They spray, but only when the headlights are on.

I lost two of my nozzles a couple years ago.

What happens, is that the water in the nozzles freezes, and cracks the plastic that holds them in place. Next time you use them, they eject!!!!

I ended up buying two new sets from sunset porsche in Oregon.

I never use the feature either, but hated having extra holes in the front of my car.
