just done this, very easy...start by taking of the cover inside the tail gate,it covers the wiper motor.. you will see the water feed connecting to the wiper motor, in that short length of black pipe there will be a small one way filter. check there first, disconnect and see if you are getting water upto the filter, run it for a while to clear the line,clean or replace the filter, remove the pipe from the base or the wiper to make sure you are now getting water to wiper, if you are but still not out if the wiper arm you will have to go to the next step...

Mine isn't spraying water - I can hear the motor run when I push on the stalk, but it doesn't run continuously. More an intermittent sound of the motor running. Front works fine though. |

I've just done the "clean-out" process described by daveo above and found the wiper arm feed blocked with crap. After cleaning it out I put a bucket under the pipe and tested the water flow before putting it all back together, but even now, it takes a while for the water to eventually come through. But at least it works! Cheers

noddy, the rear washer does not run all the time, whn you push the stalk the wiper starts ans you will get 3 bursts of the water pump about a second apart. follow step 1 and disconnect at the filter ti see if you get a flow of water,if not you neen to back to the washer bottle..

check the one way valve, thats put there to stop the water drainig back and doing what you discribe, you should only be able to suck or blow one way, there is a direction of flow on the filter V8 facelift Range Rover Autobiography 22" wheels. 1976 Harley Davidson Iron Head Sportster |

I replaced the non return valve but it still takes a few wipes of the wiper before any fluid reaches the rear window. After i've used it a couple of times it's then instant..... Stolen / Gone: 2006MY Supercharged LPG Autobiography - Zambezi Silver with Sand/Jet/Jet Oxford Leather..... |

I carefully removed the black plastic cap which houses the washer jets.

This is a guess around the one way valve... but I reckon you will be able to get something that is comparable to anything that a dealer would give you from an aquatics store... or a quick search on ebay reveals a lot....

Same issue. Jets in wiper arm clogged and rusted so I bought new arm and did clean out. All working now. Be careful when you take wiper arm off as small plastic piece that goes from water feed to wiper arm pings off and disappears into the great hole all small things go to.
