What should I do if the wiper makes an unusual noise and does not wipe cleanly? How to solve the problem of wiper skipping?

Cars are consumables, and windshield wipers are one of the more obvious consumable parts. If the wipers have abnormal response, it must be a quality problem of the wipers. It is recommended to check and clean them carefully and replace them with good quality wipers in time, otherwise the glass will be scratched over time.

What should I do if the wiper makes unusual noises and does not wipe cleanly?

This problem generally does not occur in new cars, so the situation where the wiper blades do not wipe cleanly may be due to aging of the wiper blades, or the replacement of wiper blades that do not meet quality standards. Thirdly, the angle between the wiper arm and the glass may not be suitable, resulting in poor wiper cleaning and abnormal noise, but this kind of thing generally does not happen.

The best way to solve the problem of poor wiping caused by not replacing the wiper blades after using a new car for a long time is to replace them with new ones. However, many friends feel that the new wiper blades are not as good as the old ones. That's right, because you replaced a wiper blade that just looks like a wiper blade.

How to solve the problem of wiper jumping

①. The entire wiper bracket can be replaced 180 degrees (some brackets can);

②. You can pull the wiper strip out of the bracket, swap the two ends and then insert it into the bracket (the bracket does not move, and the strip is swapped 180 degrees);

③. Adjust the pressure of the wiper arm on the glass (the pressure of the swing arm spring). Just bend the swing arm by hand. (If the glass is not completely wiped, it is also a pressure problem)

④. Make sure you don’t use windshield repellent

Why can't the new wiper blades clean well?

If the wiper blades still vibrate, make strange noises, or have poor cleaning effects after being replaced with new ones, then the problem should be with the wiper arms of the original car. Or the angle is wrong, resulting in uneven downforce, or the wiper arm spring metal fatigue is serious, resulting in too much deterioration of downforce; the solution is to bend it to see if it can be solved, and if it still doesn't work, then consider replacing the spring. As for the buzzing sound, it is mostly the sound of the wiper motor or wiper blade rubbing against the windshield, and silent wipers cannot achieve zero decibels, for reference only.

Use 2000-grit sandpaper coated with coarse wax to evenly grind the wiper rubber strip contact surface vertically (the rubber strip contact surface has thickness and cannot be ground into a knife edge). The best way to protect the wiper is to lift the wiper before using the car and clean the dust and foreign matter on the rubber strip and windshield.
