Troubleshooting Abnormal Noise and Jumping Issues of Wiper Blades
Nowadays, with the development of the automobile industry, the wiper blade technology is very mature, but this essential device when driving in rainy days is not born with it.
From the birth of the first modern car in 1885 to the beginning of the twentieth century, there was no such device as wiper blades on the car. Drivers had to open the windows when driving in rainy days. have an accident.
In our daily use, there are often wiper blades that are not clean, skipping brushes, and abnormal noises .
Wiper blades are an essential component of a vehicle’s safety system, ensuring clear visibility during adverse weather conditions. However, drivers often encounter issues such as abnormal noise and jumping movements from their wiper blades.
In this article, we will explore the potential causes for these problems and provide practical solutions to address them effectively.
Section 1: Understanding the Causes
1. Misalignment
Misalignment occurs when the wiper blade is not correctly positioned on the windshield. This can lead to uneven contact with the glass surface, resulting in erratic movements and unusual noises.
2. Worn-out Blades
Over time, wiper blades can deteriorate due to exposure to the elements and constant friction. When the rubber component becomes damaged or worn out, it can cause irregular movements and generate unwarranted sounds.
3. Contamination
Accumulation of dirt, debris, or ice on the wiper blade’s surface can interfere with its smooth operation. This may cause the blade to skip or jump across the windshield, producing unexpected noise.
4. Loose or Damaged Components
Loose or damaged components within the wiper assembly, such as the wiper arm or linkage, can lead to instability and jerky movements. Consequently, this can result in audible disturbances during operation.
Section 2: Troubleshooting Techniques
1. Realignment
To fix misalignment issues, start by lifting the wiper arm away from the windshield and examining the blade’s position.
Ensure that it is parallel to the bottom edge of the windshield, making proper contact throughout its length. Adjust the blade as necessary, ensuring a secure fit to prevent unnecessary noise and jumping.
2. Blade Replacement
If the wiper blades show signs of wear or damage, it is advisable to replace them. Choose high-quality blades that are compatible with your vehicle’s make and model. Follow the manufacturer’s instructions for installation, ensuring a snug fit. This can significantly reduce noise and improve performance.
3. Cleaning
Regularly clean the wiper blades with a mild detergent solution or windshield washer fluid. Gently wipe the rubber component to remove any dirt, grime, or debris. In colder climates, ensure that ice does not accumulate on the blades by defrosting the windshield before activating the wipers.
4. Inspection and Repairs
Inspect the wiper assembly components for any signs of looseness or damage. Tighten any loose bolts or nuts and replace damaged parts promptly. Seek professional assistance if you are unsure about handling repairs yourself.
Determine the source of abnormal noise:
1. Wiper blade problem
Wiper blades are made of rubber, and they will age and harden after a period of use. This is more obvious in winter. Apart from making abnormal noises, they cannot scrape cleanly. The simplest and most effective solution is to directly replace the wiper blades with new ones. .
Wiper blades are generally recommended to be replaced every 6 to 12 months.
2. There are foreign objects between the wiper blades and the windshield
When the wiper blade is turned on, there will be a sharp friction sound between the wiper blade and the front windshield. The owner can check and clean up the foreign matter on the wiper blade or the bottom of the wiper to ensure that there is no foreign matter between the wiper blade and the windshield that will affect the cleaning.
3. The sound made by the friction of the wiper blade connecting rod bushing
As the car ages, the wiper linkage mechanism will age, the spring elasticity of the wiper arm will decrease, and the bushing will wear out or even fall off. At this time, it is necessary to check the wiper arm or wiper blade linkage bushing.
4. Abnormal noise from the wiper motor
If it is found that the wiper motor is making abnormal noise, it is likely that the motor needs to be replaced. At this time, you should go to a professional repair shop for a more detailed inspection.
How to solve the jumping brush ?
①. The whole bracket of the wiper can be replaced by 180 degrees (some brackets can);
②. The wiper rubber can be pulled out from the bracket and the two ends are exchanged and then inserted into the bracket (the bracket does not move, and the leather strip is replaced by 180 degrees);
③. To 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 scraped, it is also a pressure problem)
④. The angle of the wiper swing arm is wrong, which causes the angle of the wiper blade and the windshield to change when it contacts.
The main reason is that the wiper blade is not as vertical as possible to the glass. Just use the pliers to clamp the front end of the wiper arm (the hook hooked to the wiper) and twist it, the wiper will twist it counterclockwise when it scrapes upwards, and twist it clockwise when it scrapes back.
Keep the wiper strip vertical to the glass surface until it stops jumping.
However, it is also possible that no matter how you adjust it, there is no way to solve it. At this time, it may be caused by the aging of the wiper blades, and the wiper blades need to be replaced.
So what should you pay attention to when using wipers every day ?
①. Add glass water regularly, do not use tap water instead. The degreasing ability and volatility of glass cleaning fluid are better than tap water;
②. Be sure to use the wiper blade when there is water on the glass surface to avoid dry scraping. Wiper blade rubber is made of rubber material, dry scraping will damage the rubber;
③.Clean the attachments on the wiper blade rubber and glass surface in time.
Because these attachments may damage the rubber. When cleaning, please use a soft cloth dipped in glass cleaning fluid to scrub gently to avoid damaging the rubber with excessive force;
④. When the vehicle is parked for a long time or parked in ice and snow weather, please raise the wiper arm;
⑤. When using the car in winter, if the windshield has obvious snow or ice, it is recommended to wipe off the snow or ice particles and then use the wiper blade to avoid the wiper from swinging on the snow surface and causing deformation;
⑥. If you can use slow gear to scrape, you don’t need to use fast gear to scrape.
The faster you scrape, the more you use it, the more times you rub it, and the service life of the wiper blade will be reduced accordingly.
Conclusion
By understanding the causes behind abnormal noise and jumping issues of wiper blades and following the troubleshooting techniques provided, drivers can rectify these problems and ensure smooth and quiet operation.
Regular maintenance and prompt repairs will not only enhance driving safety but also extend the lifespan of wiper blades. Remember, a well-functioning wiper blade system is crucial for optimal visibility, especially during inclement weather conditions.
