Hoping someone can help. My wipers work, but my washer
doesn’t. I disconnected the washer motor to check continuity of the harness to the switch but no luck. Nothing when engaging the switch. I then removed the switch and checked continuity from harness to motor.. no luck. All contacts looked pretty clean so I’m thinkin maybe a break in the circuit. Also noticed I have zenki dash/engine harness with Kouki wiper motor. Not sure if that matters though. I also tried to install a spare switch just to see but washer still didn’t work.

Side note. When you push the washer button does it trigger wipers and washer simultaneously?

Update: turns out I had a kouki dash harness installed with my zenki engine harness. The front/rear washer motor wires at JB4 we’re swapped. Re-pinned the corresponding plug, and fixed the issue. Figured I would update just in case anyone finds themselves in the same situation.
