What is the reason for the new wiper not adhering to the windshield in the middle?
2 Answers
The reason why the middle part of the wiper does not adhere tightly to the windshield is due to deformation of the wiper arm. Relevant information about the wiper is as follows: 1. Introduction: The wiper, also known as a windscreen wiper or windshield wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, thereby improving the driver's visibility and enhancing driving safety. 2. Usage: On rainy days, when raindrops fall on the car window glass, the view ahead is quickly obstructed, making vehicles, pedestrians, and scenery appear blurry. At this time, turning on the wiper will restore clear vision ahead.
I just replaced my new wiper blades, but the middle part wouldn't adhere to the windshield. After struggling for a while, I finally figured out the issue. This is quite common, mostly due to improper installation. You need to push the wiper blade onto the hook until you hear a 'click' sound to ensure it's locked in place. If there's no sound, the middle part tends to lift. The wiper arm might be bent—check if it's parallel to the curvature of the windshield. Oil or dirt on the glass can also affect adhesion, so clean it with glass cleaner before each replacement. The size must match your vehicle; blades that are too short or too wide won't distribute pressure evenly. I recommend taking your time during installation—don't rush to hit the road. Poor adhesion leads to ineffective wiping and reduced visibility, which is dangerous in the rain. I usually do some minor maintenance myself, saving quite a bit of money. Regularly replacing wiper blades is also crucial—don't wait for an accident to prioritize safety.
