Thanks for this thread, mine washer pump would turn on but no fluid came out, sure enough the battery was on the hose

No one needs windshield washers, keep your G clean, you're good as long as the wipers are working correctly! And besides...I fu+king hate individuals that turn on their washers while driving ahead of me! (immediate road rage)

Just because you don't hear the washer fluid pump operating doesn't mean the pump itself is bad, unplug the connector, one side should have continuity to ground, the other side should have...?? 5v when the pump switch is operated from inside the car. If you don't have any voltage to the pump motor then troubleshoot the circuit back to the switch and it's fuse. If you have voltage then it's probably the washer pump motor, if you run the washer fluid reservoir dry you will burn that motor out in a heartbeat, never run it dry.
