Understanding Your Vehicle’s Washer Fluid System
Knowing how your car’s washer fluid system works is key. It keeps your windshield clean and clear, even when it’s bad outside.
How the Washer Fluid System Works
The system uses a pump to pull fluid from a tank. It sprays the fluid on your windshield through nozzles. You turn it on with a switch on your dashboard or steering wheel.
The system has a sensor to check the fluid level. If the level gets too low, the sensor lights up a warning on your dashboard.
Components of the Washer Fluid System
The system has a few important parts. The reservoir holds the fluid, and its size depends on your car. The pump pulls the fluid out and sprays it on your windshield.
The nozzles spread the fluid all over your windshield. This makes sure it gets clean. The sensor checks the fluid level and tells you when it’s time to refill.
Why Your Washer Fluid Low Light Won’t Turn Off

Knowing the difference helps you fix the problem. You might need to refill the washer fluid or check the sensor.
