I'm having similar issues with my washer fluid system. I checked the fuse in the set under the steering wheel - it's one fuse for the wiper blade motor and the fluid motor, and the blades work.

I used a 12v battery to power the washer fluid motor and it squirted the blue stuff with no problems.

Multimeter shows no voltage and resistance of 1 at the wiring harness that connects to motor when the system is activated. Are there any other fuses / relays i'm not aware of. Could this be the switch in the steering column, or does the wiper blade control module have anything to do with the fluid motor?

I'm not looking forward to jacking around with all the wiring and a multimeter if it comes to that...
