The switch HAS TO BE GROUNDED TO THE DASH.. The yellow wire is hot with the ignition switch in the ON position.. If there is no voltage present on the yellow wire, there is an open (as opposed to a short) or bad connection somewhere.. Find the open, (don't forget the fuse and it's connections) repair it, and the wiper motor should work..

Good info. The wiper is hot all the time. The dash switch makes ground for it to work. You have to have the wiper switch grounded to the dash for it to work.
