How to Fix Wiper Blade Jumping and Noises?
1 Answers
The root cause of wiper blade noise is the improper installation of the blade support frame (not parallel to the windshield). It is necessary to determine whether the noise occurs during the upward or downward movement of the blade. Below are specific solutions for wiper blade noise: 1. Noise during upward movement: This indicates that the wiper frame is twisted upward. Stop the wiper in the middle position (pull the wiper control lever toward the steering wheel after turning off the engine), then gently lift it. Wrap the frame with a cloth or soft material, and use a wrench or pliers to twist the wrapped part downward a few times. After resetting, test the wiper. If the noise decreases, repeat the process until the noise is eliminated. 2. Noise during downward movement: This indicates that the wiper frame is twisted downward. Stop the wiper in the middle position and lift it. Wrap the frame with a cloth or soft material, and use a wrench or pliers to twist the wrapped part upward a few times. After resetting, test the wiper. If the noise decreases, repeat the process until the noise is eliminated. 3. Noise during both upward and downward movements: If a single wiper blade produces noise during both movements, the blade needs to be replaced.
