Maintenance personnel recommend that in order to ensure your driving safety, it is best to replace the wiper blades once a year.
How to choose a wiper blade
1. First find out what type of wiper blade your car uses. You can refer to the car manual. Check the wiper model number indicated above.
2. Pay attention to whether the way the support rod is connected to the wiper rocker arm matches. Because some arms are fixed to the swing arm with screws, while others are locked with male buttons.
3. Pull up the wiper blade and touch the cleaned rubber wiper with your fingers to check for damage and the elasticity of the rubber blade. If the blades are aged, hardened, or cracked, the wiper is unqualified.
4. During the test, place the wiper switch at various speed positions and check whether the wiper maintains a certain speed at different speeds. Especially in intermittent working conditions, pay attention to whether the wiper maintains a certain speed when moving.
5. Check the wiper status and whether the wiper rod swings unevenly or misses the wiper. If the following three conditions occur, the wiper blade is unqualified. First, the swing is not smooth and the wiper beats abnormally; second, the contact surface of the rubber and the glass surface cannot fully fit, resulting in wipe residue; third, the glass surface appears in a water film state after wiping, causing fine streaks, fog, and Linear residue.
6. During the test, attention should be paid to whether there is any abnormal noise from the motor, especially when the wiper motor buzzes but does not rotate. This shows that the mechanical transmission part of the wiper is rusty or stuck. At this time, the wiper switch should be turned off immediately to prevent burning the motor.
7. Some people think that the longer the wiper blade, the larger the wiped area and the better the field of view. In fact, the longer the wiper blade is not, the better. Although lengthening the length of the wiper blade can increase the visible range of the field of view, it will also increase the burden on the wiper motor and wiper rod. Of course, you can extend it, but you must ensure that it does not hinder the normal operation of the wiper.
