What causes car wiper failure?

Introduction: With the improvement of people's economic level, every household has a private car, as an indispensable means of travel for every family, it brings great convenience to people's daily travel, especially when it rains, it can be protected from rain. It has increased people's travel comfort, and at the same time, the functionality of the car has become more and more perfect.

1. Wipers.

The wiper of the car is an extremely important part of the car, which gives a lot of convenience to many car owners when it rains, and the wiper can be opened to clean some dirt on the glass of the car, and at the same time, it can also be cleaned with glass water in the weather when it is not raining. Wiper compound is mainly composed of a fixed lever and a wiper lever. Electric wipers are used in ordinary cars, which are simple in structure and easy to operate, while wipers were invented by the Germans in the 19th century at the earliest.

Second, the cause of the failure.

When using the wipers, if you hear an unusual sound, especially a sound, but the wipers are not working, it means that there may be rust or stuck. At this time, it should be turned off in time, if he doesn't work because there is no sound, it may be because the fuse is burned. When it rains lightly, the wipers cannot be cleaned thoroughly, and the windshield will leave marks on the glass.

In daily use, if you find that the wiper is not working, you must go to the 4S shop for repair in time. <>

3. Purchase. There are many ways to replace the wiper, first of all, you need to borrow the rotation ability of the motor to let him work, if you find that there is hardening or damage to the wiper, you must buy a new product in time. In daily life, the wipers should also be maintained, not only to clean the surface of the body, these small parts should also be cleaned in time, plus the northern cities are generally dusty, so the wipers should be cleaned in time, to avoid high temperature exposure, and use more protective agents to protect.

The failure of the wiper may be caused by these four points: 1. The wiper insurance fuse, the user can replace it by himself, ** the fuse box sticker, find the number of insurance, pull out the old insurance and replace it with the prescribed fuse current flow insurance; 2. The wiper switch is damaged; 3. The wire plug is loose or has poor contact due to rust; 4. The wiper motor is damaged or the motor is poorly grounded; 5. Connecting rod mechanism, turn.

1. It is possible that the wiper fuse is blown out.

2. If the wiper does not move, it may be that the electrical machine is burned.

3. Or the wiper switch is broken. The wiper may not move because the fuse is broken, so the wiper can't move, so you have to open it to take a look, if so, just replace it.

If a car's windshield wipers fail, it is usually a problem with the sensor, but it is also possible that the wipers are malfunctioning.

It is possible that the wipers of the car are out of order because the wipers are broken, or there is a problem with the wipers of the wipers.

It could be because the system is malfunctioning, or it may be due to a short circuit, or it may be broken with the wipers.

The switch circuit is not good, or the motor is broken, or it is used for too long and there is a problem.

1. In most cases, the angle of the wiper arm is not the same, resulting in the wiper blade jumping on the windshield, resulting in abnormal noise.

Solution: 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.

2. The wiper blade itself is a problem.

Solution: Wiper blades are rubber products, use for a period of time, aging, hardening, winter is more obvious, if it has not been clean, the easiest and most effective way is to replace the new wiper blades. Generally, it is recommended to replace the wiper blades once to every two years.

3. There are foreign objects between the windshield of the wiper blade box.

Solution: When the wiper is turned on, there will be a sharp sound of the wiper blade and the front windshield rubbing, the owner can check and clean the wiper blade or the foreign object under the wiper to ensure that the wiper blade is clean.

4. Linkage mechanism.

The deformation of this mechanism or due to the influence of motors, gap relays, etc. (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, the deformation of its own mechanism, hairpin, rust and abnormal action, etc.

Solution: If it is a new wiper blade, it is recommended to check whether there is dirt or oil stains on the glass, and it is recommended to clean the glass with cleaning solution or change a 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.

5. The scraping is not clean, and there is abnormal noise.

Solution: Explain that the wiper holder is twisted upward, let 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 clamp the wrapped part and twist it down a few times, scrape it after resetting, the abnormal noise will be much smaller, if so, repeat it once until the abnormal noise is eliminated. If it turns downward, you need to twist in the opposite direction until the squeak is eliminated!

Possible causes: Damaged wiper motor; The wiper fuse is broken; Wiper motor line break; The wiper relay is damaged. The power source of the wiper comes from the electric motor, which is the core of the entire wiper system.

The quality requirements of the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor mounted on the front windshield is generally made with the worm gear mechanical part.

The reasons why the wiper of the car does not work are: 1. The fuse is broken; 2. The motor burns out; 3. There is a fault in the place where the wiper connecting rod is connected; 4. The wiper switch is faulty; 5. The wiper line is faulty. Wipers are also known as wipers, water picks, wipers, or windshield wipers, and their functions are:

Brush to remove rain and dust attached to the windshield of the vehicle to improve the visibility of the driver and increase driving safety. The maintenance methods of the wiper are: 1. Clean the wiper regularly; 2. Regularly check whether the wiper can work normally; 3. Don't scrape hard when there is something on the glass; 4. Use slow speed scraping; 5. The wipers should be erected when parking in the open air under the scorching sun; 6. Use special car cleaner.

