Windshield Fluid not spraying anymore

They used to spray and now and dribbles a 6" stream on both sprayers.
Its 10 degress F here and I have winter fluid for these freezing temperatures, so I don't know what it could be ? Clogged lines with dirt I imaigine but dont know how where to find the lines running to the sprayers. I unscrewed a sprayer and didnt know how to take it apart ?
I dont have a manual so i cant look at the whole Windshields washer fluid system.
