On my trip to Philadelphia this past weekend, the temperature was between 28 and 32 degrees. Fairly clear roads on the way there, and my windshield washer fluid refused to spray. It worked in the garage, and a few times at the beginning of my trip. When I most needed it on the Turnpike, it stopped spraying, though I could hear the pump. I stopped at a service plaza and filled the tank with fluid, thinking it had emptied, but still nothing. Sound of pump, no spray.

I parked it in the garage at the Philly Sheraton, and the next day it worked just fine. Came out with pressure washer force.

On the way home, while the roads were not so clear (see photos), the sprayer stopped working again. Nothing to do with the nozzle at the windshield, as it is clear. I've never put plain water in the bottle.
