The nozzles that spray my windshield washer fluid really suck one sprays a jet past my windshield and another sprays maybe 4 inches i feel like something is clogging them but they've been this way since i can remember. Any advice on what i can do to fix this?

Edit: Also does anyone know the part number for a new key fob either the Chrysler or Mercedes one. the top of mine broke so i can't have it on a key chain or lanyard.
