windshield washer on 2001 Pontiac Grand Prix

When I try to wash my windshield no wash fluid comes out. Is there some kind of a pump on it that could be shot? We blew the lines out and that wasn't it.

Look at #18 washer pump http://www.parts.com/schematics/F/FD97510.gif located at the bottom of #14 washer fluid reservoir about $35 at www.napaonline.com
