Wiper blade chattering can be caused by: 1. Vibration due to issues with the wiper blade itself: Wiper blades are made of rubber and can harden or deteriorate over time, especially in winter. The solution is to replace the wiper blades with new ones. 2. Vibration caused by the wiper motor: If the motor lacks sufficient power, it may indicate the end of its lifespan. It is recommended to have a detailed inspection at a professional repair shop. 3. Foreign objects between the wiper blade and windshield causing vibration: When the wiper is activated, a sharp friction noise may occur between the blade and windshield. Check and clean any debris from the wiper blade or underneath it. 4. Wear and tear in the wiper linkage bushing causing vibration: Over time, the wiper linkage mechanism can age, the spring tension in the wiper arm may weaken, and the bushing can wear out or even detach. Inspect the wiper arm and linkage bushing for wear.

What is the reason for no response in headlight left-right adjustment?

No response in headlight left-right adjustment is due to the malfunction of the internal adjustment motor in the headlight, and replacing the motor can solve the issue. Below are specific details about headlight adjustment: Precautions: It should be noted that the width of the headlights is generally preset at the factory, and self-adjustment is not recommended. If there is any deviation, minor adjustments can be made. During adjustment, the right headlight beam can be slightly adjusted to the right, which can provide better visibility of the right side of the road during low-visibility conditions such as rain or fog. However, it is more advisable to have a professional adjustment done at a 4S shop or repair shop. Adjustment Method: Park the car 10 meters away from a wall, measure the distance from the car's low beam to the central axis, the distance from the high beam to the central axis, and the distance from the low beam to the ground. Then move to the wall and mark the corresponding points on the wall. Next, observe whether the headlight beams are offset left or right or too high or low. If the center of the headlight beam does not align with the marked points, it indicates an offset. This can be adjusted by rotating the headlight width adjustment knob to align the center of the headlight beam with the marked points on the wall.