With the continuous development of the times, the application of cars in our daily life has become more and more, and because of this, there are many people who are very familiar with the driving of cars, and when driving a car, if there is a failure of the wipers, then it is relatively dangerous in rainy weather, so in the face of this situation, how should we deal with it?

Through the above understanding, we can know very clearly that after the wiper has a problem, most of the cases need to be replaced, and the ** wiper is relatively cheap, so after finding that your wiper cannot work normally, you must replace it in time, do not continue to use the factors that do not have much impact, if you continue to use it, then it will also have a certain threat to our safety.

It is advisable to drive the car to an auto repair shop and then have a professional change a pair of wipers.

Fault 1: Fine streaks, fog and linear residues on the glass.

Causes: Attachment of foreign bodies, sand, dust or damage to the triangular tip of the triangular edge.

Solution: Clean the sharp edge or replace the wiper blades.

It can be cleaned, or it can be replaced with a wiper, and you can also check some small accessories, etc., so that you can dispose of it.

The main reasons for the failure of the automobile wiper are as follows: 1. The fuse is burned: the wire is loose or the contact is poor; The wiper control switch is damaged or in poor contact; Armature winding break or reducer.

2. The voltage is too low or the switch contact is poor: the contact surface between the scraper blade and the glass is dirty; Poor lubrication of motor bearings and reducer gears; Caused by poor brush contact or too soft springs. 3. The scraper cannot be reset by itself

That is, the wiper motor can not stop in the automatic stop position, most of which is caused by the damage of the probing switch, the poor operation of the electric peach automatic reset or the broken connection wire.

1. It may be that the connector of the motor is not connected properly, and the lower line needs to be reconnected before it can be used.

2. Turn the wiper to the largest gear and gently dial it with your hand to see if it can rotate, if it can rotate, it can be rusted on the induction of the wiper, and you can clean it directly. Nuclear trouble.

3. Check whether the safety of the wiper is intact and whether the fuse is burned out, and then check whether the electric reform hood machine is burned out, whether the connecting rod is slipped, or whether the combination switch is in poor contact.

Wiper malfunction, may be related to wiper strips, wipers, wiper arms. First of allSee if the wiper strip is broken, the condition of the rubber strip of the wiper is directly related to the working effect of the wiper. If the rubber edge on the wiper blade breaks, the wiper cannot make proper contact with the windshield, removing water droplets or debris.

In the small gaps left by the damaged part of the tape, dust may be hidden, which can scratch or damage the windshield.

Or there may be ice and snow on the windshield wipers, the windshield wipers can remove a small amount of snow from the windshield, but heavy snow needs to be removed with a snow wiper before operating the wipers. Melted snow has a relatively large weight and can bend your wipers. The wiper may bend at the axis of rotation, causing damage to the wiper motor or transmission.

Remove the snow from your windshield before using your wiper blades, and if you live in a place where it snows heavily, such as Northeast China, you may need to buy winter wipers.

If the wiper system is working abnormally only in intermittent gears, first check that the intermittent relay is well grounded. If the ground is normal, check the circuit between the relay and the wiper switch with an ohmmeter. If the wiring is also good, replace the intermittent relay and check the wiper blades regularly.

When it is found that the wiper blade is seriously worn or dirty, it should be replaced or cleaned in time, otherwise it will reduce the working efficiency of the wiper and affect the driver's sight.

The wiper arm is connected to the wiper by a nut on the rotating shaft. The axis of rotation is usually connected by a protruding stud, and the wiper arm is connected by a hole in the base. The nut holds the axle stud firmly in place and the wiper rocker arm securely securely on the axis of rotation.

Normally, if the nut is a little loose, the wiper motor will rotate the fulcrum, but the wiper arm will not move. When the wiper direction changes, you can see it move slightly, but it won't wipe the windshield. If only one wiper works, the other does not move.

If you find this problem, make sure the wiper axle nut is screwed tightly, otherwise you should consider going to a professional repair shop.

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 cable 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 burn out and burn out, and there will be a burnt smell.

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.

This kind of failure is usually the relay of the wiper is broken, and only a new relay needs to be replaced to solve the problem.

This condition is usually caused by a broken wiper fuse and only needs to be replaced with a new one.

<> "Old drivers know that the wiper of the car is a car part that is more prone to failure. So what is the problem with the car wiper not moving?

The fuse of the wiper burned: The electrical equipment of the car will have a fuse to protect its working circuit, and when the current in the circuit is too large, the fuse will be blown to protect the circuit.

The wiper is frozen: in the winter in the north, the weather is relatively cold, when the wiper is frozen, it will also cause the wiper to not move, at this time you need to use warm water to melt the ice on the wiper, otherwise it is easy to cause damage to the motor during use.

Wiper wiper line failure: When the wiper wiper line fails, it will cause the wiper to suddenly move, and you need to find a professional maintenance personnel to check and repair the wiring.

The switch of the wiper is faulty: When the switch of the wiper fails, it will also cause the wiper to suddenly not move, and in this case, not only can the wiper not be started, but also the function of spraying glass water cannot be used, and the switch of the wiper needs to be replaced.
