What are the faults and solutions of car wipers?

Generally, the service life of the wiper is one year. It doesn't matter if it's from a 4S store or bought from outside.

Determine that the wiper is time to change: Clean the glass surface before confirming. Touch the surface of the glass with your hands to make sure that the glass is free of scratches and raised particles. Wipe the wiper strip with a cotton cloth, strictly prohibit vigorous efforts, and confirm whether the strip is scratched, deformed or jagged.

Under normal circumstances, if there is still a waterline or the sound is particularly loud, or it is not clear, you can consider replacing the wipers.

Explanation: Wipers, also known as wipers, water picks, wipers or windshield wipers, are equipment used to brush and scrape away rain and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety. Because of the legal requirements, cars in almost all places carry windshield wipers.

Vehicles such as hatchbacks and minivans are also equipped with wipers in the rear windows. In addition to automobiles, windshield wipers are also installed in other means of transportation, such as trains and trams. Some part of the engineering equipment, I hope thank you.

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.

The car wiper does not move the reason:

1. The problem may be at high speedThere is a pressure plate on the wiper in front of the driver (itself is afterburner for cleaning), due to the high speed of the vehicle, it is under pressure, and the four-link mechanism can not overcome the resistance for the time being, resulting in no action, and it is fine;

2. If it is possible to still move, it means that the motor is goodIt's not a big problem, it's estimated that it's just that the screws are loose or there is something wrong with the transmission, and if you can't get it, go to the repair shop to see;

3. Wipers are also called wiper blades and wiper blades. When the wiper does not move or does not work, it can be dealt with from the following aspects: pay attention to whether the way the strut is connected to the wiper rocker arm is correct.

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 fingers to check if there is any damage on 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.

Car wiper maintenance.

1. Clean regularly.

Car owners should usually develop the habit of cleaning the wipers regularly, and wipe and clean the wipers with a special cleaning liquid every time they wash the car.

2. Check the wiper wiper speed.

Check if the wipers are able to maintain the same amplitude of oscillation at different speeds. If the wiper swings slowly in fast gear, the wiper needs to be corrected.

After using it for a little longer, there will be various small problems with the car wiper, and replacing it is of course the best measure, but we also have to analyze the reasons and know what to do. Generally speaking, the wiper of a vehicle will have the following fault phenomena: Fault 1:

Fine streaks, fog and linear residues are formed 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.

Fault 2: The swing is not smooth, and the wipers are not beating normally.

Reason: The tip of the wiper blade is curved and wavy, and there are other attachments such as wax or oil film on the glass surface.

Solution: Wipe the glass part clean or replace the wiper blades.

Fault 3: The contact surface of the rubber and the glass surface cannot be completely fitted, resulting in wiping residue.

Cause: After a long period of use, the rubber hardens and loses its elasticity or breaks.

Solution: Replace the wiper blades Custer.

Fault 4: After wiping, the glass surface is in a state of water film.

Reason: Deformation of the wiper rod due to rust or external force.

Solution: Replace the wipers.

It may be that the rubber strip is aging, generally when there is no water and dry friction, the resistance is too great, and the wiper motor can not drive the load, which will cause the motor to stall, at this time, the motor stall current is very large, and the motor is easy to burn out for a long time. Of course, the high-end car motor will be overheated and protected, so it will not break so easily. Unless the parts inside are failing.

The structure of the wiper is very simple, mainly a brush and a motor, and there are relatively few failures. Even if the wiper fails to move, most of the time it is because the fuse has been blown out. Just open the fuse box, find the fuse of the wiper, pull it out and replace it, and you can continue to use it.

There are two main types of fuses: chip fuses and glass tube fuses. If the chip fuse blows out, if it is not prepared, and it happens to be driving in the rain, it can be replaced with a fuse on other secondary lines.

If you borrow a fuse for a horn, you can also borrow a fuse for a headlamp during the day. When a glass tube fuse is blown out, it can be replaced with tin foil in the cigarette case in addition to the workarounds described above.

The method is to wrap the tin foil outward on the glass tube a few times to temporarily replace it. The wipers are made of iron wrapped in a rubber sheet and inserted into the end of the rocker arm in an embedded way. Therefore, over time, the wiper blades will fall off, causing the end of the rocker arm to rub directly against the windshield, which will not only not clean the rain, but will scratch the glass.

If the two wiper blades fall down at the same time, if it falls on the left driver's seat, you can remove the wiper blades of the assistant seat on the right, install it on the left side, and then find a rag to wrap the wiper head on the right.

1. The scrape is not clean, and there is an abnormal sound 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), and 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 and try to reset it, 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!

2. The wiper blade itself is a rubber product, which will be aged and hardened after a period of use, and it is more obvious in winter. Generally, it is recommended to replace the wiper blades once to every two years.

3. There is a foreign object between the windshield of the wiper blade box Solution: When the wiper is opened, there will be a sharp sound of friction between the wiper blade and the front windshield, and the owner can check and clean up the foreign object under the wiper blade or wiper to ensure that the wiper blade is clean. 4. The deformation of the linkage mechanism or the influence of the motor, gap relay, 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 time, 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. In most cases, the angle between the wiper blade and the wiper arm is not right, causing the wiper blade to jump on the windshield, resulting in abnormal noise. Workaround:

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 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.

