Now more and more people like DIY, and car owners are more and more self maintenance. Today, let's summarize the precautions for replacing car wipers:

1. Buy matching wipers

Before buying a wiper, you should determine what kind of wiper arm your car is equipped with in the original factory. When buying a wiper, you should pay attention to selecting a wiper that is suitable for your own model, or you will spend money to install it, which is very annoying.

2. Bare wiper arms can break the glass

The spring force of the wiper arm is very large, so no matter what kind of wiper is, after the wiper strip is removed, the exposed wiper arm should be gently placed back on the windshield to ensure safety. If you don't put it back and accidentally touch it, the wiper arm will bounce back to the glass, and the probability of breaking the glass is very high. This is pure iron hitting the glass!

3. The concealed wiper arm needs to be switched on "maintenance mode" to replace the wiper

The wiper arm of some models is of hidden design. The wiper arm is hidden in the engine cover when it is closed. At this time, it is impossible to lift the wiper arm to replace the wiper. At this time, it is necessary to adjust the wiper arm to "maintenance mode" before normal replacement. There are differences in the operation modes between brands. We take Volkswagen series models as an example: first, ensure that the vehicle is idling, then turn the key to the "off" position with the ignition off, but be careful not to remove the key. At this time, press the wiper control lever to the "point brush" position, and the wiper will swing up and stop at the vertical position before replacement. After replacement, the wiper will reset when it is powered on again.

4. Test brush and check after replacement

After replacing the wiper, be sure to open the wiper for inspection. It is better to spray glass water to check whether there is looseness in installation or whether the wiper strip is loosely attached. If the installation is not inspected, in case of installation problems, you will be fooled when using it, which will affect safety.

5. Hands will be dirty when replacing the wiper

There is another detail to remind you that the wiper strip is made of black rubber and will fade. When replacing the wiper, it is hard to avoid getting a lot of black marks on your hands. Such a hand is very boring wherever you touch it... My personal experience is to replace it before parking at home and wash your hands directly after replacement, If you need to change it when you go out, it is recommended that you wear gloves or find a piece of toilet paper to cover it before changing, so as not to get your hands dirty.

6. When should I replace the car wiper

Generally speaking, the service life of automobile wiper is about 1 year. After exposed to the sun in summer and cold in winter, the rubber strip will be aged, fragile, or even broken off. When using the wiper, there will be water left on the glass, many lines affecting the sight, and serious shaking and abnormal noise on the windshield. In case of the above situation, it is recommended to replace the wiper as soon as possible.
