Might be a bit of a funny one, but what should be under the cap on the rear wiper. Mine just trickles out so I took it off to investigate, is there supposed to be a washer jet under there or something? I took a couple of pics to show you what I mean.
I tried the washer with the cap off and it squirted out nice and easy, just when I put the cap back on its feeble to be fair.
