How is the Buick Excelle wiper gear useless

The first gear is intermittent, scrape once, stop and scrape again; If the first gear does not move at all, there is a problem, so make sure it first.

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.

There was a problem with the wipers.

The things you need to pay attention to when buying a car are as follows:

1. Confirm the purchasing ability

Determine the purchasing power, after buying a car does not affect the overall quality of life of the family, generally according to the average income of the family in the past three years, generally take out 20% of the family for three years, but not more than 10% of the value of the family's fixed assets.

2. Concerns:

The most important thing for a family car is safety, followed by affordability, because the safety of the car carries the life of a family, so safety is the top priority.

3. On-site confirmation:

According to the above two steps, basically determine the several models to buy, and go to the 4S store to confirm on the spot, including test drive, inquiry, loan, repair and maintenance, and other related information.

Basic Structure:

Taking the electric windshield wiper as an example, its basic structure and working principle are introduced.

The electric windshield wiper is driven by a motor, which is generally composed of wiper arm wiper arm, wiper blade assembly, rubber brush blade, brush blade bearing, brush blade support, wiper arm mandrel, wiper bottom plate, motor, deceleration mechanism, drive rod system, drive rod hinge, wiper switch and wiper switch knob.

Of course, the wiper with wiper ECU is also equipped with an electronic control unit ECU. The electric windshield wiper is driven by an electric motor, the left and right wiper blades of the wiper are pressed against the outer surface of the windshield by the wiper brush arm, and the motor drives the deceleration mechanism to rotate, and through the drive rod system to make reciprocating motion, driving the wiper brush arm and the wiper blade to swing left and right to scrape the windshield glass.

The wiper is driven by the motor, and the rotary motion of the motor is converted into the reciprocating motion of the scraper arm (that is, the part on the windshield except for the scraper) through the connecting rod mechanism, so as to realize the wiping action. Generally, the motor is turned on (that is, the wiper work switch is pressed) to make the wiper work. By selecting high-speed and low-speed gears.

My car situation is the same as yours, now I have changed the wiper switch assembly but the problem is still not solved, is it a problem on the motor, check that there is no wiper intermittent relay. Please advise!

I'm the same way, it's good to change the assembly, it's the same in two days, it shouldn't be a problem with the assembly.

My Kaiyue wipers are also sick like this.

The main congratulate to check the wiper motor, with the test lamp to measure whether there is electricity in the first and second gears, if there is no electricity, you need to check the wiper switch under the mess, if there is electricity, it is a wiper motor problem. Happy with your car. [Car questions, ask the master of the car reputation.]

4S shop professional technician, 10 minutes to solve. 】

1. When the windshield is dry, the wiper switch shall not be turned on, if you need to test the working condition of the wiper, you should first warm the glass with water, otherwise it will traumatize the glass, and at the same time, due to the large friction resistance of the wiper, it may damage the wiper blade or burn out the wiper motor.

2. The wiper motor is mostly a permanent magnet motor, and the magnetic pole of the motor is made of ceramic material, which is easily damaged by impact. Therefore, in general, do not remove the motor at will. If it is necessary to remove it, avoid falling or colliding with the motor from a height.

3. The wiper motor is mostly enclosed and cannot be disassembled at will. When it must be disassembled for maintenance, the inside should be kept clean, and dirt such as iron filings should not fall into the casing. The fit of each part should not be too tight during assembly, so as not to burn out the motor due to excessive rotational resistance, and at the same time, lubricating oil should be added to the oil-impregnated bearing linoleum to supplement or replace the grease in the deceleration mechanism.

Kaiyue wiper intermittent and slow gears could not work normally, and when the motor was disassembled, it was found that the contact piece that detected the position of the motor was loose.

Remove the upper cover of the wiper motor assembly (the part where the cable plug is plugged in) and eliminate the need for the entire motor.

The contact tabs on the board have become loose and can even be unplugged.

