What is the reason for the windshield washer fluid not spraying but the wipers moving?
3 Answers
Generally speaking, if the windshield washer fluid does not spray but the wipers can move, it may be due to the windshield washer fluid level being too low or the spray nozzle being blocked by dust. Relevant information about windshield washer fluid is as follows: Introduction: Commonly known as automotive windshield cleaning fluid. It is a consumable in automotive use. High-quality automotive windshield washer fluid is mainly composed of water, alcohol, glycol, etc. Automotive windshield washer fluid is commonly known as glass water. Functions: Cleaning performance: Windshield washer fluid usually has functions such as wetting, penetrating, and solubilizing, thereby achieving the effect of cleaning and removing dirt. Antifreeze performance: The presence of alcohol and glycol can significantly lower the freezing point of the liquid, thus providing antifreeze effects and quickly dissolving frost.
The issue of windshield washer fluid not spraying while the wipers move is quite common. I suspect it's mostly a problem with the washer system. The fact that the wipers work normally indicates that the wiper mechanism is basically functioning, and the issue lies solely with the water spray. Possible causes: First, check if the windshield washer fluid reservoir is empty—sometimes there's simply no water to spray. Next, the nozzles might be clogged; dust or insects accumulating at the spray holes can block the water flow. There could also be a fault with the water pump or hoses, such as a broken pump or loose connections, or aged/cracked hoses leaking. In winter, washer fluid freezing can also prevent spraying, so it's best to use an antifreeze type. For safety, if the windshield is too dirty to see the road clearly, it's advisable to stop and address the issue first. If you can't determine the water level yourself, and both the pump and nozzles seem fine, it's best to visit a professional shop—don't delay to avoid accidents. Regularly refilling the fluid and checking the nozzles can prevent such issues.
I've encountered this issue before - the washer fluid won't come out but the wipers work fine, which is quite annoying. The key point is the washer system failure. Possible causes include clogged nozzles (I once had bird droppings blocking the spray holes, fixed by poking with a needle), or pump problems: aging or burnt-out motor (you'll notice no sound from the pump when operating wipers), or leaks/kinks in hoses interrupting flow. Don't forget to check fuses - a blown fuse will stop the pump. For DIY troubleshooting: first refill washer fluid, then check for loose pump connections; replacement may be needed if these don't work. Safety reminder: never attempt repairs while driving, pull over safely. Regular nozzle cleaning and using qualified washer fluid can prevent such issues.
