What is the reason for the windshield washer fluid not spraying but the wipers still working?
2 Answers
The reasons why the windshield washer fluid does not spray but the wipers still work are: 1. The washer fluid level is too low and does not reach the standard height; 2. The washer fluid nozzle is blocked by dust; 3. The washer fluid reservoir or pipeline is frozen; 4. The fuse is blown or the motor is damaged; 5. There is high-pressure gas inside the washer fluid reservoir; 6. The washer fluid pipeline is blocked by impurities. Windshield washer fluid is the common name for automotive windshield cleaning fluid, which is a consumable item in vehicle 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 helps maintain excellent transparency of the front windshield and also features quick snow and ice melting, anti-glare, and anti-fogging properties, playing a significant role in improving driving safety.
Recently encountered a situation where the windshield washer fluid won't spray but the wipers still work. I've experienced this several times myself, and it seems quite common. Possible causes include an empty reservoir, clogged nozzles, or a faulty pump. First, check the reservoir: pop the hood and inspect the washer fluid tank. If the level is low, try filling it up. Nozzle clogs are also very common, especially during dusty seasons on older cars. Use a fine needle or toothpick to gently poke the nozzle holes to see if water flows out. If adding fluid doesn't help, listen for a humming sound from the pump. No sound might indicate a motor failure or blown fuse - in this case, check the fuse box for the corresponding fuse. In winter, hoses can freeze, while in summer, rapid evaporation affects performance. I recommend troubleshooting yourself before rushing to a mechanic to save money. However, if the problem persists, don't ignore it. Driving with wipers but no washer fluid leads to blurred vision and increased accident risk - safety comes first.
