What does a faulty windshield wiper mean?

Wiper failure may be caused by a blown fuse; a faulty wiper switch; a burnt-out wiper motor; or a defective wiper interval relay. Here are some precautions for using wipers: 1. Maintain cleanliness: When there are streak marks on the glass surface, the wiper blade may be dirty. You can sprinkle alcohol on a towel and wipe the surface of the wiper blade. Cleaning it once a month can improve the wiper's performance. 2. Check the rubber: If the wiper makes unusual noises while operating, the rubber blade may be aging or cracked. If the wear is not severe, you can use sandpaper to smooth out rough spots on the surface. 3. Avoid sunlight: Park the car in a shady place out of direct sunlight, such as a garage. Summer is particularly harsh on cars. Wiper blades are rubber products and will age faster in the sun. 4. Refill fluid: Do not simply add water to the windshield washer fluid reservoir, as this is detrimental to the maintenance of the windshield and wiper blades in the long run. To ensure the longevity of the components, always use proper windshield washer fluid. Refill the washer fluid promptly to be prepared for unexpected needs.
The windshield wiper malfunction means the wipers won't move or can't clean rainwater properly, possibly due to a burnt-out motor, aged rubber blades, or wiring issues. Having driven for over a decade, I've seen many such cases - it's particularly dangerous in rainy weather with blurred vision, easily leading to accidents. First check the fuse box to see if any are broken; if that doesn't work, don't attempt random disassembly but go to a repair shop for professional service. Regularly replacing the rubber blades can prevent malfunctions - don't wait until rainy days to regret not doing so.
