There's a wiring diagram in this post that should be applicable to your 06.im pretty sure my rear wiper motor is dead but i want to test the wiring first, i know ive seen in multiple threads a link to the rear wiring diagram but now im having issues finding it, sifting through the pages and using the search bar, i feel bad for asking cause i know its here but could somebody please direct me to it? thank you in advance
Does the rear washer pump work? If it doesn't then fuse #23 might be blown. That, I believe, would disable the wiper motor as well.
The most likely wiring problem is in the harness going from the car to the hatch. In the wiring diagram, it's the wiring that goes from connector D35 to the rear wiper motor. There's only four wires in that harness related to the wiper.
The harness connectors (including D35) are in the cargo area, right side, slightly below the "D" pillar. The cargo area right side trim panel might have to be removed to gain access to the connector. (The other ends of the related wires are at connector D43 to the wiper motor.)
If you suspect the wiper motor, it can be checked at connector D43. There should be continuity between pin 2 and body ground.
