You can tell if your windshield sprayer is clogged if the spray pattern is weak or nonexistent when activated. Additionally, if you hear the pump running but no fluid is coming out, this is a strong indicator of a blockage. You might also notice that the fluid is dripping from the nozzles rather than spraying. Inspecting the nozzles for visible debris and checking the fluid lines for kinks can help confirm a clog.

To get soap to flow from the sprayer nozzle, ensure the nozzle is turned to the "on" position. Check that the soap container is properly filled and securely attached to the sprayer. If the soap is still not coming out, try gently squeezing the trigger or pumping the sprayer a few times to build pressure. If it remains clogged, inspect the nozzle for debris and clean it if necessary.

Normally you can stick a safety (or other stout) pin that fits in the nozzle and move it that way. Most all nozzles are adjusted this way. Trial and error.
