Windshield Wiper Fluid Not Coming Out? Davenport Auto Glass Expert Explains Why

Nothing is as frustrating as hitting the windshield washer button and seeing nothing happen. If your windshield wiper fluid is not coming out, it can compromise visibility and make driving hazardous, especially in bad weather. Understanding why this happens and how to fix it can save you time, money, and frustration. In this guide, Davenport’s auto glass experts break down the issue in this blog and provide practical solutions to get your washer system working again.

How Does a Windshield Washer System Work?

Before diagnosing the problem, we’ll help break down how your washer system operates!
When you activate the windshield washer switch, an electric pump draws the fluid from the reservoir and pushes it through small hoses to spray nozzles mounted on the hood or windshield cowl. The nozzles then distribute the fluid onto the glass, allowing the wipers to clear away dirt and debris. If any part of this system fails, the washer fluid will not spray properly.

Is It Safe to Drive Without Windshield Washer Fluid?

While it’s not illegal to drive without washer fluid, it’s highly unsafe and can result in accidents. Dirt, bugs, and road debris can quickly obscure your view, making it difficult to see and react to hazards. In winter, slush and salt buildup can make visibility even worse. Keeping your washer system in working order is essential for keeping you and your passengers safe!

Common Causes of Windshield Washer Fluid Not Coming Out

If your windshield wiper fluid isn’t spraying when you hit the switch, don’t panic. This is a super common issue—usually easy to fix. Here are some of the most common causes of windshield washer fluid not coming out:

• Empty or Frozen Reservoir: The most apparent reason? You’re out of fluid. Or, if you’re dealing with cold Davenport mornings, your fluid may be frozen if it’s not winter-grade.
• Clogged Spray Nozzles: Dust, dirt, wax, and even bugs can damage the nozzles and block the spray. If no fluid is coming out, this could be your culprit.
• Cracked or Disconnected Hoses: Your washer system uses tiny hoses to move fluid to the nozzles. If broken or knocked loose, it can leak before it sprays.
• Faulty Washer Pump: The washer pump pushes the fluid through the lines. If it’s worn out or failing, you won’t get any spray—even if the tank’s full.
• Blown Fuse or Electrical Issue: If the fuse connected to your windshield washer system blows, it cuts power to the pump. Without that power, the fluid won’t spray—no matter how full the reservoir is.

How Do I Fix a Windshield Washer Fluid System That Won’t Spray?

If your washer fluid isn’t spraying, don’t stress—here’s a simple step-by-step guide to help you troubleshoot the issue:

1. Check the Fluid Level

Pop the hood and check the washer fluid reservoir. If it’s empty, top it off with a fluid that matches the current weather conditions—especially during freezing temperatures.

2. Look for Leaks

Check under the car and along the hose lines for puddles or wet spots. You might have a cracked or disconnected hose if you spot fluid where it shouldn’t be.

3. Listen for the Pump

You should hear a faint humming sound. When you hit the washer switch, there is no noise. You could be dealing with a failed pump—or a blown fuse.

4. Clear the Nozzles

Grab a pin or fine wire and gently clean out the spray nozzles. You can also blast them with compressed air to remove gunk or debris.

5. Check the Fuses

Find your fuse box and locate the washer pump fuse. If it’s blown, swap it for a new one with the correct amperage.

6. Unfreeze the Fluid

If it’s cold out, your fluid might be frozen. Try parking in a heated garage or switch to a winter-grade washer fluid with a built-in deicer.

If you’re asking yourself, “Can I repair a broken windshield washer pump myself?”—the short answer is yes, but only if you’re comfortable doing minor car repairs. It’s considered a moderate DIY task, and if you’re up for it, here’s how to do it:

1. Locate the Washer Pump: It’s typically attached to the washer fluid reservoir.
2. Disconnect the Battery: Always disconnect power before working on electrical components.
3. Remove the Pump: Unclip or unscrew the pump from the reservoir and disconnect the wiring.
4. Install the New Pump: Attach the replacement pump, reconnect the wiring, and refill the reservoir.
5. Reconnect the Battery and Test: Power it back up and test the system to ensure the fluid sprays correctly.

Not all washer system issues indicate a failed pump. In many cases, simply refilling the reservoir or clearing blocked nozzles can restore proper function.

Regular maintenance—like checking fluid levels and cleaning spray nozzles—helps prevent future problems. If you’re unsure of the cause or the issue continues, professional windshield repair services like Kryger Glass can quickly diagnose the problem and provide a reliable fix.

What Kind of Windshield Washer Fluid Should I Use?

Not all washer fluids are created equal. Depending on your climate and driving conditions, you should choose a fluid that meets your needs:

• Standard washer fluid works well in mild climates and for general use.
• De-icing fluid is great for winter conditions. Its formula prevents freezing and helps melt ice on your windshield.
• Bug-removing fluid contains special additives to break down bugs, road grime, and tree sap.
• All-season fluid is highly versatile and works in various temperatures and conditions.

Using the correct fluid will prevent freezing, ensure clear visibility, and extend the life of your washer system!
