Hi all, wanted to share my solution to the dreaded rear screen wash leaking out of the wiper motor body. Having tried, unsuccessfully, on both my L322’s to fix leaking from this grossly over engineered system of delivering fluid to the rear window without spending £100+ on a new motor I have installed what LR should have in the first place - A SCREEN WASH JET. Cost £5.00 see pics. Next job, fix the reversing camera (Dash Cam with rear view I think).
Cheers Tricky. :)

Bloody hell, I didn't know my L322 even had a rear screen wash! Of course it doesn't work, is the water sent from the front of the vehicle or is there some other 'fiendish' device for the rear?

mine doesnt work either, does that mean its leaking when I try it? 🤔😅
 
Tricky of York has an absolutely elegant solution, which should (of course) have been the original design. But oh no, they give the design to the lad (or lass)who has a new drawing board and a sparkling new degree in mechanical engineering and he (or she) comes up with an amazingly elegant design, which of course will work for the first year or two and then fail.
My solution is rather less elegant than ToY's.
I took the inlet port off the back of the motor. That wasn't too difficult because it had pretty much fallen off anyway.
Then I got about 50mm of 12mm od plastic tube rammed it onto the spindle and put a clip round it.
Then I pushed the original rubber hose up the inside of the plastic pipe.
Of course the 12mm pipe rotates when the wiper is swishing so the rubber hose is flexing. But I've every confidence that it'll last every bit as long as the original design.

BTW, the it's a common washer tank in the engine bay. It has 3 pumps (all interchangeable I think) for the front screen, headlights and rear screen

Our headlamp washers don't work either....someone obviously thought they wold fix them sometime but gave up due to the complexity of the original design! Now I know I am 'not alone' I shall endevour to fix BOTH rear washer and front head light washers...will keep forum posted of technique and hopefully positive outcome.
 
Remember, the headlight washers only work if the headlights are on and there's enough fluid in the washer tank. Also, they only squirt every 5 (I think) flicks of the washer switch. If I remember correctly, the left (passenger side) does some of this figuring out and controls the right side.

You’re really getting into this aren’t you. Your assessment of the whole system seems correct to me. If anyone is experiencing a lack of washer fluid out the rear jet then work back by checking the jets are clear then for leaks into the motor housing. If that’s all dry then the non-return valve in line and then the feed pipe all the way to the front. It could be the motor to the back has a fault or if it runs then a split pipe could be delivering fluid inside the car. It’s a great way to spend a weekend….:oops:
Cheers Tricky :cool:
 
Thanks to previous replies I now have WORKING front head lamp washers, I had no idea the headlights needed to be switched on first! With renewed vigour I shall set about getting the rear washer working tomorrow.
Not tonight though, because I am off down to East London to take in the West Ham open top bus parade and will be partaking in one or two sherbets if not more!

Spare a thought for all passengers who've innocently gone before you in a hard-top only to end up with a driver who hasn't a clue how to play bridge.

Getting into it you say!

Several weeks and a couple of headlight washer motors later .... and even then I had to introduce an additional relay into the washer system for reasons even I (a chartered electrical engineer) don't fully understand!

West who?
 
Did mine in January with twin jets but wasn't happy with the jets direction so bought some different jets to spray across the window instead of down.

New jet. Had to trim the clip of to make it fit better.
