What is the reason why the first gear of the Dongfeng well off wiper does not move, and the second a

Basically, there is a problem with the synovial membrane assembly at the upper end of the wiper motor. Solution: Remove the wiper motor assembly.

Disassembling the circular parts at the upper end of the motor, it can be seen that there are three sets of friction slides inside, which press the slip down to the appropriate position to ensure that the slip tongue is in effective contact with the synovial membrane. Install the reset and it's back to normal. Special reminder:

Take a good picture of the wiper link position before dismantling.

The first gear is the intermittent gear, which uses the low-speed gear of the wiper motor, and the intermittent function in the middle relies on the circuit inside the wiper switch to achieve it. The fault is mostly caused by the wiper switch, check whether the wiper switch itself is damaged, and replace it if necessary.

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.

Hope, thank you.

The second and third gears are normal, which proves that there is no problem with the wiper motor, and the first gear does not respond is the wiper switch problem, and it can be seen that either the line is dropped and fallen off, or the switch contact point is burned out.

It may be a bad catch in the first gear.

Hello, replace the wiper motor, the motor is broken.

If the contact between the first and second gear switches and the line is poor, you can check the toggle switch. 1. First find out what kind of wiper your car uses, you can refer to the car manual to see the wiper model indicated on it. 2. Pay attention to whether the way the struts are connected to the wiper rocker arm matches.

Some of the arms are screwed to the rocker arm, while others are locked with a buckle. 3. Pull up the wiper and touch it with your fingers on the cleaned rubber wiper to check whether there is any damage and the elasticity of the rubber blades. If the blades are aged, hardened, and cracked, the wiper is not qualified.

Have a nice ride

The wiper motor and combination switch have been replaced, and it is useless.

The wiper motor, or the control unit under the steering wheel is damaged.

The wiper relay is faulty and it is recommended to replace it. If you want the wiper to have a longer service life, it is best to avoid exposure to the sun for a long time, and it should be noted that many car owners find that there is sand and dust on the glass, often only turn on the wiper to sweep away the sand particles, in fact, this will damage the wiper rubber strip and car glass, so before opening, you may wish to spray a little cleaning liquid. Of course, manual cleaning is better.

Precautions for the use of wipers.

If there is something sturdy on the windshield, such as dried droppings from birds such as pigeons, do not scrape them directly with a windshield wiper, and clean the bird droppings by hand first. These hard things are very easy to cause local injuries to the thin sheets of the wiper blades, resulting in the wipers not cleaning the rainwater.

The premature scrapping of some wiper blades is directly related to improper car washing. If you do not pay attention to wiping the front windshield when washing the car, the oil film on the surface will be washed off, which is not conducive to the downflow of rainwater, causing the rainwater to stop on the glass surface and increasing the friction resistance between the rubber sheet and the glass surface. This is also the reason why the wiper blades stop momentarily because they can't be scraped.

If the wiper blades do not move and the motor continues to run, it is very easy to cause the motor to burn out.

The root cause is that the gear shaft of the wiper motor is rusty, and the first gear cannot be rotated, and the plastic gear will quickly wear out and be scrapped. In addition, the circular contact piece of the gear is rusty, which will cause a certain gear to be in poor contact and will not rotate.

There is also a return in the motor, and the contact is broken or worn, it is recommended that you remove the wiper motor, see if the contact inside can be cleaned, and try again on the pry up, it is generally good.

Wipers, also known as wipers, water picks, wipers or windshield wipers, are equipment used to brush and scrape 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 construction equipment, such as cranes, are also equipped with wipers.

It should be a problem with the contact of the first gear, the intermittent relay is in the combination switch, and the combination switch has to be replaced, are you looking to see if your wiper can automatically return to its position.

Generally, the resistor is broken, and it is good to replace a resistor.

Hope, thank you.

Summary. Hello, the vehicle's wiper does not move in the first gear, and the reasons and treatment methods related to the normal second and third gears are as follows. The first is the wiper of the vehicle, the problem of the motor leads to this phenomenon and the relevant power supply line needs to be measured, if the power supply line is normal, the wiper motor needs to be replaced.

The second is the phenomenon caused by the rust of the wiper linkage rod, which needs to be replaced. The third situation is that there is a problem with the wiper switch belonging to the vehicle, and there is no gear caused by the virtual connection of the internal contacts, which is the need to replace the wiper switch.

The wiper does not move in the first gear, and the speed regulation in the second and third gears is normal.

The first gear is not energized, and the fuse is burned directly.

Wiper switch, unplug and try it.

Burn the same. Unplug the wiper motor and give it a try.

Pull the motor plug and don't burn, but it doesn't directly and doesn't power on.

Did the motor change.

No, the 1st gear plug is not energized, so I don't understand it a bit.

What's that car model for you? Is there any water ingress?

Jinbei A7 van.

In this case, consider the wiper switch or the relevant connection line, where there is electricity.

Is there a problem with the motor?

The first plug is not energized, and this has little to do with the motor. ,, The first thing to exclude is the motor and the linkage rod, if the linkage rod rust resistance is too large, there will also be this phenomenon.

Hello When the wiper is in normal operation in one or two gears and three gears, the wiper motor of the vehicle is broken, and there are three modes of working switches inside the motor, which are realized through different resistance modes, and only the three gears run directly, so the resistance mode is broken, and the entire motor can only be replaced, and the specific operation steps are as follows: 1. Disconnect the negative terminal post of the battery. 2. Unplug the wiper arm cover.
