How to repair the wiper motor in the first and second gears?

The reason is. 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.

4. During the test, place the wiper switch 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.

5. Check the wiping status and whether the wiper rod has uneven swing or missing scraping. If the following three conditions occur, this wiper is not qualified. 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.

6. During the test, attention should be paid to whether the motor has abnormal noise, especially when the wiper motor "buzzes" 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.

7. Wiper blades are not always as long as possible. Although lengthening the length of the wiper blades can increase the visible range, it will also increase the burden on the wiper motor and wiper lever. Of course, it is possible to lengthen it, but it must be guaranteed that it must not interfere with the normal operation of the wipers.

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.

3. If the wiper strip is sticky with sand and gravel, wipe the strip with paper.

4. If the size of the wiper strip is not suitable, replace the wiper blade.

5. If the glass is too dirty, clean the glass in time.

The above situation is recommended that you check it, you can give priority to these three points, if it is not good, the probability of the wiper adhesive strip itself is larger, it is recommended to replace it.
