A functional windshield washer pump is essential for safe driving. The washer pump clears the windshield of any smears or smudges to ensure the driver’s view is undisrupted. A non-functional washer pump disrupts the driver’s view and can lead to potential accidents. If the washer pump is not working, there could be several reasons behind it. Let’s go through some common windshield washer pump problems and their fixes.
Windshield Washer Pump Problems
The windshield washer pump – one of the car pump types – allows drivers to clean dust, debris, smears, mud etc. from their car windshield with the touch of a button. However, this pump can develop problems over time such as clogged fluid lines and malfunctioning pumps among others. The diagnosis and repair of these problems are generally easy and cheap.

Washer Fluid Does not Spray Evenly
When you activate the windshield washer, the cleaning fluid should spray evenly across the windshield. However, if it concentrates at one spot or doesn’t spread evenly across the glass, there must be an issue with the washer pump. This can be caused by debris or dirt blocking the nozzle or fluid line. The dirt and debris lead to reduced pressure in the washer fluid pump. This results in an uneven spray across the windshield.
How to Fix
To fix this issue, you need to clear the clogged windshield washer nozzles. You must remove the nozzle from the spray wand. Use a pin or other tools to remove any debris blocking the nozzle. Force air through the fluid line to clear the line using an air compressor. If the air cannot pass through the line, you will need to replace the fluid line. However, if air does pass through it, the line is now clean and ready to be reinstalled.
Additionally, inspect the fluid reservoir if you see dirt or other contaminants in the fluid as they may cause the clogs. Flushing out the reservoir and replacing the fluid is your best course of action.
No Fluid Sprays Onto the Windshield
If no fluid squirts out when you activate the windshield washer, but the pump makes a humming or whirring sound, it is likely that the washer fluid reservoir is empty. It is recommended to check the windshield water fluid reservoir routinely to ensure this doesn’t happen.
How to Fix
You simply need to refill the fluid reservoir with a high-quality cleaner fluid. Activate the windshield washer once again and watch as it perfectly cleans the windshield. However, if the wiper fluid doesn’t spray after refill, you might want to take another look. It is possible that the fluid reservoir is cracked and leaking. In this case, you must replace the windshield water reservoir.
The Pump Doesn’t Engage When you Activate the Windshield Washer
If the windshield washer is still not functioning properly, open the hood of the car and listen for a humming sound coming from the pump. If there is no sound while the washer is activated, it is likely that the windshield wiper motor is malfunctioning or worn out. It can also be due to faulty wiring or other electrical issues within the pump.
How to fix
Head to the car fuse box and check if the fuse is blown. A blown fuse could indicate a dead pump. You can replace the fuse and get back to using the windshield washer without any issues. However, if the fuse blows again, you might need to change the pump.
On the other hand, if the fuse is intact but there is still no power in the pump, you might want to take a look at the electrical connection. Remove the pump wire connector and check for power with the help of a voltmeter. If the voltmeter shows no power even with an activated washer switch, the problem lies within the switch or the wiring. In this case, you must contact a professional and let the mechanic work out the electrical system.
In case the problem persists, it indicates a faulty or worn-out pump. Therefore, the old pump needs to be replaced. A mechanic will make the washer fluid pump replacement process easier for you.
