Dealing with windshield wiper fluid that does not spray can be frustrating, especially when you need it most. This comprehensive guide will help you diagnose and fix the issue, ensuring your vehicle's wipers function as they should. Whether you're a do-it-yourself enthusiast or a seasoned mechanic, this article will provide valuable insights and practical steps to resolve the problem.

Understanding the Problem

The issue of windshield wiper fluid not spraying can arise from various reasons. The simplest and most common problem is blocked nozzles. However, it could also be due to damage or misalignment of the nozzles, failure of the washer pump, or even a blown fuse. It's crucial to identify the exact cause before proceeding with any repairs or maintenance.

Potential Causes and Solutions

Nozzles Blockage

The first step in diagnosing the problem is to check for nozzles blockage. The simplest solution is to clear the nozzles using a pin. This is often sufficient for cases where blockages are minor. Clearing the nozzles ensures that the water spray is directed correctly and the wipers function as intended.

Washer Pump Failure

If clearing the nozzles does not resolve the issue, the problem might lie with the washer pump. A faulty or failing washer pump will not produce the whirring sound that accompanies the activation of the spray function. To check the washer pump, inspect the reservoir and listen for the motor's whirring. If the sound is absent, you might need to check the supply lines and components for damage or connection issues.

Supply Line and Connection Issues

Another potential issue is the thin plastic tube from the pump to the nozzle. This tube can become twisted, compressed, or damaged, preventing the fluid from reaching the nozzles. Inspect the tube for any signs of damage or misalignment and correct any issues you find. This includes ensuring that the tube is not kinked or damaged and that it's properly connected to both the pump and the nozzles.

Common Symptoms and Diagnostic Checks

When windshield wiper fluid does not spray, you might notice several symptoms. These could include:
