Precautions for replacing car wiper

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 wiper
Before purchasing the wiper, you should determine which wiper arm your car is equipped with in the original factory. When selecting the wiper, you should pay attention to selecting the wiper that is suitable for your model, otherwise it will be annoying if you spend money to install it.
2. Exposed wiper arm will break the glass
The spring force of the wiper arm is very large, so no matter which type of wiper, after removing the wiper strip, the exposed wiper arm should be gently put back on the windshield to ensure safety. If you don't put it back and accidentally touch it, the wiper arm bounces back onto the glass, and the probability of breaking the glass is very high. This is pure iron hitting the glass!
3. The hidden wiper arm needs to be switched on "maintenance mode" to replace the wiper
The wiper arm of some models is of hidden design, and the wiper 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 operation modes between brands. Let's take the Volkswagen series models as an example: first, ensure that the vehicle is idling, then turn the key to the "OFF" position when the engine is turned off, but be careful not to remove the key. At this time, press the wiper control lever to the "spot brush" position, and the wiper will swing up and stop in the vertical position before replacement. After replacement, the wiper will reset when it is powered on again.
4. After replacement, test brush and check
After replacing the wiper, be sure to turn on the wiper and check it. It is better to spray glass water to check whether there is loose installation or the wiper strip is not tightly attached. If the installation is not checked, in case of installation problems, it will be silly when using it, affecting safety.
5. Your hands will be dirty when replacing the wiper
There is another detail to remind you that the wiper bar is made of black rubber and will fade. When replacing the wiper, it will inevitably get a lot of black marks on the hand. Such a hand is very boring everywhere it touches... My personal experience is to replace it before going home and parking, and wash your hands directly after changing it; If you need to change it when you go out, it is recommended that you wear a glove or find a piece of toilet paper to pad it before changing to avoid getting your hands dirty.
6. When should I replace the car wiper
The service life of the car wiper is generally about one year. After exposure to the sun in summer and cold winter, the rubber strip will be aged, fragile, or even broken off. When using the wiper, there will be water left on the glass, there will be many lines that affect the vision, and the wiper will shake and make abnormal noise on the windshield glass. In case of the above conditions, it is recommended to replace the wiper as soon as possible.
