It's not passing fluid so can't clean back window. But my main concern was the floor behind the driver's seat is soaking wet, my partner thought that if my back washer wasn't working then it could be leaking causing the soaked carpet, but if the washer runs along passenger side then it's obviously not that!? Thanks for the reply!
Usually the rear washer issue is between the hatch and car body. There's a concertina rubber hose at the top of the hatch. The wiring and the hose usually fail inside that
Don't know whether that means the water would then run through the boot and into the rear floor though
