What to Do When Windshield Washer Fluid Has Low Pressure and Doesn't Spray High?
2 Answers
If the windshield washer fluid sprays too low with insufficient pressure, you can make the following adjustments: The low spray can be corrected by adjusting the nozzle angle using a tool. Before making adjustments, first observe the range where the water stream reaches, then use a prepared tool to fine-tune the spray nozzle. The adjustment tool can be a needle or any other item that facilitates angle adjustment. Adjust it to a suitable position so that the washer fluid sprays onto the center of the windshield, allowing the fluid to function effectively. Below is an introduction to the ideal washer fluid spray position: 1. When the car's washer fluid sprays too high: The fluid may be carried by airflow to the roof or even the vehicle behind, not only wasting the washer fluid but also causing inconvenience. 2. When the washer fluid sprays too low: It may fail to clean the driver's line of sight area, resulting in poor spray performance and preventing the washer fluid from functioning fully. Windshield washer fluid not only cleans the glass but also forms a protective film to prevent fog droplets from forming on the glass while improving its frost resistance.
I've also encountered the issue of low pressure when the windshield washer fluid doesn't spray high enough while driving. That time, during a rainy day, I suddenly noticed the nozzles were dispensing very little water and couldn't spray high, making it almost impossible to see the road clearly. After pulling over, I checked and found that the nozzle holes were clogged with dust and debris. I used a fine needle to gently clean out the holes, and the problem was immediately resolved. It's also important to check if there's enough washer fluid in the reservoir. If it's empty or if tap water was used, mineral deposits could clog the system or affect the pressure. The fuse box should also be inspected—if the pump isn't making any humming noise, the fuse might be blown or the wiring could be loose. I recommend using dedicated washer fluid every few months instead of plain water to avoid these issues. In cold weather, use antifreeze to prevent freezing and system blockages. Remember these small steps—fixing it yourself can save time, effort, and money.
