My low wash light is on for some reason.
The washer fluid tank has a level sensor. The sensor floats in the tank. When the fluid gets low, the sensor makes contact with the metal ring around the float and the light comes on. Sometimes the float stays stuck even after you add liquid. A simple bump with your hand might dislodge it and get it back to floating. If that doesn’t work, I would recommend having a certified mechanic check your washer fluid system and have the appropriate fixes made on your car.
