low windshield washer fluid level warning

I have a 97 that the "low washer fluid" light comes on in the display every time the car is started. The washer tank is full to the brim. I thought is was probably a stuck float or something, but because of the filter screen in the neck of the tank, I can't get anything past there to try to free up the float, if there is a float setting off the warning.

Anyone with the same problem?

I've heard of this, no direct experience though...
Yes the float is stuck. Maybe lightly rapping the assembly on something would free it up ?

I had the same problem and it just went away. I let the fluid inside the tank get low, and the problem fixed itself.
