A Clearer View: What to Do If Your Windshield Washer Fluid Isn’t Working

If your windshield washer fluid is not coming out, there could be an easy fix. Learn why your windshield wiper fluid is not working and how to solve the issue at Ed Hicks Imports in Corpus Christi.

Your Mercedes-Benz is designed for smooth, effortless driving, but even the finest engineering needs maintenance. If you press the windshield washer button and nothing happens, it’s frustrating and, more importantly, a driving concern. A streak-free windshield is essential for visibility, whether you’re driving along Ocean Drive or heading out on the highway.

At Ed Hicks Imports, we know that small issues can affect your driving experience. If your windshield washer fluid isn’t coming out, the cause might be simple or require a professional fix. Here’s what might be happening and how you can get back to a clear view of the road.

My Windshield Wiper Fluid Isn’t Coming Out! What’s Wrong?

Your windshield washer system is a simple but crucial part of your car. When it stops working, one of these common issues could be the cause:

1. Clogged Washer Nozzles

If you hear the pump but no fluid sprays, the nozzles may be blocked. Dust, pollen, and wax buildup can clog the tiny openings.

Solution: Use a fine needle to clear out the debris or soak the nozzles in warm vinegar to dissolve buildup.

2. Low or Incorrect Washer Fluid

If your windshield washer fluid isn’t coming out, your reservoir may be empty, or the fluid may not be suited for your vehicle. Water-based solutions can also cause blockages. A washer fluid check is an essential part of your Service A scheduled maintenance, so check if your due to come in for service. 

Solution: Check the fluid level and refill it with Mercedes-Benz-approved washer fluid to maintain smooth performance.

3. Blown Fuse

If you press the button and hear nothing, the fuse controlling the washer pump may be blown.

Solution: Check your vehicle’s fuse box and replace the washer system fuse if needed. If the new fuse blows quickly, there may be an electrical issue.

4. Faulty Washer Pump

The washer pump moves the fluid from the reservoir to the nozzles. If it fails, no fluid will reach the windshield.

Solution: If the fuse is fine but you don’t hear the pump running, it may need to be replaced. Our Mercedes-Benz service specialists can help diagnose the issue.

5. Leaking Washer Fluid System

If your fluid runs out unusually fast or you see a puddle under your car, a leak could be the issue.

Solution: Inspect for cracked hoses, a loose reservoir cap, or damaged connections. A professional inspection can pinpoint the leak.

6. Frozen or Thickened Washer Fluid

Cold weather can thicken certain washer fluids, blocking the system.

Solution: Use all-season washer fluid to prevent clogging. If the fluid has already thickened, warming up the vehicle may help.

7. Electrical Problems or a Faulty Switch

If your windshield washer fluid isn’t working and the fuse is fine, the issue may be in the wiring or control switch.

Solution: A technician can check the wiring, relays, and control module to ensure proper function.

How to Fix a Windshield Washer That’s Not Working

Some issues are easy to troubleshoot at home, while others require expert service. Here’s what you can do:

  • Check the fluid level and refill it if needed. 
  • Unclog nozzles using a pin or compressed air.
  • Inspect for leaks in the hoses or reservoir.
  • Replace a blown fuse if the pump isn’t running.
  • Listen for the pump. If it’s silent, it may need replacing.

If the problem persists, let our Mercedes-Benz technicians handle it.