Generally, family car wipers are equipped with standard, fast and slow three gears, which can be adjusted, generally on the right side of the steering wheel. There may be some differences between models.

The manual wiper adjustment method is as follows:

Light rainfall: Don't rush to use wipers when it starts to rain lightly. Spray glass water to moisten the glass before opening it for the first time to avoid dry scraping of the glass window due to lack of moisture.

Heavy rainfall: If the rain is heavy, adjust the working frequency of the wiper in time to ensure a clear vision. If the rain is too heavy and the rain is too urgent, and you still can't see clearly when you drive to the highest gear, it is recommended to find a safe place to stop temporarily and wait for the rain to lighten, and remember to turn on the fog lights and double flashes when parking on the side of the road to avoid accidents.

Use rear window wipers: If your car has a rear wiper, don't forget to turn it on when it rains.

Generally, SUVs, hatchbacks, MPVs and other models are mostly equipped with rear wipers, this is because the rear windshield of the sedan has air flow through, while the hatchback or SUV does not, which leads to the fact that once there is rain, the sedan can use the air flow to blow down the water droplets, but the hatchback cannot, the water can not be blown off in time, it will be easy to stick to the dust, affect the sight of the rearview mirror, and lead to unsafe driving.

Common faults of car wipers are:

A1) Not working at all. There is no cleaning fluid or motor damage.

2) The amount of cleaning solution sprayed is insufficient. There is a blockage in the pipeline. The sprinkler outlet is blocked by dust and mud, and can be dredged with pins and other items.

3) The spray direction of the cleaning solution is wrong. Adjust the correct spray angle.

Summary. Hello dear I am happy to answer for you, the car has a wiper fault code, but the wiper function is normal, the reason is that the glass water is insufficient; Glass alarm sensor damaged; The wiper motor is damaged. The wiper refers to the sheet structure installed in front of the windshield, which is composed of a motor, a reducer, a four-link mechanism, a wiper arm spindle, and a wiper blade assembly.

Its main function is to sweep away rain, snow and dust from the windshield that obstructs the view. The wiper needs to be replaced: the wiper has a long life and the wiper blade is aging; The wiper strip above the wiper has a lie pattern; When using the wipers, scratching the glass makes a screeching sound; There is an indentation where the wiper blows; Wipers shake and jump when in use

The wiper needs to be replaced: the wiper has a long life and the wiper blade is aging; The wiper strip above the wiper has a lie pattern; When using the wiper, the scratching glass makes a screeching sound; There is an indentation in the position where the rain trap bye wiper blows; Wipers shake and jump when in use

The glass water sensor is no problem either.

Although the wiper is only used on the rain, the usual maintenance can not be forgotten to do, so as not to get the wiper "strike" on a rainy day, it will be troublesome. Wipe the wiper blade with glass washer when washing the car, and also check the status of the wiper and whether the wiper rod has uneven swing or leakage. The occurrence of either of these two faults means that the wiper blades are damaged.

In order to check whether the wiper is normal to Qingchang, the owners can spray out some cleaning liquid, and then turn on the wiper, pay attention to whether its action is smooth, and pay attention to whether there is a "scrape" sound, if there is, it means that the wiper is too pressed against the glass, and it needs to be blinded. When the wiper is swept one or two times, observe whether there will be some scratches, and see if there is any moisture left on the windshield, if it is obvious, it means that the wiper strip on the wiper has aged, and the chain should be sharpened and replaced with a new strip. There are other wiper problems as well

The motor is no problem either.

Is there enough glass of water?

Ample. Will the fuse be burned before the fault code will be reported.

Kiss You check whether the wire is loose or poorly contacted, whether the wiper control switch is damaged, no problem, but you can't find the reason.

Kiss you can change the wiper blades and try it

How many days has this faulty lamp appeared?

It would be nice to just change the wiper blades.

The wiper noise is too loud to solve:

1. Wipers are consumables, whether they are bone-based wiper blades or boneless wiper blades, they generally need to be replaced in 3-12 months, which is more quality and use, and should be replaced in time.

2. There is also a small trick to eliminate the vibration and noise of the wiper blade, and use pliers to adjust the gap between the joints and the rubber sheet.

3. Remember not to dry scrape, so that the fine sand on the glass will accelerate the damage to the wiper blades, shorten the replacement cycle, and affect the use at critical moments!

4. Wipers are not only used when it rains, especially in North China, where there is often haze and fine sand, and the frequency of use will be higher, which will accelerate the replacement cycle.

Extended information: The owner in the daily car wash and maintenance process, did not clean the glass well, resulting in some dirt and attachments on the front windshield of the car, resulting in a decrease in glass finish, at this time the owner used no matter how good the wiper is useless, the glass cleaning is not only affecting the owner's driving vision, but also may cause damage to the wiper.
