The reasons for the squeaking sound of windshield wipers on the glass may include the following points: 1. There may be debris or foreign objects in the grooves on both sides of the wiper blade. 2. The car glass may be dirty. 3. The wiper may be deformed or aged. The solutions are as follows: 1. First, check if there are any foreign objects between the wiper blade and the glass. If there are, remove them. Then, inspect the rubber part of the wiper blade for hardening, gaps, cracks, or tears. If any are found, replace the wiper blade. 2. If there are only burrs, you can lightly sand them twice with 1000-grit sandpaper and try again. This ensures the wiper maintains the correct angle with the glass without deforming. Therefore, you may need to adjust the angle of the wiper first. 3. If the angle between the wiper blade and the glass is incorrect, gently lift the wiper to see if the part in contact with the glass is vertical. If not, slightly adjust the wiper arm. Solution: When the wiper is dry, move it to the maintenance position, lift the problematic wiper, and twist the wiper blade left and right a few times. This usually squeezes out any sand particles in the grooves. 4. If this doesn’t work, or if the wiper is wet, use a small flat-head screwdriver to run along the grooves on both sides of the wiper blade from start to finish. Alternatively, if there is a loose spot on the wiper that clamps the rubber blade, use needle-nose pliers to tighten the gaps at each joint and the rubber blade clamping point.
