Have you ever experienced a loss of wiper fluid? Running out of wiper fluid is not a good thing.
When you arrive at your destination after hours of driving, the last thing you want is to stop on the sidewalk with dirt on your windshield.
However, if you have just filled your windshield wiper fluid and it still isn’t flowing, read this article to find out why.
Why doesn’t the washer fluid flow?
There are many possible causes for washer fluid not draining. First, you need to make sure that the washer fluid reservoir is full and that the washer fluid is not frozen. If the fluid does not flow when filled, the nozzle may be clogged, the fuse may be blown, or the pump may be malfunctioning and needs to be replaced.
Reasons why wiper fluid is not spraying
- No washer fluid
- Clogged washer nozzle
- Blown fuse in washer pump
- Spray pump failure
- Diagnosing and repairing these problems is easy and inexpensive. Let’s take a closer look at each of them.
1. no washer fluid
First, check the amount of fluid remaining in the reservoir.
A typical windshield washer fluid reservoir contains approximately three-quarters to one gallon of washer fluid. This equates to 2.5 to 4 liters of fluid.
Washer fluid is one of the most important fluids in a car. It is important not only to keep the windows clean, but also to make the road easier to see when driving in the rain or snow.
As part of basic car maintenance, the amount of windshield washer fluid should be checked every time you refuel. Did you know that you can make your own windshield washer fluid?
If the fluid does not flow after filling, the washer nozzle may be blocked.
2. clogged washer nozzle or hose
If the washer fluid has just been added and the reservoir is full, the nozzle may be clogged. The pump is unable to push fluid out of the hose or nozzle and onto the windshield.
How do I unclog the windshield washer nozzle?
This is one of the most common causes of poor wiper fluid flow. The good news is that a clogged washer nozzle can be easily unclogged in a matter of minutes.
What you need
Sewing needle or nozzle needle
Blow out debris with compressed air.
Clogged nozzles in washing machines can be cleared by blowing debris out with air. Point the can of compressed air at the clog and blow on it until the clog is cleared.
This will remove any material that has become dislodged during use. Compressed air should also be used regularly to prevent clogged nozzles.
Use a sewing needle or nozzle needle
You can also use a sewing needle or nozzle needle to clean the nozzles of car wiper fluid. If you use a sewing needle, it should be small enough to be slightly larger than the nozzle hole.
A nozzle needle can also be used to unclog drains. It may be able to push or pull the debris that is causing the blockage.
Check the windshield washer hose
In addition to checking the wiper fluid lines and nozzles for clogs, you should also check the windshield washer system, including the wiper fluid hose under the hood.
Over time, the rubber material that connects the wiper fluid hose to the car can leak. This also causes the wiper fluid flow to slow down and the washer fluid to leak.
If the problem of no windshield fluid flow persists and washer fluid still does not flow, the fuse may have blown.
3. Blown washer pump fuse
A car’s electrical components are protected by fuses to prevent short circuits and electrical overloads.
If the wiper fuse blows, wiper fluid may not come out of the nozzle.
Replacing wiper fuses is easy and only takes a few minutes. To solve this problem, just follow these simple steps
What you’ll need
- A test light
- A replacement fuse of the same amperage as the original fuse.
- A fuse puller
Most cars have at least two fuse boxes. One is located under the hood and the other is located inside the car near the passenger side of the dashboard.
The location of the fuses can be found on the fuse box cover or in the owner’s manual.
Locate the blown fuse.
Test light or circuit tester. If your car has a test light, you can easily find a blown fuse by following these steps. If not, a circuit tester will suffice.
Remove the blown fuse and replace it with a new fuse of similar amperage.
For example, if a 15-amp fuse blows in the windshield wiper circuit, you will need to purchase another 15-amp fuse at an auto parts store.
If that fuse blows as well, you may need to replace the components in the circuit with one that matches the amperage of the fuse.
Reconnect the wiper fluid line and turn on the wipers. Spray a little fluid to make sure everything is working properly.
If nothing still comes out, take a closer look at the spray pump.
4. Faulty washer pump motor
The wiper fluid pump is connected to the fluid reservoir. If the electric motor for the washer pump is defective or stopped, it will not start even if activated by a switch.
