You probably have a broken vaccum line going to that washer or plugged nozzle. Raise the hood and follow rubber lines from the washer nozzles to the fluid tank looking for leak in hose or broken. Repair as needed with plastic splicer, or new piece of hose, both available at any local parts store. If nothing is found wrong with hoses stick a sraight pin or needle in the holes of the nozzle to clean plug.
