L322 rear wiper motor

Until I saw the price of a new one I had to laugh at the design of the new shape RR's rear wiper. The screen wash tube which vents out of the hollow wiper drive arm had leaked and corroded the drive gear causing the plastic gear to strip out.

What kind of a half wit designs an electrical motor and gearbox and incorporates a washer through the guts of it?

Anyone got a second hand one for sale?

Got the same prob with mine
Mine leaks water out of where the hose connects to the motor
So its stained all of my parcel shelf now as the water ****es out when you wash the rear window

So just capped of the water spray for now until I can justify changing the whole motor !!

You can get a rebuild kit for them. I did mine (2007 Vogue SE) which was in a real state. You need the repair kit and a new rear wiper arm, job done. Takes about an hour.

Dealer part as a rebuild kit or is it aftermarket? Do you have a link please?

Was main dealer as I recall. It would have been mail order as all my bits are. Either Nick at Yeovil Land Rover or Dan at Duckworths. Can't put my hand to the receipt right now.

I'm actually surprised someone like Britpart hasn't done it yet. Just about all of these fail inside 3 years.

There's a good "how to" on the other site which is worth reading.

Yes, I have my 2005 RR booked in 7 November to have the rear wiper mechanism replaced (after a year without it working) because of ‘leaking’ (LR service centre I use has ordered the rebuild kit parts I believe and not a whole new mechanism) – I also took the thing apart myself and could not understand why any ‘designer’ would try to route/seal a pressurised water stream right through the middle of the thing and expect it to run trouble free into the car’s future. Crazy...

One other tip I found was to take the wiper arm off and slightly enlarge the washer nozzles with a small drill in a Dremel. It just makes the jets a little less likely to block up and cause the pressure to fill teh motor up with washer fluid. They're only the small brass ball things which can be adjusted with a pin so easily drillable.

Great, many thanks for the heads up! I came across a LR parts seller the other day that just sells by part no and carried a big inventory so probably a good place to start. Do you remember what the kit contained?

Asked all the usual suspects and a few more but no one had heard of a rebuild kit

nobody know of this rebuild kit then??

as i reckon i need one
infact my wiper just gets stuck half way, no water leak YET! but i reckon its gotta be todo with the plastic gear inside...

Pictured here is the stripped down rear washer / wiper motor from the 2002 L322 Range Rover - showing worn plastic gear teeth and rusted internals making this motor unserviceable and in need of complete replacement there being no individual component replacement parts readily available.

If you strip your motor - fairly easy job after pulling plastic cover off spindle and removing seven screws around body - you can inspect condition of plastic gears and decide if cleaning and re-greasing will get part moving freely again, so long as electric motor still works.

My rear wiper stopped working recently, also the washer. Removed the motor from the window, reasonably easy, I'd looked at the online video previously. Stripped and cleaned the motor as advised above and re-assembled with fresh grease. Tested on the bench - working fine. Back on the vehicle - rear wash / wipe restored! About two hours in total without hurrying and no special tools.
Not sure if I agree with the comments above about the design, seems OK to me. The water is a long way from the electric motor and just passes through the wiper spindle in a tube - quite elegant in my view.....I've just replaced one of the headlight wipers and washer pump and very similar set-up

I was going to recondition mine but looked at international sellers on eBay. Found one in the USA for £45 plus £15 postage. Fitted and been working well for months now.

I have a non RR with similar set up, hasn't scooshed for ages and thought it was bunged up, turns out it was only the bloody fuse, doh!
