1. the washer fluid jets are plugged possibly and will not allow fluid to discharge. Take a small wire or needle and stick into the jet end where the fluid comes out and it should spray after that if that is the issue.2. the lines coming from the washer pump could be broken or cut open. Remove the line at the back of the spray jet either at the hood or at the wiper arm, then attempt to spray the wiper fluid. If it does not spray then there is an open/broken line coming from the washer pump or the pump may have a problem. If fluid is coming out of the line, the jet again is plugged up. Also check to see that fluid is going into the washer pump (locating the pump and getting to it is sometimes not so easy depending on where the mfg put the pump).
