The noise of the wiper is generally caused by the aging and deformation of the wiper strip itself, or caused by the presence of foreign objects between the wiper strip and the windshield; you can first check whether there is a foreign object between the wiper strip and the windshield, and then raise the wiper to the maintenance position, and check the wiper strip. Whether there are hardening, burrs, nicks, cracks or tears in the rubber strip, if there is, the wiper blade needs to be replaced. The other is the oil film on the windshield glass; if the cause of the wiper blade is ruled out, the windshield glass can be sprayed with water In the test, if it is found that there is no water on the glass, or the water will spread quickly, it means that there is an oil film on the windshield, which causes the wiper blade to shake or make abnormal noises. Just clean it. Another situation is caused by the deformation of the wiper arm. It is necessary to check whether the lower plane of the wiper arm is in full contact. If there is a certain angle, it means that the wiper arm is deformed. You can use a wrench to adjust the angle of the wiper arm. Wrap the wiper arm with a thick towel to prevent the wrench from damaging the patent leather of the wiper arm.
1. Foreign matter on the wiper If there is a foreign matter between the wiper blade and the windshield, it will not only make a noise when scraping the glass, but also have a great impact on the wiping effect, and there will be certain safety hazards. Therefore, when passing a place with poor road conditions, it is recommended to check the wiper for foreign matter, and if there is, clean it up as soon as possible.
2. The quality of the wiper wiper The quality of the wiper blade is not good, the rubber component inside is often not very resistant, and the phenomenon of hardening (rough) is easy to appear under long-term sun exposure, so it is natural under working conditions. There will be noise. At this time, it only needs to be smoothed with sanding paper.
3. Wiper angle In addition to the above factors, the angle of the wiper is also one of the reasons, because the wrong angle will cause the wiper blade to jump on the windshield, causing abnormal noise. At this time, the owner only needs to adjust the angle by himself. Of course, the pressing force of the wiper should not be too large, otherwise it will aggravate the wear of the glass.
