The wiper refers to the chip structure installed in front of the windshield, which is composed of motor, reducer, four-bar mechanism, wiper arm mandrel, wiper assembly, etc., and its main function is to sweep away the rain, snow and dust that hinder the view on the windshield. The lifespan of the wiper blade varies according to its own quality and use environment, but the general life span varies from 2 to 4 years. During the heavy rain on the way back to Kunming from Chengdu during the holiday, it was found that Rain Water of the glass was unevenly polished, considering that the wiper might need to be replaced.
When I took my leave, I asked du Niang.
When should the car wiper be replaced?
1. When the wiper works for a long time, the surface needs to be replaced when it is deformed under pressure, and when the surface is scratched by a hard object.
2. Pull up the wiper and touch it on the cleaned wiper rubber with your finger to see if there is any damage and how the rubber blade is elastic. If the blade is aging, hardening and cracking, it needs to be replaced.
3. During the light rain, it was found that the wiper left uneven marks on the glass surface, affecting the field of vision, which indicated that the wiper had hardened and needed to be replaced.
4. Abnormal noise occurs when using wiper
5. When the tension of the wiper arm spring weakens, the wiper arm needs to be replaced.
Although the car has only been used for more than a year, because the daily parking is on the ground, the windshield happens to face the sun, and the daily exposure is inevitable. In addition, there is uneven wiping, and the sound is particularly loud, so it is estimated that the wiper is seriously aging. So I decided to replace the wiper.
Turn on the power supply, that is, without stepping on the brakes, directly turn the knob. Place the wiper in the repair position.
Because there is no P-diagram and notes, it is annotated directly at the bottom of the picture.
Although this time only replaced the wiper tape, but even after a personal practice, it is divided into two parts.
The noun explains:
Wiper is in a broad sense, this article only represents wiper bracket and adhesive strip.
I. overall replacement of wiper
There is no need to elaborate on this step, it is recommended to build a thicker towel on the glass, beware of misoperation, the wiper bounces back to break the glass.
There is a square button on the back of the wiper, press it hard and push it up to push the pin out of part, as shown in the picture, because there is a hose connection below, so it is impossible to get there in one step.
The lower part of the card pin also has a button, both hands press, push to the direction of the car body, you can expose the lower hose.
Gently remove the hose and do not use brute force. Repeat action one at this time, continue to push the wiper upward, and the wiper can be removed as a whole.
At this point, if the whole kit is replaced, it will be almost finished. Connect the new wiper to the card, connect the water pipe, and OK.
But as us, we will not be satisfied with this, so keep going.
II. Replacement of wiper tape
Why to write the replacement of tape, the replacement of the overall wiper is convenient to save time and effort, but as a new car in less than two years, it is really a bit wasteful. For the purpose of exchange, study and research, we go on, how can we save money?
There is a prompt on the head of the wiper. Press the button gently in the direction of the arrow to remove the bamboo shoots.
Remove the bamboo shoots and gently pull out the wiper tape.
After pulling out the tape, I forgot to take a picture. The two strips are not of the same length, but one is long and the other is short. The same is true of the new wiper.
The careful friend found that the aqueduct of the wiper has many white dots, some of which have seriously blocked the water flow function of the conduit, because of the poor local water quality and many impurities, and the other is the frequent use of precipitates such as wiper essence. The needle of the mobile phone card is just used to dredge the keyhole and dredge the keyhole one by one to ensure the effect.
Simply did a test, the effect is very obvious, each outlet hole is very smooth.
What I want to do, needless to say, look for the same money.
Three or three days later
It’s not easy to find this note. There is no same money or alternative money at all. In the end, it was searched by model.
Awkwardly, the quality of the product is really not as good as that of the original factory, and the tape bought has grown by about 1 cm. Is this a leeway left for us by the manufacturer? Don’t say a word-cut it off.
Press the wiper bracket guide to insert the new wiper strip.
Stuffed with bamboo shoots, the wiper strip has been replaced at this point, is it very simple?
The effect is very good, there is no abnormal noise, no noise, and the glass is refreshing.
The replacement of wipers varies from person to person, depending on the demand, at least changing the tape can solve the problem before the elasticity of the wiper bracket decreases. There is no need to replace the overall kit, perhaps the quality of the deputy factory is unreliable, the advantage is the price, ah, estimated to be close to 1: 10. Besides, you can find a sense of achievement and happiness by doing it yourself. Why not?
