What s going on with the wiper not working, what s going on with the wiper not moving

The reasons why the wiper does not move are: 1. It may be that the fuse is broken, causing the wiper to not work normally; 2. It may also be caused by the motor being burned out, but this probability is relatively small; 3. It may be that there is a fault in the place where the wiper connecting rod is connected, resulting in the wiper not working normally. 4. It may be that the wiper switch is faulty.

5. It may also be caused by faulty wiper lines.

The wiper does not move the workaround:

1. Open the fuse box to check, if the fuse blows, you need to replace it, and before replacing, you should close all the electric doors of the car.

2. If the motor is damaged, it is best to go to the auto repair shop for inspection and repair.

3. Pay attention to the maintenance of the wiper blade of the car, if it is seriously damaged, it will not work normally, and it needs to be replaced with a new pair of wiper blades.

4. Check the wiper connecting rod, and you can judge whether it is a side rod fault by checking the operation of the wiper.

5. If the wiper switch is faulty, you can use a multimeter to measure the quality of the switch, or you can directly replace it with a new one to test.

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.

The reason why the wiper does not move is that it is damaged, there is a problem with the power supply, and the mechanical system connecting the wiper motor and the wiper arm is loose.

Start the motor in the plugged in situation, and then try to open the engine cover to scrape the wipers, if it is not broken, you can hear the sound of the motor turning, and the sound is very significant, if there is no sound, accompanied by a hint of burning smell, it is likely that the motor is destroyed.

If the wiper does not move, it is likely that the fuse (to prevent the circuit from being overloaded) is blowing, which causes the wiper to not work properly, at this time we have to open the fuse box to check whether the corresponding fuse (with the instruction manual on the cover of the collapsed bump body) is fused.

How it works

The power source of the wiper comes from the electric motor, which is the core of the entire wiper system, and 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 integrated with the worm gear mechanical part. The function of the worm gear mechanism is to decelerate and increase torsion, and its output shaft drives the four-link mechanism, and the continuous rotary motion is changed to the left-right swing motion through the four-link mechanism.

Under normal circumstances, there is a wiper to control the twist on the handle of the car combination switch, with 3 gears of low speed, high speed and intermittent, and the top of the handle is the scrubber key switch, and the washing water sprays out when the switch is pressed, and the windshield is washed with the wiper.

If the wiper does not move, it may be caused by damage to the wiper motor itself, or by damage to the control module integrated with the motor.

The wiper assembly includes an electric motor, a reducer, a four-link mechanism, a wiper arm mandrel, a wiper blade assembly, etc. When the switch of the wiper is pressed, the motor starts, and the speed of the motor drives the swing arm through the deceleration attitude of the worm gear and worm car torsional action, and the swing arm drives the four-link mechanism, and the four-link mechanism drives the rotating shaft installed on the front dash plate to swing left and right, and finally the wiper blade is driven by the rotating shaft to sweep the windshield.

The failure of any part of the wiper assembly will lead to the abnormality of the wiper, and the most likely cause of the wiper not moving is the damage of the wiper motor itself, or the damage of the control module integrated with the motor. If the wipers don't move, open the fuse box to check and replace it, but remember to turn off all the electric valves of the car before replacing them.

Precautions for the use of wipers

1. Do not open the wiper directly without spraying glass water, so that dry scraping can easily lead to abnormal wear of the wiper film and damage to the wiper motor;

2. If the front windshield is too dirty, it is best to gently and simply clean the dirt on the windshield with a dry cloth to reduce the wear and tear of the wipers.

3. When the wiper blade has poor wiping, try to soak the wiper blade with water slag first, polish the wiper blade back and forth with water sandpaper, and then clean it with clean water and put it back into the windshield, and then try to scrape it to see if there is an uneven place.

There are several reasons why the wiper won't move:

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 assembly is equipped with an electric motor, a reducer, a four-link mechanism, a wiper arm journal, a wiper blade assembly, etc. When the power switch of the wiper is pressed, the motor runs, and the speed ratio of the motor pushes the lower swing arm through the speed reduction and torsion increase effect of the rack and pinion, and the lower swing arm drives the four-link mechanism, and the four-link mechanism drives the transmission shaft installed on the front cover plate to shake up and down, and finally the wiper blade is driven by the transmission shaft to sweep the windshield of the car.

Common faults in any position of the wiper assembly will definitely cause the abnormality of the wipers. 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.

Wipers are more common in our lives, we need to use wipers on rainy days, and we also need wipers when cleaning windshields. Wipers are very important for cars, so when there is any problem with the wipers, we need to repair them in time. If there is a problem with the wipers, we have to go to the car repair shop in time to repair it.

If you find that there is a problem with the car, quickly repair it, if you find that a certain part of the car is abnormal or there is an abnormal sound when you are driving, you should go to the car repair shop to check it. Avoid unnecessary surprises.

1. There is a problem with the power supply of the wiper motor, which is commonly caused by the insurance damage of the wiper motor, resulting in the wiper being unable to work normally; 2. Caused by damage to the wiper motor itself, damage to the motor itself or damage to the control module integrated with the motor; After checking and confirming the damage, it can be replaced; 3. The mechanical structure connected between the wiper motor and the wiper arm falls off, is not installed in place or is damaged only by the limb; 4. The power switch of the windshield hill core is damaged by itself or the power supply system is damaged; 5. Problems occur in the wiper motor route, such as short circuit or short circuit fault in the power supply system or negative electrode route. The accuracy rate of motor burnout is very low, but it can also be a problem for quality control. For how to judge, first put the vehicle starting motor in the plugged in situation, and then try to open the hood cover to scrape the wipers, if it is not broken, you can hear the sound of the motor turning, and the sound is very significant.

But if there is no sound, and with a hint of burnt mush, it may be that the motor is destroyed. Generally speaking, if the fuse wire is not melted, it is best to go to the car repair shop for an inspection, after all, others are specialized. The fuse wire burned out and the motor was damaged.

The wipers didn't move. It is likely that the wiper is not working properly due to the fuse wire (to avoid the load on the power circuit). At this time, we need to open the fuse box and check whether the matching fuse wire (which is actually indicated on the outer cover) is fused.

If so, replace it, but remember to turn off all power switches on the vehicle before replacing. In fact, the possibility of motor damage is very low, but there may also be quality management challenges. For how to judge, first turn on the starter motor, and then try to open the cover and scrape the wipers.

If it is not broken, you can hear the sound of the motor running, and the sound is significant. But if there is no sound, with the smell of burning, it is likely that the motor has been destroyed.

Why are the wipers not working:

1.It may be that the fuse is broken, causing the wiper to not work properly;

Solution: Open the fuse box to check. If the fuse blows, replace it. Before replacing, turn off all switches on your car.

2.It may also be caused by the motor burning out, but this probability is relatively small;

Solution: If the motor is damaged, it is best to go to the auto repair shop to check and repair;

3.It may be that there is a fault at the connecting rod of the wiper that causes the wiper to not work properly;

Solution: Pay attention to the maintenance of the wiper blades of the car. If they are badly damaged and do not work properly, they need to be replaced with a new pair of Yuchang fierce skin scrapers. Check the wiper connecting rod, and you can judge whether it is a connecting rod failure by checking the working condition of the wiper;

4.The wiper switch may be faulty, causing the wiper to not move;

Solution: The wiper switch is faulty. You can use a multimeter to measure the quality of the switch, or you can directly change it to a new one to test.

5.It may be that the wiper circuit is faulty, and the wiper does not move;

Solution: The wiper has a line fault point. Use a car multimeter to measure voltage, resistance, and current, and check with the actual situation.
