Help, my wiper scrapes the glass very loudly, what can be done

It is the friction between the wiper blades and the glass, etc.

Hello, this one suggests that you replace the wiper blades on it.

Hello, is the wiper ringing or the wiper scraping the glass is the glass ringing?

Causes and solutions of abnormal noise of automobile wipers:

1. The wiper itself is caused by abnormal wipers, the wipers are rubber products, aging and hardening will occur after a period of use, and it is more obvious in winter, if it has not been clean, the most simple and effective solution is to directly replace the new wipers, and the general wipers are recommended to be replaced once every one to two years;

2. The noise caused by foreign objects between the wiper and the windshield, when the wiper blade rotates, there will be a sharp sound of friction between the wiper and the front windshield, and the owner can check and clean the foreign object under the wiper or the windshield to ensure that the wiper is partially clean;

3. The sound of friction of the wiper connecting rod bushing, the wiper connecting rod mechanism will be aging after a long time, the elasticity of the wiper arm spring will decrease, and the bushing will also wear out, or even fall off, you need to check the wiper arm or wiper connecting rod bushing.

It is estimated that the wiper sheet rubber strip is aging and stiff and inelastic, so gently polish it once or twice with fine sand paper, and if it is still loud, it is recommended to change the boneless wiper sheet.

The wipers are supposed to clean up the rain and dust attached to the front windshield to avoid affecting the driver's vision and improve the safety of driving. If the wiper keeps ringing when scraping the glass, it will affect the driver's attention while driving the vehicle.

Why does the wiper scrape the glass keep ringing:

1. The wiper arm is deformed, and when in use, the wiper arm will sound when it hits the glass;

2. The oil film on the front windshield has not been removed, resulting in abnormal noise and shaking when the wiper scrapes the glass;

3. The wiper brush has been used for a long time, and it has been aging and deformed;

4. There are sand, stones and other hard substances between the front windshield and the wipers.

How to deal with the rattling sound on the wiper glass:

1. Check whether the wiper arm is in contact with the front windshield, if it is in contact, it is said that the stool disturbs the wiper arm and there is a deformation phenomenon, and you can use a wrench to adjust the wiper arm;

2. Wash the water on the surface of the front windshield for testing, if the water does not condense on it, then it means that the front windshield has an oil film, and you can use the principle that hydrochloric acid and zinc powder will react with silicon elements to polish the glass, and then wipe it, and finally the front windshield must be cleaned;

3. Clean the front windshield glass and jujube glass, mainly to clean up the sand, stones and other hard substances;

4. If the rubber strip of the wiper brush is hardened and notched, it is necessary to replace the wiper brush in time.

Precautions for wipers:

1. Do not use the wiper in the absence of glass water, which will damage the wiper rubber strip to cause hail and filial piety;

2. If there are hard things on the front windshield, such as bird droppings and stones, remove these things by hand first, and then use the wiper adhesive strip to clean them;

3. Be sure to use special glass water, do not add water and dish soap to use as glass water, which will affect the cleaning effect.

The new car's wiper excites the glass scraping sound several times, which may be caused by the following reasons:

1.The glass does not have a water Ming Zheng stagnation. When scraping the glass with a wiper, be sure to spray the glass water before scraping, and don't scrape it dry, which will not only cause friction, but also scratch the glass.

2.Wiper belts are acute. Generally, when the hair of the wiper blade is dry or hardened, there will be friction noise.

3.The glass is too dirty. When the windshield has gravel or thick dust, there will be friction noise.

4.The wiper strips are uneven. It may be incorrectly installed or severely bent, resulting in incomplete, uneven contact with the glass.

Generally, the life of the wiper blade of the car will harden in about 2-3 years. Wiper blades are also consumables for dry cars. Wiper blades are rubber products that will age and harden after a period of use, especially in winter. Millions of car purchase subsidies.

Hello dear. The solution to the loud scraping of the glass of the automobile wiper is as follows: 1. The wiper blade can be replaced directly, and at the same time, a part of the special washing liquid can can be added to the watering can in the car to increase lubrication and eliminate noise.

3. If there is a lack of cleaning, through development and change, a layer of mixed oil film that is extremely difficult to clean will be formed on the surface. You can clean the glass with a cleaning solution to see if it works. Replacing the wipers can solve the noise problem when scraping the glass.

3. If there is still noise, it is likely that there is a problem with the motor. For example, if the external line voltage is insufficient or there is a problem with the adjustment part of the relay, it will basically affect the abnormal working state or sound. Attached Introduction:

The so-called wiper is a tool for simple cleaning of the front glass of a motor vehicle in order to avoid rain and other dirt affecting the line of sight.

Car wipers scrape glass very loudly Solution:

If the wiper blade itself is causing the wiper blade to make an abnormal noise, the simplest and most effective solution is to directly replace the wiper blade with a new one. Generally, the wiper blade is recommended to be replaced once every one to two years, if it is an abnormal sound caused by foreign objects between the wiper blade and the windshield, check and clean the foreign body on the wiper blade or the bottom of the wiper to ensure that the wiper blade is clean.

Other workarounds:

1. The sound of friction of the wiper connecting rod bushing: the wiper connecting rod mechanism will age after a long time, the elasticity of the wiper arm spring will decrease, and the bushing will also wear out and even fall off. Please check the wiper arm or wiper link bushing.

2. The abnormal sound emitted by the wiper motor: If the wiper motor itself emits abnormal noise, it is likely to be the performance of the motor before the end of its life, and it is recommended to go to a professional maintenance plant for a more detailed inspection.

3. In most cases, the angle of the wiper arm is not the same as that of the wiper arm, resulting in the wiper blade jumping on the windshield, resulting in abnormal noise. If the wiper blades are normal, you need to adjust the angle of the wiper arm so that the wiper blades are perpendicular to the windshield plane.

You can find pliers, put a rag on the head of the wiper arm, and then pinch it with pliers, break it hard, and try to make the wiper blade perpendicular to the windshield plane.

4. The deformation of the linkage mechanism or the influence of the motor, gap relay and other influences (such as too fast or too slow or non-stop action) may lead to abnormal noise, as well as due to the use of too long time, the deformation of its own mechanism, hairpin, rust and abnormal action, etc.

If it is a new wiper blade, it is recommended to check whether there is dirt or oil stains on the top of the glass, and it is recommended to clean the glass with cleaning solution or change the new set to try it. If there is still an abnormal noise, use a tool such as pliers to adjust the wiper arm angle. However, it is recommended to go to a repair shop for special tools to adjust.

The car wiper scrapes the glass very loudly, and you can solve it yourself.

The first reason why the wiper has a croaking sound is that it is mixed with foreign objects, such as small sand particles or leaves and branches, etc., the solution at this time is very simple, lift the wiper blades carefully, and gently wipe the wiper blades with your fingers from beginning to end to remove foreign objects.

The second reason for the croaking is the aging of the wiper blade, the wiper blade is a rubber product, the aging speed is very fast, it needs to be replaced in three or four years at most, and the replacement is very simple, according to the model to buy the appropriate length of the wiper blade can be replaced, and the two wiper blades can be replaced in a maximum of 5 minutes.

The third reason is that the connecting rod of the wiper has a quality problem, resulting in the wiper blade tilting or the connecting rod is loose and cannot work normally, so in this case, don't do it yourself, it is best to go to the repair shop to replace a brand new wiper on it.
