Have you experienced a windshield wiper fluid not coming out scenario? It’s never a good time to run out of wiper fluid.
If you’ve been driving for hours and are coming to your destination, the last thing you want to do is pull up to the curb with streaks of dirt running down your windshield.
But if you’ve just refilled the wiper fluid and it’s still not coming out, you might need to read this article to find out why.
Why your windshield washer fluid won’t come out
There are many potential reasons why your windshield washer fluid won’t come out. First, you have to make sure that the washer fluid reservoir is full and the washer fluid is not frozen. If there is no fluid coming out after refilling, you may have a clogged nozzle, blown fuse, or the pump is broken and needs to be replaced.
Reasons Windshield Wiper Fluid Doesn’t Spray
- No Washer fluid
- Clogged washer fluid nozzles
- Blown washer pump fuse
- Faulty spray pump
Diagnosing and fixing these problems is easy and cheap. Let’s discuss each one in detail.
1. No washer fluid
The first step is to check the amount of fluid left in the reservoir.
A typical windshield washer reservoir can hold around three-quarters to a gallon of windshield washer fluid. This is equivalent to 2.5 and 4 liters of fluid.
Washer fluid is one of the important fluids of a car. It’s not only important for keeping your glass clean, but it also helps you to see the road while driving in rain or snow.
As part of basic car maintenance, you have to check your washer fluid every time you fill the gas tank. Did you know that you can make your own wiper fluid?
If there is still no fluid coming out after adding more, you may have a clogged windshield washer nozzles.
2. Clogged windshield washer nozzles or hose
If you just refilled your windshield washer fluid and the reservoir is full, you may have a clogged nozzle. The pump cannot push the fluid through the hose or nozzles and onto your windshield.
How to unclog windshield washer nozzle
This is one of the most common reasons why windshield wiper fluid won’t spray. The good news is that you can easily unclog the windshield washer nozzle in a few minutes.
What you’ll need:
Step 1: Use compressed air to blow away debris.
You can clear a clogged washer nozzle by using air to blow debris out of the way. Hold a can of compressed air pointed at the clog and spray it until the clog comes loose.
This will clear out any material that might have come loose during use. If used regularly, compressed air will also help keep the nozzles from clogging up regularly.
Step 2: Use a sewing needle or a nozzle needle
You can also use a sewing or nozzle needle to clean your car’s wiper fluid nozzles. If you choose to use a sewing needle, make sure it’s very small – preferably one that’s only slightly larger than the nozzle hole.
You can also use a nozzle needle to clear the clog. You may be able to push through or pull out whatever debris is causing the clog.
Step 3: Check windshield washer hose
While it is a good idea to check for clogs in your wiper fluid lines and nozzles, you should also check the washer system including the wiper fluid hose under the hood.
Over time, the rubber material that connects the wiper fluid hose to the car may leak. This may also explain why your wiper fluid is not spraying freely or why windshield washer fluid is leaking.
If the windshield fluid not coming out issue persists, your windshield washer fluid still won’t come out, you may have a blown fuse.
3. Blown washer pump fuse
Your car electrical car accessories are protected by a fuse to prevent shorts and overloading of electricity.
If the fuse of your wiper blows, then you would experience the windshield wiper fluid not coming out of the nozzles.
A blown wiper fuse is easy to replace and only requires a few minutes. To fix the problem, just follow these simple steps:
What you’ll need:
- Test light
- Replacement fuse of the same amperage as your original one.
- Fuse Puller
Most cars have at least two fuse boxes. One is located under the hood, the other one inside the car near the passenger side of the dashboard.
You can find the location of the fuse on the fuse box cover or in the owner’s manual.
Step 1: Find the blown fuse.
Step 2: Remove the blown fuse and replace it with the new one of a similar amp rating.
For example, if you have a 15 amp fuse that blew in your wiper circuit, you need to get another 15 amp fuse from the auto parts store.
If this fuse also blows, you may need to replace a component in the circuit with one compatible with your fuse rating.
Step 3: Test it again.
Reattach the wiper fluid line and turn on the wipers. Spray some fluid to make sure everything works fine.
If there is still nothing coming out, it is time to take a closer look at the spray pump.
4. Faulty washer pump motor
The wiper fluid pump is connected to the fluid reservoir. When the windshield washer pump electric motor fails or ceases to work, it won’t turn on when activated by the switch.
It is possible for the pump to fail, which means that you can hear the motor running but windshield fluid is not coming out.
What you’ll need:
- Test light
- Washer pump motor
Step 1: Locate the washer pump at the bottom of the reservoir.
Step 2: Attach the test light clip again
Have someone turn on the washer nozzles and probe the back of the connector on the pump. When a power supply is verified, it confirms that the washer pump motor may need to be replaced.
You can either do this repair on your own, or you can have a qualified professional perform the work for you. A warranty is included with most repairs undertaken by pros.

I hope all of these steps help you fix the windshield wiper fluid not coming out issue as easily as possible. If after all of this your wiper fluid still hasn’t returned, it may be time to replace the whole assembly.
