The wipers will only work when at the highest setting on the switch. And even then, it seems to be at the slowest speed (or at least very slow). The intermittent and low setting do not operate the wipers, and the fluid will not work. I do not hear anything trying to operate either except in the high setting.
I think you need to replace the intermittent wiper module. Should be available at Autozone or Napa. Not sure of its location on your car, but should be on the firewall.
