Kevin, good point on the grounding. I put a ground wire on the wiper motor, to no avail. I'll do the same on the wiper switch to see if that makes a difference. As noted, I have power at the wiper motor (all three leads). I just checked for power at the switch and found the center and right wires (one light blue, the other black) both have 12 volts, but the far left wire (dark blue) did not have any power. Do you know if that wire (far left dark blue) is for the washer or the wiper? I don't really care if I have a washer at this point, but if it's for the wiper, then it's part of the problem. I'm guessing the far left wire goes to the washer, correct?
