How to Determine If Wiper Blades Need Replacement
2 Answers
Here are methods to determine if wiper blades need replacement: 1. If the wiper blades have been used for one or even two years, it is best to replace them immediately. After one year of use, the rubber strips on the wiper blades will begin to deteriorate, significantly reducing their effectiveness. 2. When using the wipers during rain, observe carefully. If the wipers effectively clear rainwater from the windshield without leaving the glass blurry afterward, they do not need replacement. However, if they leave streaks or the glass remains unclear, replacement is necessary. 3. When the vehicle is not in use, lift the wiper blades and inspect the rubber strips. If the strips are intact and undamaged, they are still usable. If cracks are visible, the blades should be replaced. 4. If the wipers produce unusual noises, such as squeaking or screeching sounds after wiping the glass, these noises indicate that the wiper blades need replacement. 5. While using the wipers, observe from inside the cabin. If six streaks or marks are left on the windshield after wiping, the wiper blades should be replaced. 6. Additionally, if the wipers exhibit shaking or jumping movements during operation, this is a sign that they need to be replaced.
Last time I noticed the wipers weren't cleaning properly due to aging rubber blades. At first, there were just a few water streaks left on the windshield, which seriously affected visibility during rainy drives. Upon closer inspection, I found the edges of the rubber blades were cracked and felt stiff to the touch. Later during rain, I also noticed the wipers would skip and the entire windshield would shake. Remember these key points: no water streaks should remain after wiping, wiper movement should be smooth without unusual noises, and the rubber blades must not become stiff or cracked. Especially before the rainy season, it's crucial to check them - if you see fine cracks along the edges, it's time to replace them. Experienced drivers know that waiting until they completely fail to clean is too dangerous.
