Keeping your windshield clean is essential for safe driving, which is why a functioning washer fluid pump is critical for your vehicle. If you’ve noticed that your washer fluid isn’t spraying when you need it, it can be both frustrating and unsafe. In this comprehensive article, we will explore the common reasons why your washer fluid pump might not be working, the potential solutions, and how to keep this vital component in working order.
Understanding the Washer Fluid Pump System
The washer fluid pump is a small but crucial component of your vehicle’s windshield wiper system. It is responsible for delivering washer fluid from the reservoir to the wiper blades to clean your windshield. When you pull the lever to activate the wipers, the pump should engage and spray washer fluid onto the glass.
Components of the Washer System:
1. Washer Fluid Reservoir: The container that holds the washer fluid.
2. Washer Fluid Pump: Draws the fluid from the reservoir and pumps it through the hoses to the nozzles.
3. Hoses: Transport the fluid from the pump to the windshield.
4. Nozzles: Spray the fluid onto the windshield to aid in cleaning.
Common Reasons Why the Washer Fluid Pump Isn’t Working
Before you can fix the issue, it’s important to understand what might be causing the problem. Here are the most common reasons why a washer fluid pump may not be working:
1. Low Washer Fluid Level
One of the simplest reasons for a malfunctioning washer fluid pump is a low washer fluid level. If the reservoir is empty, the pump will have nothing to draw from, and you won’t get any fluid sprayed on your windshield.
2. Electrical Issues
The washer fluid pump relies on electrical power to operate. Issues such as blown fuses, corroded connectors, or damaged wiring can affect its performance. If the pump motor isn’t receiving power, it will not engage.
3. Clogged Nozzles
Over time, the nozzles can become clogged with dirt, grime, or hardened washer fluid. A clogged nozzle can prevent fluid from being sprayed onto the windshield, making it seem like the pump isn’t working.
4. Faulty Pump
Like any mechanical component, the washer fluid pump can wear out or fail. A defective pump will not be able to perform its job, necessitating a replacement.
5. Frozen Fluid
In cold weather, washer fluid can freeze, particularly in the reservoir or the hoses. If the fluid is frozen, the pump may not be able to push it through the system.
Troubleshooting Your Washer Fluid Pump
If you’re experiencing issues with your washer fluid pump, follow these troubleshooting steps to identify and address the problem.
Step 1: Check Washer Fluid Level
The first step is to make sure there is enough washer fluid in the reservoir.
- Open the hood: Locate the washer fluid reservoir, which usually has a symbol of a windshield and wipers on the cap.
- Check the fluid level: If the level is low, refill it with an appropriate washer fluid. Make sure not to use plain water, as it can freeze or evaporate quickly and doesn’t clean effectively.
Step 2: Inspect Fuses and Wiring
If the fluid level is adequate, the next step is to check the electrical components.
- Locate the fuse box: This is usually under the dashboard or in the engine compartment. Consult your owner’s manual for the specific location.

What are the common symptoms of a faulty washer fluid pump?
The common symptoms of a faulty washer fluid pump include a lack of spray from the windshield washer nozzles, unusual noises when attempting to activate the washer fluid system, or inconsistent fluid delivery. If you notice that the windshield cleaner doesn’t spray when you engage the wiper control, it could indicate a problem with the pump, electrical connection, or fluid supply.
Another sign may be that the fluid reservoir is full, but you still don’t see any output when the pump is activated. This could mean there is a blockage in the tubing leading to the nozzles, or that the pump itself is damaged or burnt out. Conducting a visual inspection can often help you identify these issues quickly.
How can I check if my washer fluid pump is functioning?
To check if your washer fluid pump is functioning, start by listening for any sound when you activate the windshield washer. If you don’t hear a humming or buzzing sound, this may indicate that the pump is not receiving power or is damaged. You can test the power supply with a multimeter to ensure that it is getting the required voltage.
If the pump is receiving power but still not operating, you should remove it from the washer fluid reservoir and test it directly. This can usually be done by applying power directly to the pump’s terminals. If it runs outside of the reservoir, you may need to look for blockages in the hose or faulty nozzles.
What should I do if my washer fluid pump is not receiving power?
If your washer fluid pump is not receiving power, the first step is to check the fuse associated with the washer fluid system. A blown fuse can prevent the pump from functioning. Consult your vehicle’s manual to locate the correct fuse and replace it if necessary. Make sure to use a fuse with the correct amperage to avoid future electrical issues.
If the fuse is intact, you should inspect the wiring and connections leading to the pump. Look for any signs of wear, corrosion, or loose connections. Repair any damaged wires, clean corroded connectors, and ensure everything is securely connected to restore power to the pump.
Can a clogged washer fluid hose cause the pump to malfunction?
Yes, a clogged washer fluid hose can definitely cause the pump to malfunction. When the hoses that transport the washer fluid become blocked with debris, dirt, or even old fluid residue, it prevents the fluid from reaching the nozzles, leading to a poor or nonexistent spray. A pump that’s running without any outlet due to a blockage can also potentially overheat and become damaged.
To address this, inspect the hoses for any visible clogs. You can flush the hoses with water or use a compressed air tool to clear out any blockages. In severe cases where the hose is damaged or heavily corroded, replacement may be necessary to restore proper function.
