What is the reason for the abnormal noise in the first gear relay of the Bora wiper?
2 Answers
The reasons for the abnormal noise in the first gear relay of the wiper are as follows: 1. Foreign objects between the wiper blade and the windshield. When the wiper is turned on, there will be a sharp abnormal noise caused by the friction between the wiper blade and the front windshield. The owner can check and clean the wiper blade or the area below the wiper to ensure the cleanliness of the wiper blade. 2. Problems with the wiper blade itself. The wiper blade is a rubber product, and after a period of use, it will age and harden, which is more obvious in winter. 3. Friction in the wiper linkage bushing. With the aging of the car, the wiper linkage mechanism will age, the elasticity of the wiper arm spring will decrease, and the bushing will also wear out, even leading to detachment. Additional information: Wiper: Also known as a windscreen wiper, it is a device used to remove raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and increase driving safety.
I've been driving a Bora for ten years, and the relay often buzzes when the wipers are on the first speed. It's mostly caused by the aging relay's contact points bouncing, which creates noise. It's usually fine, but it's annoying on rainy days and may cause the wipers to fail, making it hard to see the road. The relay is located in the fuse box under the hood. Over time, dust buildup or coil wear can cause voltage instability, leading to the buzzing sound. Last time, I tried disassembling and cleaning the contacts, but if that doesn't help, it's best to replace the relay. They're not expensive, just a few dozen bucks each. For safety, it's better to have it done at a professional shop. Don't ignore the buzzing sound while driving—if something goes wrong on a rainy day, it might be too late.
