What is the solution to the abnormal sound of the wipers?

You can refer to the following methods to check the problem.

Open the lead cover to see if the drive link is out of place (this is the most common cause).

Check that the fuse is in good condition.

Disassemble the motor cord plug to turn on the power supply, and use a multimeter to measure whether there is voltage.

If the fuse is intact and the motor has no voltage, check whether the circuit and turn signal combination switch is intact.

Generally, the motor will have a burnt smell when it burns out.

If you turn on the power supply and measure the normal voltage at the wiper motor, you can consider that the motor is broken.

Pay attention to whether the pole is connected to the wiper rocker arm in the correct way. Some of the arms are screwed to the rocker arm, while others are locked with a buckle.

Pull the wiper up and touch it with your finger to check for damage to the cleaned rubber wiper and the elasticity of the rubber blades. If the blades are aged, hardened, or cracked, then the wiper is broken.

During the test, the wiper switch is placed at various speed positions to check whether the wiper maintains a certain speed at different speeds. Especially in the intermittent working state, it is also necessary to pay attention to whether the wiper maintains a certain speed when it is in motion.

Check the wiper status and whether the wiper rod has uneven swing or leakage. If the following three situations occur, it means that the wiper is unqualified: first, the swing is not smooth, and the wiper is not beating normally; Second, the contact surface of the rubber and the glass surface cannot be completely fitted, resulting in wiping residue; Third, after wiping, the glass surface presents a water film state, and fine stripes, fog and linear residues are produced on the glass.

During the test, attention should be paid to whether there is abnormal noise in the motor, especially when the wiper motor is humming and does not rotate. This indicates that the mechanical transmission part of the wiper is rusted or stuck, and the wiper switch should be turned off immediately to prevent the motor from being burned.

Hello landlord!! It is a very common phenomenon for wipers to have abnormal noise, which is not considered a fault, and a car owner can judge the cause and solve the abnormal noise in the following ways. 1.

The wiper blades themselves are a problem. Wiper blades are rubber products, which will be aged and hardened after a period of use, and it is more obvious in winter.

Hello! Glad for your question.

1. Wiper blade aging: two wiper blades are rubber products, which will be aged and hardened after a period of time, and it is more significant in winter. Most wiper blades are recommended to be replaced every one to two years.

2. There is a foreign object in the middle of the wiper blade: when the wiper is opened, there will be a sharp sound of friction between the wiper blade and the front windshield.

3. The installation angle of the two wiper arms is wrong: it will affect the wiper blades to jump on the windshield, then it will cause a sound. If the two wiper blades are normal, you need to adjust the angle of the wiper arm so that the two wiper blades are perpendicular to the windshield plane.

Abnormal sound of upper scraping, counterclockwise rotation adjustment, pay attention to protect the wiper blade when adjusting. Rotate clockwise to adjust, and pay attention to protect the wiper blades when adjusting. When the wiper blade and the windshield are mixed with foreign objects caused by abnormal noise, when the wiper blade is turned on, there will be a sharp noise of friction between the wiper blade and the front windshield, and the owner can check the cleaning of the old base wiper or the foreign object under the wiper to ensure that the wiper blade is clean.

The angle of the wiper rocker arm is unreasonable, which can easily lead to excessive friction between the wiper strip and the glass, or the knife edge of the strip is not perpendicular to the glass surface. When used, it is easy to shake and deform the wiper strip, resulting in abnormal noise. The swingarm angle can be adjusted with pliers so that the wiper strip is as perpendicular to the glass surface as possible.

If necessary, you can go to the 4S store to accurately measure the angle of the rocker arm.

Precautions for summer use:

Exposure: When the vehicle is exposed to the scorching sun in summer, the temperature of the glass surface will rise to more than 60 °C, and the wiper strip is pressed on the glass for a long time, and the rubber strip is easy to deform and aging at high temperature, which greatly reduces the service life of the wiper blade, therefore, it is recommended to park the vehicle in a cool place as much as possible in summer, which can not only delay the aging of the wiper blade rubber strip, but also reduce the damage of high temperature and ultraviolet rays to the car paint.

