Rear wiper/washer problem

Hi and thanks for using 2CarPros.

By any chance, could you have opened the hatch beyond it normal limits damaging the wiring or causing something to come loose?

I checked a wiring schematic, and the ground is under the hood in the engine compartment. Have you checked to see if there was power to the components? You can do it with a simple test light. That is where I would start. Here are some links you may find helpful for testing:
