What should I do if the wiper makes abnormal noise?

The solution is as follows:

1, and replace it in time according to the quality and usage;

2. Narrowing the gap between each joint and the rubber with pliers can reduce the sound. Remember not to dry scrape, otherwise the fine sand on the glass will accelerate the damage of the wiper blade and shorten the replacement cycle. If the car owner does not properly clean the glass during the daily car washing and maintenance, there will be some dirt and attachments on the front windshield of the car, which will lead to the decrease of glass smoothness. If the glass is not cleaned, it will not only affect the driving sight of the owner, but also cause damage to the rain and noise.
