Hi
I'm not sure what it is but my washer bottle has a float with what appears to be
a fiber optic cord attached, the cord attaches to an indicator on the dash.
The float has disintegrated so if anyone has a bottle with a float in it I would like to buy it.
Thanks
Bill

 

I believe that device is the low washer fluid level indicator system. There's a little light under the wiper switch on your dash?

 

Yes that's the one.
Thanks
Bill