High-speed driving: I believe that many friends have had such an experience, there are many mosquitoes in summer, there will be a lot of mosquito corpses on the front windshield after running at high speed, due to high-speed driving mosquito corpses are quickly dried and hardened, at this time, if you use a wiper to clean up the insect corpse, not only can not clean up but also the wiper strip will be cut and damaged.

In addition to the aging of the adhesive strip itself or the wiper arm has problems, most of them are the problem of glass oil film, try the dish soap directly at home, spray foam and set it up for a few minutes, and then wipe it with a hand towel or a bath towel.

Wipers know the tips for solving the abnormal noise of the stove: 1. The wiper blade abnormal noise caused by the wiper itself, the wiper is a rubber product, and it will be aged and hardened after a period of use, and it is more obvious in winter, if it has not reached the cleaning effect, the most simple and effective solution is to directly replace the new wiper piece. Generally, wiper blades are recommended to be replaced for one year or one year; 2. The foreign object between the wiper blade and the windshield produces abnormal sound, when the wiper is started, there will be a sharp friction noise between the wiper blade and the front windshield, and the owner can be erected to check the cleaning of the wiper or the foreign body under the wiper to ensure the cleaning effect of the wiper blade; 3. The sound of wiper rod rubbing against the bushing, the wiper connecting rod of the long age will age, the elasticity of the wiper arm spring will decrease, and the bushing will wear out or even fall off.

Please check the wiper arm or wiper connecting rod bushing; 4. The abnormal sound emitted by the wiper motor, if the wiper motor itself emits an abnormal sound, 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 repair shop for a more detailed inspection.

Pacific Automobile Network] The wiper blade itself asks a hail question, causing the wiper blade to make an abnormal sound. Wiper blades are rubber products, which will be aged and hardened after a period of use, and are more obvious in winter. Generally, it is recommended to replace the wiper blade once every one to two years.

Abnormal noise caused by foreign objects between the wiper blades and the windshield. When the wiper is turned on, there will be a sharp sound of the wiper blade and the front windshield rubbing, and the owner can check and clean up the foreign objects under the wiper blade or wiper to ensure that the wiper blade is clean.

The sound of wiper connecting rod bushings rubbing. After a long time, the wiper linkage mechanism will age, the elasticity of the wiper arm spring will decrease, and the bushing will wear out or even fall off. Please check the wiper arm or wiper link bushing.

The abnormal sound of the wiper motor. If the wiper motor itself makes abnormal noise, it is very prudent to judge the performance before the end of the life of the motor, and it is recommended to go to a professional maintenance shop for a more detailed inspection.

The car wiper has an abnormal noise when it is in use, and the rain on the windshield cannot be washed. In this case, first check your car's wiper strip for something like sand or leaves. If there is no foreign object on the wiper blade of the car, but there is an abnormal noise when using the wiper, the solution is to gently sand the wiper blade with sandpaper.

Apply soap and jujube soap on the wiper blade, if it can't be solved, there is still abnormal noise and unclean scraping when using the car wiper blade, you can only replace the wiper rubber strip with a new one.

A car's wiper blade is the most vulnerable to damage because it won't be a hassle to replace it. Moreover, after exposure to the sun and rain, the wiper blade is easy to age and damage.

Replacement is recommended

When using a car wiper, there will be an abnormal noise, and the rain and dust on the front windshield of the car cannot be cleaned. The service life of car wiper blades is generally half a year to one year, and it is recommended to replace car wiper blades as long as they are used for more than half a year. If the wiper of the car breaks down on a rainy and foggy day, it is dangerous to drive on the celery.

Therefore, the wiper blade is also one of the more important parts of the car.

The wiper itself is a wear part, and its structure mainly includes an elastic structure and a rubber wiper strip. The old-fashioned boneless wipers have only one support arm in the middle, and then two sets of four-point jibs are connected at both ends. After the connection position is fixed with the wiper arm of the vehicle, the wiper arm spring is used to apply pressure.

Pressure distribution from one point to four points can cause uneven pressure, and long wiper strips will have high pressure near the fulcrum and low pressure elsewhere. Then the wiper strip will be cleaned in different areas, different strengths, and the effect of drainage will naturally be different.
