So here is the dilemma, I have no power to any wires running to my rear wiper. Switch on dash turns on pump and water sprays. Got another switch today and still no power on any of the 4 wires running to rear wiper motor. Everything did work until I had water over the motor ( can't say that killed it but I remember it working before).

Does anyone have a schematic that will allow me to trace where power should be coming from so I can start working my way through it. Fuse is good.
