Knowing how it works and how critical it is for safe driving can help you appreciate why, when it stops working, it’s not just a minor annoyance but a safety issue.
Common Reasons Your Windscreen Wiper Fluid Isn’t Working
If you find your windscreen wiper fluid isn’t working, it could stem from several factors. Here are the most common reasons why:
1. Empty Reservoir
The first and most obvious reason is that the reservoir is empty. If your windscreen wiper fluid hasn’t been replenished in a while, it could simply be that you’ve run out.
2. Clogged Nozzle
Over time, dirt and debris can build up in the nozzles where the fluid exits. This can significantly hinder the amount of fluid being sprayed onto your windshield.
3. Broken Pump
The pump is responsible for pushing the windshield washer fluid from the reservoir to the nozzles. If the pump has malfunctioned or is broken, the fluid won’t reach the windshield.
4. Leaking Reservoir
If there’s a leak in the reservoir, the fluid may escape before it can be used. This often results in a puddle of fluid under your vehicle when parked.
5. Frozen Fluid
In cold weather, the windshield washer fluid can freeze inside the reservoir or the lines, rendering it ineffective until temperatures rise.
6. Faulty Electrical Connection
If there’s an electrical issue causing the pump to not receive power, the fluid will not be dispensed. This could be due to a blown fuse or a disrupted connection.
Diagnosing the Problem
Once you’ve identified potential reasons why your windscreen wiper fluid isn’t working, it’s time to diagnose the problem systematically.
Step 1: Check the Fluid Level
The easiest step is to pop the hood and check the windscreen wiper fluid reservoir. Make sure that it is filled up to the required level. If it’s empty, refill it with the appropriate fluid.
Step 2: Inspect for Leaks
If you find that the level is low despite recent refilling, inspect the reservoir for signs of leaks or cracks. Look for wet spots or puddles beneath the car.
Step 3: Examine the Nozzles
Using a small pin or needle, clear any debris that might be clogging the nozzles. Spray a small amount of fluid to check if it comes out.
Step 4: Test the Pump
You can test if the pump is working by having a friend press the wiper fluid button while you listen near the reservoir. If you hear the motor running but the fluid doesn’t spray, the problem likely lies within the hose or nozzles.
Step 5: Check the Electrical Connections
Consult the vehicle’s manual to locate the fuse for the wiper fluid pump. Inspect it to see if it is blown. If necessary, replace it and test the system again.

What causes windscreen wiper fluid to stop working?
The primary reason your windscreen wiper fluid might stop functioning is a clogged nozzle or hose. Over time, debris, dirt, or even hardened fluid can build up, blocking the pathway that fluid travels through. This blockage can prevent the wiper fluid from reaching the windscreen, leaving your view impaired.
Another common cause could be a faulty pump. The pump is responsible for pushing the fluid from the reservoir to the wiper nozzles. If the pump fails due to electrical issues or physical damage, the fluid won’t be dispersed, which can be frustrating, especially during adverse weather conditions.
How can I tell if the wiper fluid reservoir is empty?
You can typically identify an empty wiper fluid reservoir by checking the fluid level indicator, if your vehicle has one. This indicator is usually marked on the reservoir itself, showing “FULL” and “LOW” levels. If you don’t see any fluid at the visible level, it’s a good chance that the reservoir is empty.
In addition, you might notice that when you activate the wiper fluid, nothing sprays onto the windscreen. If you hear the sound of the pump running but no fluid comes out, that can also indicate an empty reservoir or a blocked line preventing the fluid from flowing.
What should I do if the wiper fluid is clogged?
To clear a clogged wiper fluid system, start by inspecting the nozzles for any visible blockages. You can use a pin or needle to gently clear any dirt or debris obstructing the nozzle openings. Make sure to do this carefully to avoid damaging the nozzle.
If the blockage persists, you may need to check the hoses connected to the nozzles. Detach the hose and gently blow through it to see if air flows freely. If there is still a blockage, you might need to replace the hose or use a cleaning solution to flush out any stubborn debris.
Is it safe to use water instead of windshield washer fluid?
Using water may seem like a simple solution, but it’s not recommended as a long-term substitute for windshield washer fluid. Water can freeze in colder temperatures, which can lead to cracking of the windshield if you spray it during frosty conditions. It also lacks the cleaning agents found in proper washer fluid, which can result in streaks and ineffective cleaning.
Moreover, water alone does not prevent the buildup of grime and can leave behind mineral deposits that cloud your windscreen over time. Investing in a quality windshield washer fluid is advisable for optimal performance and protection against weather elements.
How can I fix a faulty washer fluid pump?
If you suspect your washer fluid pump is faulty, start by checking the electrical connections. Ensure that all wiring is intact and that there are no disconnections. If the connections are sound, you may want to test the pump by applying direct power to it. If the pump does not operate, it will likely need to be replaced.
Replacement is typically straightforward, as you can purchase a compatible pump from an auto parts store. Follow your vehicle’s manual instructions for removing the old pump and installing the new one. It’s also a good idea to check the fluid reservoir during this process to ensure it’s free from obstructions.
What type of washer fluid should I use?
When selecting washer fluid, it’s best to choose one that is specifically formulated for automobile use. Many products are available, with options for seasonal usage, such as summer formulations that clean better and winter blends that resist freezing. You should select the type that suits your local climate conditions.
Additionally, consider looking for washer fluids that are marked as safe for use on tinted windows or that contain anti-foam and anti-smear additives. These features improve visibility and performance, ensuring your windscreen remains clean and clear while driving.
Can low temperatures affect the wiper fluid’s performance?
Yes, low temperatures can significantly affect the performance of wiper fluid. If the fluid is not designed for colder climates, it can freeze in the reservoir or the nozzles, obstructing flow. Many standard windshield washer fluids are not formulated to withstand sub-zero temperatures, leading to inadequate performance during winter months.
To counter this issue, it’s essential to use a washer fluid rated for cold weather. These formulas include antifreeze agents designed to remain liquid even in freezing conditions, ensuring that you have clear visibility whenever you need it.
What are the signs that I need to replace the wiper fluid reservoir?
Signs that you may need to replace your wiper fluid reservoir include visible leaks beneath your vehicle and a significant drop in fluid levels despite regular refills. If you find puddles beneath your car or notice fluid pooling near the reservoir, it’s a clear indication that there’s a crack or rupture in the reservoir.
Another symptom is the presence of moisture or fluid in areas around the reservoir that should remain dry. If you consistently lose fluid even when the system is functioning correctly, it might be time to have the reservoir inspected and potentially replaced to prevent further inconvenience.
