First, the wiper is aging.
As a consumable, the car wiper will inevitably age with the increase of use time, which will lead to abnormal noise in its working process. If this is the case, we just need to replace it with a new wiper. Of course, if the vehicle is still under warranty, you can apply for a claim or free replacement from the 4S shop.
Second, the wiper is improperly installed.
Incorrect installation of a new wiper can also cause it to make an abnormal noise when it is working. In this case, we can try to solve the problem by reinstalling the wipers. During the process of reinstalling the wipers, we need to adjust the angle and pressure of the wipers to ensure that they work properly and do not create excessive friction with the windshield.
3. Foreign objects are mixed between the wipers and the windshield.
When there is a foreign object between the wiper and the windshield, it may also cause the wiper to make an abnormal noise when working. At this point, we need to check whether there is any foreign object between the wiper and the windshield, and if so, we need to clean it up in time. Be careful not to damage the wipers and windshield when cleaning to avoid greater damage.
Fourth, the wiper motor failure.
If the wiper motor fails, it may also cause abnormal noises when the wiper is working. At this point, we need to check if the wiper motor is working properly. If the motor fails, the motor needs to be replaced or repaired. It is recommended to go to a regular car repair shop for repair to ensure the quality of repair.
Fifth, the wiper connecting rod is loose.
Loose wiper connecting rods may also cause abnormal noises when the wipers are working. At this point, we need to check whether the connecting rod of the wiper is secure. If the connecting rod is found to be loose, the connecting rod should be tightened or replaced in time. Pay attention to safety when tightening or replacing the connecting rod to avoid unnecessary injury.
