Abnormal sound of soft flat wiper blade
Over time , various problems will appear in the car ;
The wiper blade is one of them that cannot be ignored .
Sometimes unable to start ，
But no problem , let ‘ s analyze the abnormal sound .
Wiper blades are consumables .
Common problems are dirty brushes , severe wear , and abnormal noise .
The correct method is to perform regular maintenance and pay attention to replacement .
There is only one vertical force point for soft flat wiper blade ;
Easy tremor at the tip is an important factor for abnormal noise .
Check for foreign objects such as leaves and small stones between the wiper blade and the windshield .
The above will also cause abnormal noise , which needs attention .
The aging wiper blade has some bending and hardening ,
which is also an important factor that causes sound .
The wiper motor is located directly under the water tank .
If an abnormal sound is found when the wiper is turned on , it may also be emitted .
Pay attention to the linkage of the wiper
Its spring performance will decline with time ,
Wear of bushings , etc . can also cause abnormal noise .
It is worth mentioning that the wiper blade itself ,
The wiper blades are replaced every 6 to 12 months ,
If you don ‘ t change it for a long time ,
As the rubber ages , hardens , and makes abnormal noises , the wiper blade effect will decrease linearly .
Regular maintenance of the wiper blades and attention to replacement are the top priorities .
