My windshield wiper does move but the wiper fluid splashes very little like this is not enough force to cough out the wiper fluids.
( A little history, I changed my hood after an accident but the windershield was working very well together with the rate the fluid splashes till I changed the hood)
Checked for a kink in the washer fluid hose. Follow it from the pump all the way up to where it connects. You may also have a hole or tear in the hose. Then also check the nozzle - gently blow air threw it as it may be clogged. I would check the hose first. Then last the pump itself
