What are the reasons for the windshield wipers not spraying water?
2 Answers
Windshield wipers not spraying water can be caused by: 1. Insufficient wiper fluid; 2. Incorrect wiper fluid selection; 3. Malfunction of the wiper spray motor; 4. Failure of the wiper spray piping or nozzles. Windshield wipers, also known as wiper blades, are devices used to wipe away raindrops and dust attached to the vehicle's windshield, thereby improving the driver's visibility and enhancing driving safety. High-quality wiper fluid can quickly remove stubborn stains, oil, and rain residue from the windshield and form a protective film to prevent the attachment of dust and oil, making the wiper blades glide more smoothly and cleanly, ensuring a clear and bright driving view.
As a car owner with over 10 years of driving experience, I can share that there are several common reasons why windshield wipers stop spraying water. The most frequent issue is an empty washer fluid reservoir or insufficient fluid – I often forget to refill it, especially during hot summers when the liquid evaporates quickly. Clogged spray nozzles are also a significant concern, as accumulated dust or tree sap can block the water flow; in such cases, you can use a needle or fine object to clean the nozzles. Another major problem is a malfunctioning washer fluid pump – if the pump fails, the water spray stops, often accompanied by the absence of the motor sound. Electrical issues like wiring faults or blown fuses are critical too, as interrupted current can cause system failure; if a fuse is blown, you'll need to locate and replace it in the car's fuse box. Additionally, leaking or frozen pipes (common in winter when they ice up) can prevent fluid transmission. Remember to regularly check the washer fluid level and maintain the spray system to avoid the embarrassment of poor visibility during heavy rain.
