What Causes the Windshield Wiper to Not Spray Water?

[DiDaniel]

Here are the reasons why the windshield wiper does not spray water: 1. Blocked spray nozzles: This is usually easy to identify. It is unlikely for both nozzles to be completely blocked at the same time or entirely clogged. The typical symptoms are reduced water flow or abnormal spray patterns. Determining whether the nozzles are blocked should be straightforward. 2. Pump overload: If the spray nozzles or water hose are blocked (e.g., due to frozen windshield washer fluid in winter), frequent activation of the washer spray can overload and damage the pump. 3. Blown fuse for the washer pump: If the water hose or spray nozzles are blocked, causing the pump to operate under excessive load, the fuse is most likely to fail first.

That time when I was driving in the rain and the windshield wipers weren't spraying water, I found the reservoir was empty. Always remember to keep a bottle of washer fluid in the car—adding it solved the problem immediately. Nozzle clogging is also a common issue, where dust accumulation prevents water flow; gently cleaning it with a fine needle can unclog it. In winter, the fluid might be frozen, so either switch to antifreeze washer fluid beforehand or pour hot water near the nozzle. Sometimes, the tubing or pump is faulty—if you don't hear the spraying sound, check for a short circuit in the wiring or a blown fuse, safety first. It's recommended to check the washer fluid level monthly and clean the nozzles to prevent clogging.

When it comes to the windshield washer not spraying, I have to mention pump failure or wiring issues. Last time I encountered this, I found the pump was jammed by debris or the motor was burnt out, often due to using unclean water. The nozzles are prone to clogging, so be gentle when cleaning to avoid damage; leaking from aged pipes is also common. If it's not these issues, it might be a faulty switch or poor circuit contact—using a multimeter to check voltage can help diagnose. For DIY checks, inspect the reservoir cap to ensure it seals properly; using dedicated washer fluid regularly can extend its lifespan.

It's really annoying when the windshield wipers don't spray water, especially when it's raining and the road is unclear. Check if the washer fluid is empty; the simplest solution is to refill it. The nozzle might be blocked by leaves, so try cleaning it. In winter, it often freezes; use the defroster or add antifreeze to prevent this. If none of these work, the pump or pipes may need replacement; it's safer to seek professional repair. Always test it once before driving to ensure safety.
