How to Check the Condition of Car Wiper Blades Regularly?

[Alex]

Here are the methods to check the condition of car wiper blades: 1. Lift the wiper blade and run your fingers along the cleaned blade. If the blade shows signs of aging, hardening, or cracking, it is unqualified and needs immediate replacement. 2. Set the wiper switch to different speed positions and check if the wiper maintains a consistent speed at each setting. 3. If the wiper blade exhibits uneven side-to-side movement, noise, abnormal jumping, incomplete contact with the windshield, poor cleaning performance, water film, fine streaks, or residue, it indicates damage or unqualified condition. 4. You can also assess the wiper blade's condition by listening for unusual sounds. If the wiper motor makes abnormal noises and fails to rotate, it suggests rusting or jamming in the mechanical transmission parts, indicating an unqualified wiper blade. In such cases, immediately turn off the wiper switch to prevent motor burnout.
