What causes the wiper glass squeak?

Indicates that the wiper holder is twisted upwardsLet the wiper stop in the middle position (pull the wiper control handle towards the steering wheel after the car is turned off), then gently pull it up, wrap the steel frame with a cloth or soft thing, use a wrench or pliers to grip the wrapped part and twist it down a few times, and try to scrape after resetting, the abnormal noise will be much smaller.

If so, repeat again until the squeak is eliminated. If it turns downward, you need to twist in the opposite direction until the squeak is eliminated.

Precautions for the use of wipers.

1. Hatchbacks, SUVs, MPVs and other models need to be equipped with rear wipers, and the rear windshield should be cleaned at any time to ensure a clear view of the rear.

2. The switch of the rear wiper is also set on the wiper lever, which is two independent systems with the front wiper mechanism and can be controlled separately. There are two styles of rear wiper switches, which are toggle type and knob type.

The reasons why the wiper squeaks the glass are as follows:

1. The wiper squeaks when going up: it means that the wiper holder is twisted upward, and if it becomes downward, then it needs to be twisted in the opposite direction until the abnormal noise is eliminated.

2. The wiper blade itself is a problem: it will age and harden after using it for a period of time, and the easiest and most effective way is to replace the wiper blade with a new one.

3. There are foreign objects between the windshield of the wiper blade box: the sharp sound of friction between the wiper blade and the front windshield, the owner can check and clean up the foreign objects under the wiper blade or wiper to ensure that the wiper blade is clean.

Note. 1. Pay attention to the length of the wipers on the side of the driver and the co-driver, the width and connection of the joint buckle between the wiper blade and the wiper arm, and the connection method is also different, and pay attention to distinguishing the vehicle.

2. It is recommended to prepare a rag to thickly wrap the elbow of the wiper arm before removing the old wiper blade, and then gently place it on the windshield, which is to prevent the wiper from starting by mistake and scratching the windshield.

3. The wipers of some models are hidden, and it should be noted that the "maintenance mode" of the wiper needs to be turned on before it can be replaced normally.

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.

Wiper glass squeak could be:

1. There are miscellaneous foreign objects in the grooves on both sides of the wiper skin.

2. The car glass is dirty.

3. The wipers are deformed and aged. You can first check whether there is a foreign object between the wiper strip and the glass, and then check whether the rubber strip part of the wiper strip has hardening, notching, tearing or tearing, if there is, you need to replace the wiper blade.

Solution: When the wiper is dry, move the wiper to the maintenance position, lift the problematic wiper, and twist the wiper skin to the left and right several times, which can generally squeeze out the sand particles in the trench.

If it doesn't work, or if the wipers are wet, use a small flathead screwdriver to cut along the grooves on both sides of the wiper skin from head to tail. Or because there is a loose strip clamp on the wiper, use needle-nose pliers to clamp the gap between the joints and the rubber sheet.

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.

It should be that the wiper blade is worn, the surface is uneven and causes the glass to squeak, or it is possible that the wiper is not good, if you are not very good at maintenance, you can go to the auto repair shop to check it.

Hello! Replace the wiper blades as soon as possible. The wiper blades are made of plastic, and after a long time, the rubber will be hard, so it will sound when scraping the glass. You can buy the same size wiper blades and replace them yourself. You can also go to a car detailing repair shop for a replacement. Hope to adopt, thank you!

Wipers exposed to the wind and sun for a long time will cause the rubber to deteriorate, and there will be a sound when used.

The reasons for the squeak of the wiper glass are: 1. The front windshield is easy to accumulate dust if it is not cleaned for a long time, and the surface becomes rough, and the wiper not only does not scrape clean in the process of scraping, but also causes scratches on the glass; 2. The car experiences wind and rain, and the dust in the air falls into the wiper grinding document, and the wiper with sand particles is used to scrape the water, which is equivalent to scraping the rubber strip with a grinding wheel. Windshield wipers are a simple tool for cleaning the front glass of a motor vehicle to prevent blind wheels, rainwater and other dirt from affecting the vision.

The reasons for the squeak of the wiper glass are: 1. The wiper squeaks when going up: it means that the wiper holder is twisted upward, and if it becomes downward, then it needs to be twisted in the opposite direction until the abnormal noise is eliminated.

2. The wiper blade comes with its own body: it will age and harden after using it for a period of time, and the easiest and most effective way is to replace the wiper blade with a new one. 3. There are foreign objects between the windshield of the wiper blade box

The sharp sound of friction between the wiper blade and the front windshield, the owner can check and clean the wiper blade or the foreign object under the wiper to imitate the front belt to ensure that the wiper blade is clean. 4. Linkage mechanism: The deformation of this mechanism or the influence of the motor, gap relay, etc. 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.

5. The angle between the wiper and the wiper arm is incorrect, causing the wiper blade to jump on the windshield, resulting in abnormal noise.

The reasons for the abnormal noise of wiper wipers are explained as follows:

1. The wiper blade is aging.

Wiper blades are rubber products, which will age and harden after a period of use, and are more obvious in winter. Generally, it is recommended to replace the wiper blades once to every two years.

2. There is a foreign body in the middle of the wiper blade.

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 the foreign objects on the wiper blade or under the wiper to ensure that the wiper blade is clean.

3. The installation angle of the wiper arm is wrong.

Causes the wiper blades to jump on the windshield, causing an abnormal noise. If the wiper blades are normal, you need to adjust the angle of the wiper arm, and the wiper blades should be perpendicular to the windshield plane. You can find pliers to get it yourself, 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 linkage mechanism is deformed.

The deformation of this mechanism or the influence of the motor, gap relay, etc., may lead to abnormal noise, as well as due to the use of too long, 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.

About the introduction of wipers

1. Generally, there are vacuum wipers, electric wipers and wipers with electronic control units.

2. The disadvantage of the vacuum wiper is that the speed of the wiper is unstable. When the engine vacuum level is reduced, such as when climbing a mountain, the wiper blades stop oscillating, blurring the driver's vision.

3. The electric wiper is driven by a motor. Generally, it is composed of wiper arm, wiper blade assembly, rubber brush blade, brush bracket, wiper arm shaft, wiper bottom plate, motor, Paizheng deceleration mechanism, drive connecting rod, drive rod hinge, wiper switch, wiper switch knob, etc.

The causes and solutions of the abnormal sound of the wiper scraping glass are as follows: 1. Aging of wiper blades: Wiper blades are rubber products, which will age and harden after a period of use, and it is more obvious in winter.

Solution: Replace the wiper blade with a new one, generally the wiper blade is recommended to be replaced once every one to two years. 2. There is a foreign body in the middle of the wiper blade.

When the wipers are turned on, there is a sharp sound of the wiper blades rubbing against the front windshield glass. Solution: Clean the wiper blades or foreign objects under the wiper blades to ensure that the wiper blades are clean.

3. The installation angle of the wiper arm is wrong: the wiper is missing and the plum piece jumps on the windshield, which causes abnormal noise. Workaround:

Adjust the angle of the wiper arm. 4. Deformation of the linkage mechanism: the deformation of the mechanism or due to the delay of the motor, the deformation of the gap relay or its own mechanism, the hairpin, the rust, etc.

Solution: It is recommended to clean the glass with cleaning solution or replace it with new wiper blades.
