When you’re driving, visibility is crucial. Windshield wipers and washers play a significant role in keeping your view clear, especially during adverse weather conditions. However, what happens when your front windscreen washer doesn’t work, but the back one does? This can be a frustrating situation that many drivers encounter. In this article, we will dive deep into the reasons behind this issue and offer you practical solutions to troubleshoot and fix the problem.
Understanding the Windscreen Washer System
Before we jump into the troubleshooting part, let’s first understand how the windscreen washer system works. Your vehicle’s windscreen washer system consists of several components that work together to keep your front and rear windshields clean. The primary components include:
- Washer Fluid Reservoir: This is where the washer fluid is stored and usually located beneath the hood of your vehicle.
- Washer Pump: The pump draws fluid from the reservoir and sprays it onto the windscreen when activated.
- Washer Jets: These are the nozzles through which the washer fluid is sprayed onto the windscreen.
- Hoses: These connect the pump to the washer jets, allowing fluid to flow to where it’s needed.
The fact that your front windscreen washer isn’t functioning while the back one is can indicate issues within this complex system.
Possible Reasons for the Issue
There are several reasons why your front windscreen washer might not be working. Here are some common causes and complications to consider:

What could be causing my front windscreen washer to stop working while the rear one is operational?
The primary reasons for the malfunction of your front windscreen washer while the back one works can range from a clogged nozzle to a defective pump. Your vehicle’s windscreen washer system is designed to shoot fluid from the front and rear nozzles, but if there is a blockage in the line leading to the front nozzles, the fluid will not reach them. Debris, dirt, or even frozen fluid can accumulate in the nozzles, obstructing the spray.
Another common problem could be related to the pump that feeds fluid to the front washer. If the pump is malfunctioning or if there is a disconnection in the tubing specifically for the front washer, it could result in the front not functioning while the rear does. Checking these components can help isolate the issue and establish the next steps for repair or maintenance.
How can I check if the front windscreen washer nozzles are clogged?
To diagnose if the front windscreen washer nozzles are clogged, you can begin by visually inspecting them for any visible dirt or debris. Often, simply using a needle or pin to gently clear the nozzle openings can restore proper functionality. Ensure you do this carefully to avoid damaging the nozzle itself. After you’ve cleared the nozzles, try operating the washer system again to see if fluid sprays as expected.
Additionally, you can test if fluid is getting to the nozzles by disconnecting the tubing that leads from the pump to the front nozzles. If fluid is visible during activation of the washer pump, then the issue is indeed with the nozzles. If no fluid comes out, you may need to investigate further for a potential block or malfunction in the pump system.
What should I do if I suspect the washer pump is faulty?
If you suspect the washer pump to be faulty, the first step is to listen while you engage the front washer function. If you hear a humming sound from the pump but no fluid comes out, it suggests that the pump is operational but not delivering fluid.
