Mine stopped working this winter because the cheap blue water Valvoline put in at one of my oil changes froze in the line. Once I got it flowing again, I found washer fluid leaking out of the rear lift gate. I pulled the inside panel off and found there is a pressure relief valve that had popped open and that is what was leaking. I snapped in closed and everything works great now. It is right by the wiper motor in the lift gate.

So if your pump is working, check in the back for leaking fluid. It could be that valve.

OP, If you haven't already, just check to make sure the hose isn't crimped at the wiper arm... It's happened to me once or twice, the nozzle just slides down a bit and crimps the hose.

The rear panel just prys up... There's an article on installing a rear-view camera that shows how to do it...
