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.
