Why doesn't the newly added windshield washer fluid come out?
4 Answers
Just added windshield washer fluid not coming out is due to internal blockage, which requires timely cleaning or replacement of the delivery hose. Below are specific details about the windshield washer fluid: 1. Pay attention to temperature: Before adding windshield washer fluid, it's necessary to understand the local climate, mainly the temperature. If it's below zero degrees, choose a windshield washer fluid with a low freezing point to ensure it doesn't freeze in the car after being added. 2. Water cannot replace windshield washer fluid: Water should not be used as a substitute for windshield washer fluid in cars, mainly because it freezes at 0 degrees in winter, and tap water contains many impurities, which can easily cause aging of components.
I've been driving for several years and encountered this issue before. When the windshield washer fluid doesn't spray after refilling, the most common cause is clogged nozzles. Dust and dirt can easily accumulate over time, so remember to clean the spray holes during car washes. Another possibility is a pump problem, such as a stuck motor or blown fuse. Sometimes air gets trapped when adding new fluid, causing insufficient pressure—try pressing the button a few more times to release the air. Also, if the reservoir cap isn't tightened properly, pressure can leak, preventing the fluid from spraying, so it's best to check the cap's seal. In cold weather, frozen fluid (especially non-antifreeze washer fluid) can cause this too—winter requires special formula. If none of these are the issue, it might be poor wiring contact or a faulty switch, requiring a multimeter test at a repair shop. Don't underestimate this—impaired visibility during rain is dangerous. I always remind myself to inspect the cleaning system during every maintenance check.
When I drive my kids to school, I often need to add windshield washer fluid. The most common reasons for it not spraying after refilling are: not aligning the filler port properly, insufficient fluid level in the reservoir, or a leaking hose, requiring me to reopen the cap and check. Another cause could be the nozzle being blocked by debris like leaves or small insects, which can be cleared by gently poking with a toothpick, but be careful not to apply too much force to avoid damage. Another possibility is pressing the button too quickly, causing the system to not respond immediately—just wait a few seconds and try again. In winter, low temperatures can cause the fluid to freeze, so switching to an antifreeze-type windshield washer fluid is the solution. A simple preventive measure is to regularly clean the front of the car to keep it tidy. I clean it every month, which ensures safety and saves trouble.
When I DIY car repairs, the windshield washer fluid not spraying is usually due to a malfunction in the washer system, such as a faulty pump, which is responsible for pushing the liquid. If it's stuck or worn out, it needs to be replaced. Alternatively, a cracked or bent tube can cause insufficient pressure, so check along the tube for leaks or kinks. If the nozzle angle is off, it may spray incorrectly or not at all—simply adjust it to the correct position. Air blockages are common right after refilling the fluid, requiring multiple switch operations to purge the air. If a fuse is blown, locate the corresponding one in the car's fuse box and replace it. Don't forget to use the appropriate windshield washer fluid to avoid corroding components, and regular maintenance can extend the system's lifespan.
