Hi I own a tired out 2005 Legacy outback and the rear wiper quit working this last winter so I decided I would take on the challenge. First found none of the fuses were blown then went back opened the hatch and closed it the rear wiper moved to the oppisite side and stopped never to move again, A quick class at "University of Youtube" showed the most common issue is wiring issues with these models is at the rubber boot piece next to the hinge on the Right side. So I removed the boot and found a previous repair splice to the yellow green wire had failed. I thought I had found my problem. I realised that putting the repir splice right at the failure point was not a good plan, so I removed enough interior trim to get to the harness and unplugged it down by the Right tail llight. I pulled both end of the wires down enough to get to them and to get some slack I had to cut the electrical tape in the lower right lower corner of the window in order to free up the wire harness I needed as it was wrapped into a bunch of other wire looms that were not involved. I decided to fix it properly this time and not place the repair splices at the failure point again. so I replaced the butt splice on the hatch lid side but then added shrink wrap to the wires on each side then a second shrink wrap layer over everything to help releive some of the wire stress and keep it from chafing or cutting again. I then snaked a safety wire through the boot so I could later pull the wires back through. I then added a generous length of new wire to the hatch side, shrank up all the shink wraps and pulled it all back through the boot into the ceiling of the car. Once I had me new wire fully down into the head liner, I spliced the yellew green wire and did the same supportive shrink wrap on those ends too. So niether of the splices are anywhere near where the wire bends and flexes anymore. That is all new wire clear through the boot. I protected the new wire with shrink wrap to keep it protected this worked very well. Much better solution than working right there in the limited space inside the boot like they did the first time. So I now had 12 volts to the motor via the yellow blue wire again. But it still does not work Looks like the yellow blue is the power in and the black ground wire comes out of the motor and stays black back into the harness is ground for sure. Can anyone confirm the yellow blue wire is power for the wiper? My car has 4 wires at the plug for the motor, not three as I have seen in the drawings. I ohmed out the motor between the YB 12 volt power wire terminal and the black ground terminal and show an open. So I suspect the motor is shot as well. I ordered a new one today and will report back. I hope this repair helps you when it happens to your gen 3 and it will given time. It is a better repair. it moves both splices out of the hinge area, and much easier to access things.. My door side splice is up inside the hatch framework now where it ddoesnt move and the lower one is on top of the head liner, where it also will never move. BTW you do not need to remove all those panels from the rear seat back like the one YT video showed. I was able to get the the plugs behind the tail light by just removing the aft pillar covering and the screws on the side panel I had just enough room to get in there and pull the entire plug out to where I could reach it.
