Apparent clog in wiper fluid system

This problem just started this morning. When I tried to run my wipers with the washer fluid, the wipers started with no problem. Only a tiny bit of fluid came out and stopped. I thought it might be empty, so I got some more and filled it up. Nothing has changed. When I press the end of the turn signal in, I get a very quick squirt of fluid, I hear the pump whirring, but nothing after that. I think it's got something blocking the flow.

How do I remove the reservoir so I can look for junk inside it? Is there a screen at the bottom to catch large pieces of stuff? Should I just stick something in and see if I can move anything? Any other advice?

Normally aftermarket fluid causes problem i.e.: Rainex, etc. check for nozzle blockage first. Attached reservoir instructions & parts info.