Since the cable connector has been filled with epoxy resin for sealing needs, the circuit board cannot be removed for soldering, so a hole needs to be dug in the upper cover of the wiper assembly until four solder joints are exposed. After the contact piece is soldered, the entire exposed hole is filled with hot melt adhesive. This is a must, because this hole is facing the sky, and it is not a joke to enter the rain.

Replace the upper cover of the repaired wiper motor assembly with the motor assembly and plug in the cable. Cover with a rain collector and attach a sealing strip. Attach the wiper skeleton with a 14mm wrench and everything will be back to the way it was. Try the wiper again.

Hello, hello, according to your description, most of this situation is a problem with the wiper motor, because the relay of the wiper motor and the wiper motor of this car are integrated, so this situation can generally be solved by replacing the wiper motor.

Buick Excelle wiper The intermittent gear is gone, and it is directly the same speed as the second gear, what is the reason and how to solve it? Thank you!

Hello, happy to answer your questions.

Hello, dear, the exclusive technician of the car master will serve you, attentively, carefully and attentively to answer your car questions and provide you with satisfactory service! I hope my answer can help you! Hello, hello, according to your description, most of this situation is a problem with the wiper motor, because the relay of the wiper motor and the wiper motor of this car are integrated, so this situation can generally be solved by replacing the wiper motor.

Intermittent failure of the Kaiyue wiper can be caused by the following reasons:1. There is a short circuit inside the motor.

2.The wiper blades are damaged. 3.

Sidebar failure. 4.The wiper fuse blows.

5.There may be a problem with the wiper switch. 6.

The wiper circuit is faulty. Intermittent failure of the wiper is a very common problem in the use of the wiper.

Solution to intermittent failure of Kaiyue wipers:

1.Short circuit inside the motor: After opening the hood, you can see the wiper motor, and you can touch the rain wiper motor with your hands. If it feels hot, it means that the motor is short-circuited, and replacing the motor can solve the problem.

2.Wiper blade damage: Usually we don't pay attention to the maintenance of car wiper blades. If it is found to be badly damaged on a rainy day, it will not work properly. Just replace a pair of wiper blades in time.

3.Side rod limb should be cautious of failure: replace the wiper connecting rod in time.

4.Wiper fuse blow: You can check whether the wiper fuse is blown or not, and you can replace the fused fuse with the spare fuse on the car.

5.There may be a problem with the wiper switch: If the above inspection does not find a problem, it is time to consider that there may be a problem with the wiper switch. You can use a multimeter to measure the quality of the switch, or you can directly use a new test.

6.Wiper circuit failure: Checking the rain filial piety wiper circuit is a complicated and time-consuming thing. You need to be able to use a car multimeter skillfully, measure voltage, resistance, and current, and find out the fault points of the wipers that cause them to not work.

1. Check the wiper motor. After opening the car cover, you can see the wiper motor, you can touch the wiper motor with your hands, if you feel hot, it means that the motor is short circuited inside, and replacing the motor can solve the problem. 2. Check the wiper blades.

Usually do not pay attention to the maintenance of car wiper blades, rainy days found that it has been seriously damaged, can not work normally, timely replacement of a pair of wiper blades can be.

Check the wiper base linkage. There are many connected places in the wiper link, and if there is a problem in these places, the wiper cannot work properly, and you can judge whether it is a side rod failure by looking at the operation of the wiper.

Check the wiper fuse. In order to protect the car line, each electrical equipment is equipped with a fuse, if the wiper can not work, you can check whether the wiper insurance is blown, and you can replace the fused with the spare insurance on the car.

Check the wiper switch. Although the wiper switch is not often used, the automotive electrical appliance itself is unstable, so when no problem is found in the above inspections, it is necessary to consider that there may be problems with the wiper switch.

Check the wiper lines. Checking the wiring is a complicated and time-consuming matter, and it is necessary to be able to skillfully use the car multimeter, which can measure voltage, resistance, and current, and be able to combine it with reality, so as to find out the fault point of the line that causes the wiper not to work.

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.
