What is the reason for the windshield washer fluid not spraying but the wipers still working?
2 Answers
Windshield washer fluid not spraying but the wipers still working is because the windshield washer fluid level is too low or the spray nozzle is clogged with dust. Specific reasons: The windshield washer fluid level is too low and does not meet the standard height, the windshield washer spray nozzle is clogged with dust, the windshield washer reservoir or pipeline is frozen, the fuse is blown, or the motor is damaged, there is high-pressure gas inside the windshield washer reservoir, or the windshield washer pipeline is clogged with impurities. Meaning of windshield washer fluid: Windshield washer fluid is the common name for automotive windshield cleaning fluid, which is a consumable in car use. High-quality automotive windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. During nighttime driving, windshield washer fluid can keep the front windshield in a highly transparent state and also has properties such as rapid snow and ice melting, anti-glare, and anti-fogging, playing a significant role in improving driving safety.
The windshield washer fluid won't spray but the wipers work - this is a common issue I've encountered with used cars. Several aspects need troubleshooting. The most common cause is clogged washer nozzles, like when I used tap water for car wash last time and impurities blocked the spray holes. Another possibility is empty or nearly empty washer fluid reservoir - especially in summer when evaporation is fast, check the fluid level as low level prevents the pump from drawing water. A faulty water pump can also cause this - working wipers indicate the electrical circuit is fine, but separate washer pump circuit issues like short circuits or aged wiring may be the culprit. Cracked or leaking hoses could be another reason, as pipe fractures lead to pressure loss. For inspection, first clean nozzle holes with a needle tip. If that doesn't work, check the pump fuse or try new washer fluid. For safety, don't attempt repairs while driving - pull over first. Regular washer system maintenance like avoiding hard water for car washes can prevent such issues.
