What is the reason for the front wiper not spraying water?
2 Answers
The reasons why the front wiper does not spray water: 1. The wiper nozzle is clogged or the pipeline is detached. It is recommended to check the spray nozzle; 2. If it is not a problem with the spray nozzle, the fuse is damaged and needs to be replaced. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It adopts a DC permanent magnet motor, and the wiper motor installed on the front windshield is integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives the four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion through the four-bar linkage mechanism.
During my driving days, I often encountered situations where the front windshield wipers wouldn't spray water, usually caused by minor issues. For example, the reservoir might be empty—I forgot to refill it, or during long trips, evaporation is faster, and adding some washer fluid would solve it. Sometimes, the nozzles get clogged with dust; gently clearing them with a fine needle or toothpick works, but avoid using too much force to prevent damage. Winter is more troublesome when the water freezes and won't spray—I switch to antifreeze washer fluid as a precaution. Occasionally, the washer pump might be faulty (no humming sound when activated), or a fuse could be blown, requiring a check and replacement of the corresponding fuse in the fuse box. Wiring aging is also common, and delayed action during rainy days with poor visibility can be dangerous. Developing a habit of checking the reservoir level before driving saves a lot of hassle. While windshield wipers not spraying water isn't a complex issue, neglecting it compromises safety—regular maintenance is the wisest approach.
