Why does the windshield wiper move but not spray water?

[OEloise]

When the windshield wiper moves but fails to spray washer fluid, there are several possible reasons for the lack of water output: low fluid level, clogged nozzle, frozen tubing, damaged motor, or blocked pipeline. The windshield wiper is a device designed to remove raindrops and dust attached to the vehicle's windshield, improving driver visibility and enhancing driving safety. Precautions for daily wiper usage: 1. Regular cleaning: Temperature changes or debris like sand and dust can shorten the lifespan of wiper blades. Frequently clean dirt from the windshield and wiper blades, especially after rain, to reduce unnecessary wear and extend the blade's service life. 2. Avoid dry wiping: The primary condition for using wipers is to operate them when there is rainwater. Never use them dry, as this can damage the rubber blades and the wiper motor. 3. Moderate use: At the beginning of rainfall, if the amount of rain is insufficient to obstruct the driver's view, it is advisable not to use the wipers.

Last time I was driving, I noticed the wipers were moving but no water was spraying, which really confused me. My first thought was that the windshield washer fluid was empty. I popped the hood and sure enough, the reservoir was bone dry, so I quickly filled it up with fresh fluid to test. If that still doesn't work, the spray nozzles might be clogged with dust or grime—just gently poke a fine needle in to clear them. Don't panic if the water's frozen in winter; add some antifreeze or wait for warmer weather to thaw it. I also checked the fuse: locate the headlight or wiper label in the fuse box under the driver's seat, and replace it if blown. A faulty motor might hum or stay silent, in which case you'll need a repair shop to swap the part. Remember, DIY saves time, but safety comes first—if unsure, seek help promptly. Otherwise, a dirty windshield in rain could lead to accidents.

I've driven quite a few cars, and when the wipers move but don't spray water, the most common issues are either the windshield washer fluid running out or the spray nozzles getting clogged. Fixing it yourself is quite simple: first, check the reservoir and fill it with water, then try the switch. If that doesn't work, use a soft brush to clean the nozzle holes. Another possibility is a cracked pipe leaking water—feel the pipe wall to see if it's wet. Or, the water pump motor might be aging and humming without working properly; if the sound is abnormal, it's time to replace it, which isn't costly. Don’t forget to check the fuse box—find the wiper-related position and test for continuity. Regularly maintain and clean the system to prevent sediment buildup. Don’t delay too long, because poor spray performance is especially dangerous in dusty areas, as blurred vision can easily lead to accidents. Turning a small issue into a big one isn’t worth it.

The wipers moving indicates the mechanical parts are functioning normally, while no water spray suggests a fault in the spraying system, akin to a water pipe being cut off. The simplest solution is usually clogged nozzles blocked by dirt; cleaning can restore function. If the water pump motor is broken, there will be no sound of operation, requiring direct replacement. Detached or cracked hoses will leak, leaving traces under the car. Simply refill if the windshield washer fluid is insufficient. A blown fuse interrupts the circuit; refer to the manual to locate and replace it. The system operates independently and does not affect the wipers' movement, but the lack of function can compromise safety in rainy conditions.
