The importance of windshields in cars cannot be ignored, as they protect the driver and passengers. Moreover, especially in the case of severe car accidents, it prevents the passengers from ejecting from the vehicle avoiding severe injuries (2).
The drivers can clean their windscreens using washer fluid and wipers to get a clear viewpoint (3). However, if your car is flashing the washer fluid warning sign, it can indicate that the washer fluid in the vehicle has finished and that you need to refill the reservoir. Similarly, there can be other reasons to display this sign on the car’s dashboard.
Importance of Car’s Washer Fluid
You might have experienced driving through mud or pollen that makes the windscreen dirty, blocking your road view.
Without this fluid, a driver would have a dirty windshield, ultimately compromising road safety (3). Another important function of washer fluid is keeping the washer pump lubricated. Unfortunately, there are many car models where the washer pump gets rusted, corroded, or leaked when there is no liquid in the washer fluid reservoir. Similarly, there is a chance that the car’s washer pump will get destroyed if insufficient liquid is in the reservoir (2).
There is a chance of developing frost on the windscreen during winter and bacteria during the summer season. In this case, filling the washer fluid reservoir with appropriate liquid can help eliminate the ice and bacteria on the windscreen. You should also check the washer fluid nozzle, wiper blades, and the washer fluid reservoir (1). A perfectly intact rubber blade will provide the best cleaning experience, but if the wiper rubber blades are peeling off, then there is a chance that the windscreen will get scratched. Thus, you should check the wiper blades and nozzle for adequate windshield cleaning.
What is the Best Washer Fluid?
Although many washer fluid brands are available in the market, you can easily make the washer fluid at home (1). Drivers use different methods to make their washing fluid. The best and most effective washer fluid can be a good window cleaner. So, you can dilute the window cleaner by mixing one part of the window cleaner with three parts of distilled water. This will make you a perfect windscreen washer fluid (2).
In this case, mix one part of white vinegar with three parts of water to form a diluted vinegar solution. You can also add a few drops of dishwasher liquid for added cleaning properties. Ammonia and water solution are the best washer fluid to get rid of heavy mud and dust. Ammonia is present in the dishwasher liquid, so you can mix the dishwasher liquid with water to form an ammonia solution. However, ensure that the dishwasher liquid is manageable and manageable to make an optimum solution. Finally, alcohol, castile soap, and water can make the washer fluid. In this case, take one part of alcohol and castile soap to be mixed in one gallon of water. This will also make you a perfect windscreen washer fluid.
Reasons that the Washer Fluid Warning Light is displaying on the dashboard
Following are a few reasons that can display the washer fluid warning light on the dashboard:
Low Washer Fluid in the Reservoir
The most obvious reason for displaying the washer fluid warning light is that the washer fluid level is low in the reservoir. A reservoir sensor detects the level of liquid in the reservoir fluid (3). If the reservoir fluid is low, the sensor sends a signal to the car’s ECU that illuminates the washer fluid warning light.
In this case, you are recommended to find the washer fluid reservoir of your car. Most vehicles have their washer fluid reservoir located inside the bonnet that can be easily located. The reservoir is a white plastic container containing a lid with the windscreen washer sign. You can lift the lid and fill the reservoir with the desired fluid. If you find it challenging to locate the washer fluid, you can take the car to a service center to get the washer fluid refilled in the car’s reservoir.
The faulty washer fluid reservoir lid can also flash the washer fluid warning sign on the vehicle. A faulty lid will not save the washer fluid inside the reservoir.
So, a faulty lid can flash a washer fluid warning sign on the vehicle’s dashboard. Similarly, any leakage in the reservoir can also flash a warning sign. In any case, the reservoir needs a replacement (3).
In case your washer fluid reservoir lid is faulty, try getting the reservoir replaced. You can order the reservoir through online stores or take your car to a professional service center to get the reservoir replaced.
Faulty Reservoir Sensor
As discussed above, the reservoir sensor detects the liquid level inside the reservoir and indicates low-level fluid to the car’s ECU (2).
In this case, try cleaning the reservoir sensor with soapy water. If the problem pertains, try getting the sensor replaced by consulting a professional mechanic.
I used to have a Ford Focus 2015 that displayed a washer fluid warning sign. I considered this sign to indicate a low fluid level, so I filled in the washer fluid, and the sign disappeared momentarily. After driving a few kilometers, the washer fluid warning sign again started displaying on the dashboard. This time I thought there was an issue with the sensor, and my car showed a false warning sign. Unfortunately, there was a dust storm later that day, and when I pressed the knob to rinse off my windscreen, there was no washer fluid in the reservoir. So, I had to drive with a considerably blocked view of the road. When I got home, I discovered the washer liquid reservoir was leaked. So, give a few minutes after filling in the reservoir and check the reservoir liquid level before driving. If there is a leak in the reservoir, the fluid level will decrease, and you can take timely steps before driving.
