There are a couple of possibilities here. The first is you have an internal short to power in your vehicle's Rear Wiper Control Unit or you have a short to power in black/blue wire going from pin #1 of the Rear Wiper Control Unit to the Rear Wiper Motor. I would start by checking the black/blue wire for a short to power. In the diagrams down below I have included wiring diagrams, connector views, and the location of the Rear Wiper Control Unit and the Rear Wiper Motor, as well as a guide for how to find a short to power. Please go through these guides and get back to us with what you are able to find out.
