washer not squirting fluid on windshield on 1994 Chevrolet 2500 Pickup

My trucks windshield wipers work but nothing comes out when I try to use the washer fluid. There doesn't seem to be any leaking out of the hoses, the bottle is full of fluid. Is there something else somewhere to check or do I need to replace the pump?
Thank you
