In this wet autumn rain season, the most annoying thing for car owners during driving should be the phenomenon of fogging the front windshield. , Indeed, the temperature inside and outside the car is different, and the fog will soon "kiss" the glass of your car, but most cars now have a defogging function, so this trouble is for car owners who know a little about the functions of their car It’s nothing to say, but recently several car friends reported a similar problem in the director’s car chat group at the same time: in these days during the autumn rainy season, as soon as my wiper is turned on, it feels like it’s rubbing against the glass. Li watched the wipers wiggle and dance on the glass, with the sound of rubber tapping against the glass.
The main reasons for the phenomenon of wiper jumping and glass rubbing can be summed up in three points. One is that the front windshield of the car is not clean enough; The strength is gradually declining with the increase of the age of the vehicle.

If the car owner finds that the wiper rubs against the glass and jumps while driving in the rainy day, then he must find a nearby place that can protect the car from the rain and park the car. After parking, the first thing we got out of the car to check was not the wipers, but the front windshield. Many car owners have this experience. As long as it is rainy season, after the front windshield is scraped by the wiper, a foggy "dirty film" will appear. No matter how much wiper water is sprayed, it will only be temporarily cleaned. After that, another layer of annoying "dirty film" appeared. This layer was actually accumulated on the front windshield during the driving process before the rainy season. The oil pollution from the industrially developed areas, as well as the dust pollutants in industrially developed areas, are adsorbed on the glass to form a "dirty film", which is difficult to find when it is not raining. Once it rains, this "dirty film" will appear. When the wiper strip scrapes these impurities, the front windshield will fluff. Over time, the wiper strip itself will also be damaged, and the phenomenon of the wiper scraping against the glass and beating will gradually appear.
So how to solve the problem of "dirty film" on the front windshield? In order to avoid the formation of ", it is best to scrub the front windshield with clean water once a week. In some areas with serious air pollution, car owners can properly drop alkaline cleaners into the clean water.
If the front windshield is often cleaned and the wiper rubs against the glass and jumps, then we need to check whether the wiper strip has aged. In the auto supply store, if you are interested, you can observe the brand-new wiper strips. The new wiper strips are full of elasticity when pinched by hand (of course, some inferior products are not ruled out). The new wiper strips are soft, so they can be well Cleans sticky dirt, bird droppings and dust from the front windshield with ease. The wiper strips will gradually age and lose their original elasticity as the climate changes in spring, summer, autumn, and winter. When the elasticity is insufficient, the wiper strips will become the "personal killer" of the front windshield. Dust will damage the front windshield when the wiper strips are scraping the glass, and the scratched glass will be refracted by light during driving, which will affect the driver's visual judgment. Therefore, it is necessary to replace the wiper strips regularly. It is an important item to protect the front windshield and protect driving safety. Generally speaking, the lifespan of ordinary brand wiper strips is within one season, but the actual replacement cycle depends on the usage of the wiper strips. If your front windshield The glass is already very clean, but the wiper is still scratching the glass and beating when you turn it on, then you should replace the wiper strip immediately, and don't cause greater losses to save tens of dollars.
When the owner observes that the front windshield and the wiper strips are all right, and the problem still cannot be solved, then we need to focus on the wiper spring equipment. The wiper spring is very unfamiliar to most car owners. This device is under the wiper arm. Because this device is not included in the maintenance scope of many car brands in the later maintenance, few car owners will take the initiative to check the wiper spring. This has also led to the phenomenon that car owners are confused after the spring elasticity of the wiper blades declines. The function of the wiper spring is to generate down force, and press the front wiper strip tightly on the front windshield. When the spring declines and the elasticity is insufficient, it is difficult to press the wiper strip, so that the wiper There is a gap between the strip and the glass, so that the wiper will rub against the glass and jump in the working state.
Generally speaking, the wiper spring has a long service life, and it will not decline after 7 to 10 years. However, due to various objective factors such as the owner's usage habits and the vehicle environment, the component will decline early. Generally speaking, the director recommends it to everyone. The car owner checks once a year, lifts the wiper as a whole, checks whether the spring part is rusted, and gently puts it back on the front windshield. The windshield is parallel to the windshield. Observe the gap between the wiper strip and the glass. If there is an obvious gap, you need to go to the car factory to replace the wiper spring.
After the above three key parts have been checked, it is basically possible to keep car owners away from the rainy weather.
