Windshield washer pump-Pumping but no fluid

Washer pump is working but nothing is coming out. Tank is full. Is there a certain part of the system that can get plugged? It's not coming out of either wiper so it sounds like something is plugged somewhere. My Cav is a 2004. Many thanks!

they do and can freeze.

the sprayers can get clogged. Get a needle and wiggle around the sprayers.
