Windshield Wiper System Not Working: Causes and Solutions

There are few things more frustrating than a windshield wiper system that fails to work, especially in bad weather. But don't worry – many problems with the windscreen wiper system are relatively easy to diagnose and fix. In this blog post, we'll look at the most common causes and show you how to solve them.

1. Check the Wiper Fluid

Start with the obvious: make sure there is enough wiper fluid in the reservoir. If the reservoir is empty, fill it up with a suitable wiper fluid. Make sure to use a solution containing antifreeze in winter to prevent freezing.

2. Clogged Nozzles

Blocked spray nozzles are a common cause of problems. Check whether the nozzles are blocked by dirt or deposits. These can often be cleaned with a fine needle or a thin wire. Be careful not to damage the nozzles in the process.

3. Check the Pump

If the wiper water does not spray, the windshield wiper system pump may be defective. Listen to the sound of the pump when operating the system. If you do not hear any noise, check the fuses and connections to the pump. It may be necessary to replace the pump if it is defective.

4. Check Lines and Hoses

Occasionally, lines or hoses that carry the mop water to the nozzles may be kinked, clogged or leaking. Check them for obvious damage and make sure they are properly connected. Damaged lines should be replaced.

5. Electrical Problems

If the wipers themselves are not working, the problem could be electrical. Check the fuses and relays connected to the wiper system. A faulty relay or blown fuse may be the cause and can be easily replaced.

6. Replace Wiper Blades

Even if the wiper blades have nothing directly to do with the function of the wiper system, they do influence the cleaning performance. Make sure that the wiper blades are in good condition and replace them when worn to ensure optimum visibility.

Conclusion

Most problems with the windshield wiper system can be fixed by yourself with a little patience and basic technical knowledge. However, if you feel unsure or are unable to solve the problem, do not hesitate to visit a specialist garage. Your safety and that of your passengers should always come first.
