What Causes the Windshield Wiper Not to Spray Water?
2 Answers
Common reasons for windshield wipers not spraying water include clogged nozzles or hoses; motor, water pump, fuse, or wiring failures; or running out of windshield washer fluid. If the nozzles or hoses are clogged, you can try unclogging them yourself. If the washer fluid is empty, simply refill it. For other issues, visit a 4S shop for inspection and repair. Below are solutions for windshield wipers not spraying water: 1. First, determine whether the issue is on one side or both sides. If only one side is affected, it is usually due to a clogged nozzle on that side. There are two solutions: (1) Use a sewing needle, pin, or very thin wire to poke through the clog. (2) Spray out the remaining washer fluid, then use an air gun to blow through the clogged nozzle. 2. If both sides have issues, it may be due to low washer fluid, hose problems, clogged filters, or motor issues. Follow these steps: (1) First, check if the washer fluid is low and refill it if necessary. (2) Inspect the hose for damage or loose connections. (3) Check the motor and wiring. Have someone press the spray button while you listen near the engine bay for the motor sound. If the sound is weak, the motor may be faulty. If there is no sound and the wiring is fine, the motor itself is likely the issue. (4) If the motor is the problem, first check if the filter is clogged. A clogged filter can be cleaned—for example, by disconnecting the hose from the nozzle, opening the washer fluid reservoir, and using an air gun to blow through the hose, forcing debris out of the filter. For other issues, consult a professional at a 4S shop.
I've encountered the issue of windshield wipers not spraying water many times. The most likely cause is that the windshield washer fluid has run out. It's important to refill it with the dedicated cleaning solution in time, and avoid using tap water to prevent clogging the nozzles. Additionally, the nozzle holes can easily get blocked by mud or dirt. Using a fine needle to gently clean them usually solves the problem, but be careful not to apply too much force to avoid damage. A broken pump is another common reason—once it fails, it can't pressurize the water for spraying. Replacing it costs around a hundred bucks, which isn't too expensive. A blown fuse could also be the culprit; you can usually find the corresponding fuse in the engine compartment's fuse box. Pull it out to check, and if it's blackened, just replace it. Loose wiring or a cracked pipe might also be the issue, especially after long drives where bumps could cause damage. Regular maintenance is key, especially during seasonal changes, to clean the system and prevent freezing or jamming, ensuring safe driving visibility.
