I'm trying to track down a leak in the tubing for my rear wiper sprayer. Everything in the rear door is fine. When I hit the sprayer, I can hear the pump whine and the arm moves. I get a little bit of fluid from the sprayer head on the arm, but I also get a whole lotta dripping from the passenger side in front of the rear bumper. I can't track the tubing forward from the wiper arm. It goes into the door, into the car and from there I don't know. I looked through the RAVE manual but can't seem to track it. Maybe I missed it? Wondering if anyone has a 'map' of the tubing so I can figure out where the leak is coming from.

Have you already remove the inner panel on the rear door? My best guess is either the hose has a hole in it somewhere inside the door, or the check valve inside the door is leaking. If you open the rear door, is the flexible rubber tube on the hinged side wet? That is where the door wiring and washer tube connect into the door.

 

Inside of the rear door is clean and dry. I just replaced the valve as I think the previous one was clogged but not I'm seeing wiper fluid dripping from under the car just in front of the rear bumper. I'm trying to trace the tubing as there's got to be a leak in it somewhere. Problem is, it looks like it's routed in the frame and I can't get to it.
