Loud Noise After Replacing Wiper Blades

[EmeryLynn]

If there are still issues with unclean wiping and unusual noises after replacing the wiper blades, it is likely caused by a dirty windshield. When the vehicle is parked outdoors, dust and foreign objects such as resin can accumulate on the windshield, leading to ineffective wiping. In this case, it is necessary to clean the windshield. You can use a clay bar to remove dust and resin from the windshield. If there is a "clicking" noise coming from the lower part of the windshield, the gears inside the wiper motor should be checked for wear. Over time, gaps can develop in the internal gears of the wiper motor, causing the "clicking" noise during operation. In this case, the wiper motor needs to be replaced. Check if the wiper arm is deformed, which can cause the wiper blade to not fit tightly against the glass, resulting in unusual noises. If the wiper arm is found to be deformed, it should be replaced. The replacement cycle for wiper blades is generally once a year.
