Washer fluid idiot light when cold

[MBloch]

When it gets around 0 degrees and colder, my washer light and chime comes on when the tank has plently of juice (full).

Anyone else have this condition?

How do I make it go away?

Have you added water? use only mixed fluid. It might be freezing.

No, no water. Straight winter -20 washer fluid.

Is the washer still functional when the light and chimes come on? If not, it probably is freezing. I had to change to a -30 rated fluid.

I always use RainX washer fluid, and I too get the " washer fluid low" warning when it's very cold. It seems to happen at temps of -15 and lower, but goes away when the truck has warmed. Perhaps engine heat is warming the fluid. it always works fine, so I'm not going to worry about it. I'm guessing that it has something to do with the conductivity of the fluid . Any thoughts?
