The windshield wiper is rattling. What's the matter? What should I do?

The squeaky noise of the wiper is a very common car problem, but it sounds very uncomfortable and affects the driving safety. We can determine the cause and solve the abnormal noise by the following ways.

The abnormal noise of the wiper is generally caused by improper installation of the supporting steel frame of the wiper strip or aging of the framework (or uneven windshield ). It depends on whether the wiper blade rings when it goes up or down.

If it sounds when going up, it means that the wiper bracket is twisted upward, and the wiper stops in the middle position (pull the wiper control panel towards the steering wheel after the car stops), and then gently pull it up. Wrap the wiper frame with cloth or soft things, hold it with a spanner or pliers, pull it down a few times, and try to scrape it after reset. Is the abnormal noise smaller? If so, repeat until the noise is eliminated. If it starts to ring when it goes down, it means that it has turned too far and needs to be turned in the opposite direction. Until the abnormal noise is eliminated! If it's going down, twist it up in this way.

If the wiper up and down have a sound, the wiper can only be replaced!!!
