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.
That time when my wipers suddenly stopped working in the rain, the windshield was completely blurred and it scared me. It was probably a stuck switch or dried-out rubber blades. Try turning off the engine and restarting it once to see. If that doesn't solve it, spending a bit to replace the part is super easy. It's quite handy to keep an old spare part in the car for emergencies, and doing a simple test before driving in the rain can help avoid trouble.
Wiper malfunctions typically indicate a non-functioning motor or jammed gears, possibly due to damp wiring causing a short circuit. Pay attention if you hear unusual noises or notice slow movement—electronic components are vulnerable to water, especially after car washes. Attempting DIY repairs risks electric shock or further damage; it's safer to have professionals inspect with proper equipment. Avoid driving in the rain to prevent hazards.
