noted more than once that it is the rear wiper blade that wears out faster, which is why it has to be replaced more often. And since the rear and front windshield wiper blades are attached almost identically, a description of the process of replacing one will help you successfully cope with replacing the other.

A variety of reasons can lead to wear of the described parts. This is mainly due to the aerodynamic features of the car. While driving, the wind blows dust and dirt off the windshield. Even raindrops can fly off of it on their own. At the same time, all this is carried back and settles on the rear window. Also, dust constantly flies here from under the wheels of the car, and particles of fuel and lubricants from the exhaust pipe settle. So it turns out that the rear wiper has to work two or even three times more intensely than its front brothers. And the driver is forced to change the rear windshield wiper blades from time to time.

Design features of automobile windshield wipers and their blades

In order to be able to easily deal with rear wiper blades, it is undoubtedly necessary to understand the features of their design. To do this, we will look at examples of the most common windshield wiper blades. Their main details are:

1. Assembly for attaching brushes to wiring. This part on almost all modern brushes is made removable. Thanks to this, the fastening unit is almost universal. Compatibility with fastenings of various types of leashes is ensured thanks to a special adapter that fits onto a pin at the base of the brush. Different manufacturers produce different forms of adapters. By the way, the reliability of the connection depends on the shape of the adapter.

2. Rocker arm pressure block (pressure system). The most classic version of the pressure block is a system of rocker arms articulated with each other. The number of these rocker arms may vary slightly, but usually they are presented in a set of no less than three and no more than six pieces. This number directly depends on the length installed on the brush holder, and most often amounts to five.

When do brushes need to be replaced?

Everyone knows what “wipers” are - this is a special device in the form of a lever and a brush for cleaning the windshield and sometimes the rear window. They can be framed or frameless. In the first option, these are moving parts that hold the cleaning surface on the wind window.

Glass cleaning mechanism

Unfortunately, this species is quite delicate because it is vulnerable to snow and rain, which eventually turns into ice and damages the frame surface. In addition, the cleaning part does not fit tightly to the surface, and therefore does not clean well enough.

Useful tips

As you can see, the issue of replacing wipers is not as simple as it might seem at first glance. It is important to choose the right solution based on the type of fastening, as well as the size. By the way, size also plays an important role.

You can often see in catalogs that wipers of different sizes (both longer and shorter) can be installed on a particular car. So, it is necessary to take into account the fact that brushes can be framed or frameless. Each option has both its pros and cons. At the same time, frame wipers look more modern and are widely in demand today.

However, you should not settle for the largest length option from the permissible sizes in the catalog, since in practice it is often not possible to achieve a tight fit of the blade to the glass along the entire length. The result is that there are omissions, squeaks may appear during operation, such brushes rub worse at the edges, etc.

Let us also add that sometimes replacing wipers even with the highest quality new products does not produce results. This happens when there are defects in the wiper arms (leads) or the windshield itself has defects and scratches. If in the first case the problem can be solved by adjustments, replacing springs or the entire lever, then in the second you need to work with glass.

We also recommend reading the article on how to polish a car windshield. From this article you will learn when and why you need to polish your windshield, in which cases polishing your windshield is the right solution, and how to properly polish your windshield yourself.

Scratches inevitably appear during operation and can be quite deep if the wipers often work “dry” and fine abrasive, sand, etc. actively gets on the glass. Also, in the case of replacing the windshield, a solution may not be of the highest quality.

In turn, individually or in combination, these factors lead to the fact that the wipers cannot properly remove dirt from the surface, and streaks remain. The solution in this situation is professional polishing of the windshield or its complete replacement with a high-quality analogue.

Only in this case, installing new wipers or replacing brushes will allow you to get the best result. If the glass is defective, then no wipers can completely correct the situation.

Instructions for removing and replacing wipers

It is very easy to replace used material, and you can do it yourself. The only thing that is important to do is to buy a new part that is the same size as the old one. After all, wipers often differ in length from each other and this is also important to take into account.

Dismantling occurs in stages:

1. The lever is placed vertically and removed from the windshield. It is important to hold it carefully so as not to injure it. If it pops out, it may damage the glass.
2. Now you need to open the holder cap and pull the brush down, while holding the holder firmly.
3. After this, you need to take the previously stored part, put it on the knitting needle and close the cap. Now pull it down, leveling it out. Thus, the operation is completed and you can proceed with another window cleaner. It is filmed in exactly the same way (the author of the video is TheBrandConnect).

Features of replacing rear wipers

There are some car models on which it would also be a good idea to install rear window wipers. The installation pattern on the rear windows is quite different from the installation of the glass cleaner on the front windows. In the case of installing rear wipers, it is impossible to say how to change the wipers, because all cars are different and the approach to them is individual. As an example, we can take the usual Lada Kalina station wagon.

1. There is a fastening nut on the wiper, and above it there is a protective element. This metal cap must be lifted up.
2. Then take a 10mm wrench and, carefully, so as not to drop the washer under it, unscrew the nut. Now turn the device a little and carefully pull it towards you. It will come off without any problems. After this, you can remove the mechanism to clean the windows.
3. Now, on the dismantled device, you need to pull the part and use a screwdriver to loosen the latch that holds the part to the lever. You can replace it in the same way as replacing front windshield wipers. When buying brushes, you need to pay attention to the bend of the brush, because even this affects the quality of cleaning.

Varieties of design

Malfunctions of car wipers and how to fix them

The main prevention of car wipers is to inspect the entire structure for dirt and the presence of foreign bodies, such as pieces of ice, dried dirt, and so on. If such elements are identified, they should be removed immediately.

The appearance of stripes after a wiper passes the area. If this effect occurs, the entire system should be checked for any foreign objects that may be preventing the wiper blade from being in the correct operating position. Dirt may get into the joints of the rocker arms, preventing them from functioning fully, or dirt may appear in the grooves with which the rubber strip is attached to the wiper. The second option is possible and common in the cold winter, when, before the start of a trip, vehicle owners manually tear off the frozen wiper system from the windshield of the car. In this case, very often the rubber band comes out of the grooves due to the use of physical force. The working element of the wiper loses its working position and fails to cope with its duties.

Gradual expansion of the non-cleanable strip

If a stripe appears on the car glass when connecting the windshield wiper, which is not cleaned when the car wipers operate and which, over time, becomes larger and larger, you should pay attention to the wear of the working surface of the system. Rubber tape, unfortunately, has its own service life, which depends on many factors: frequency of use, weather conditions, ecology at the place of use, and so on.

Over time, small cracks appear on the working surface of the wiper, which gradually increase and do not allow the device to fully cope with its duties. Damaged or jammed connections between the rocker arms can prevent the rubber band from moving into position when changing direction - this can also cause streaks on the car window.

Another reason for the ineffectiveness of car wipers is the gradual rounding of the working surface of the system due to its long-term use. The working surface is no longer rectangular, which means it can’t do its job. If it is discovered that the wipers do not work, after trying to turn them on, it requires an inspection of the entire system - for example, something may be interfering with their movement. If a visual inspection does not yield anything and the wipers do not work anyway, then you need to check the connection system with the car and inspect for breaks.
