Replacing rear hatch struts, windshield wiper doesn't work, no broken wires, what now

? (there wasn't enough space for a question mark in the title, so there you go... haha)

Mom's '03 wagon is getting new rear hatch struts, and while it's apart I was hoping to see some obvious damage to the wiring looms by the hinges to explain why the rear windshield wiper isn't working. The wires all look pristine so now I'm kind of at a loss what to look for next. What color wires are responsible for the windshield wiper motor? If I knew this I could at least start tracing them for opens or shorts.

Any other ideas? Her windshield washer fluid was leaking out of the tank behind the left front wheel and I recently swapped out the little pump mechanism to fix this. Is there anything in that area that could affect the wiper motor issue?

Looks like the issue is up front at the reservoir. I don't think I hooked up both pumps because the rear one was the cause of the leak. Time to go jack her up and pull the front wheel.
