Rear window washer fluid - doesn't squirt

I can hear the rear washer pump running but get no fluid. Any common areas where the hose gets pinched? Also, is it possible that the hose will come loose in the roof at the squirter and show up as "wet seat belts"? Lsat time it rained they were both wet, but that is also when I tried to use the rear window washer....

How do I do the nozzel check? Do I have to drop the whole headliner? Is there a simple way to clean the nozzel?

I used a very fine wire and poked it in the squirter hole, tried it a few days in a row, tried the squirters for a number of days, then it started working. Inever disassembled anything.
