Why is the windshield washer nozzle spraying weakly and not reaching high?
2 Answers
The reason why the windshield washer nozzle sprays weakly and does not reach high is that the nozzle is clogged or the motor inlet in the water tank is blocked, or the motor may be damaged. Here is some extended information: 1. Columnar nozzle: Since the columnar nozzle is set in the external spraying device and is visible to the naked eye, high-pressure water gun washing and scale residue during car washing can cause slight changes in the nozzle angle. This may likely cause the spraying angle to deviate from the correct trajectory, which is why some vehicles spray water off-target. 2. Mist nozzle: Unlike the columnar nozzle, the mist nozzle evenly sprays water droplets or mist, and the spraying area is larger than that of the columnar nozzle. The mist nozzle is preset before the vehicle leaves the factory, and the internal shower head disperses the water column. Therefore, if there is a problem, it cannot be adjusted by oneself and must be repaired at a professional repair shop.
I often encounter the frustration of the windshield washer fluid not spraying high enough. At first, I thought the reservoir was empty, but it turned out that the small holes in the nozzles were completely clogged with dust or scale, making the spray as weak as dripping water. During my own inspection, I found that the high temperatures in summer and the dust kicked up on the road easily block these holes, especially when using tap water instead of dedicated washer fluid for a long time, as mineral buildup occurs faster. Later, I learned to gently clear the spray holes with a fine needle, and the water flow immediately regained its strength. Another common issue is a broken or aged pump in the reservoir, which leads to insufficient pressure and weak spray. In such cases, it's necessary to check if the pump is making normal operating sounds. Additionally, cracked pipes or loose connections can cause leaks, affecting the spray force. Before each seasonal change, I perform a small maintenance routine, such as clearing the holes and checking the hoses, ensuring clearer and safer visibility while driving in winter. Don’t underestimate this problem—weak spray can reduce cleaning effectiveness during rain or snow, increasing driving risks.
