Washer wiper not working, possibly used when

The fuse is the same as for the wipers and push on washer switch and see if you can hear washer pump run,otherwise try this (unless the motor pump has been dry run too long and ruined pump assy) and can't pump any longer go to a garage that has compressed air and at the wiper nozzles first gently blow air into each nozzle, then go to reservoir and remove supply hose to wiper nozzles and blow air gently and see if there's an obstruction in the line, you can use say 30 lbs max,reason being if any hoses where you cant get to them they can blow off fittings, also take air hose and on top of reservoir blow into hole on top of reservoir to push product thru lines and help pump (same as removing hose) on reservoir, I bet its unprimed itself or blocked with dirt,try this first
