Why is the car windshield washer spray weak?
2 Answers
Reasons for weak windshield washer spray in cars: 1. When there is insufficient windshield washer fluid, the internal pressure decreases, leading to weak spray. It is necessary to refill the windshield washer fluid in time; 2. If you usually use tap water or tap water mixed with dish soap or laundry detergent instead of windshield washer fluid, the spray nozzles may become clogged over time. In this case, you need to clean the spray nozzles and use windshield washer fluid; 3. If the pressure pump fails, the spray will be weak due to insufficient pressure. In this situation, you need to go to a 4S shop for repair. For the wiper system to work better, it is essential to have windshield washer fluid and wipers. Windshield washer fluid is specially designed cleaning water for wipers, with characteristics such as cleaning, antifreeze, lubrication, and anti-corrosion properties, ensuring better visibility while the car is in motion.
I usually enjoy tinkering with my car myself. The issue of weak windshield washer spray is quite common, and usually, the culprit is the nozzle being clogged with dust or debris. First, carefully clean it with a fine needle or toothpick. If that doesn't work, check if there's enough water in the washer fluid reservoir—if the level is too low, it won't be able to draw up enough fluid, so refill it and try again. The water pump might be the problem; insufficient motor power or a faulty motor can also cause this. If you don't hear a buzzing sound when you turn on the washer switch, don't delay. Also, check if the plastic tube is kinked or has cracks causing leaks, as these can lead to sluggish spray. Regular cleaning and maintenance of the nozzle can prevent this, especially since it's more likely to freeze and cause trouble in winter. Finally, it's best to have a professional shop do a thorough check—don't wait until you're caught off guard during a rainstorm. Safety first.
