Rear Windscreen Wiper

[JDM34]

Hey guys, I just got my R34 GT and took it in for a service. My mechanic noticed when you turn the rear windscreen wiper on, it leaks water into the boot. We are thinking that the hose at the back has been snipped by accident. The thing is it only leaks when it's running (I never even use that wiper anyway) but is fine otherwise. I'm wondering... how would I actually be able to get to the little hose at the back there, and just fix it up so it doesn't leak when it's running?

Wouldn't I have to remove the three screws at the back, then take the speakers out and work from there to get to the little hose?

Cheers guys.

I would be inclined to go from the boot and keep tracing it back to the source, when u do find the split/cut don't just tape it, wiper squirter pumps have great pressure and it will just work it's way out, new Holden captiva's always do this when you drop the headlining, best fix is to cut it fully and use the correct size joiner with some silicone to be sure
