L322 Rear wiper motor

Good one. I am just looking for one myself and the prices are ridiculous. I am pretty useless at home-maintenance?! How difficult was this fix? Really do not want to pay £400 to replace my rear wiper?!

Changing over the park magnet is the tricky bit. If you are not bothered if the wiper parks on the other side of the swept area all you need to do is remove the original motor, change over the cover / mounting bracket to the "new" motor and refit. Run the motor without the wiper arm fitted to park it (observing parking position) and refit the arm. Don't tighten the nut holding the arm fully, this will allow the spline to slip, allowing you to move the arm to exactly where you want it after you run the motor with the arm fitted for the first time. Fully tighten the nut when your happy with the position of the swept area.
Good luck.

I have a 2004 Range Rover L322 TD6. The rear wiper motor failed a few months ago, so I took it apart to see if it could be fixed. Unfortunately it was quite badly corroded due to water ingress from the washer system. Could not find a new unit anywhere. Had a look on ebay to try and find a replacement only to see sellers trying to get between £300.00 and £400.00 for a second hand part (which might still be leaking internally). As many of you may know the early L322 electrics are based on the BMW E39 5 Series, this led me to think that some of the electrical components are probably similar to other BMW models of this period. Sure enough after some research, I found that the rear wiper motor dimensions and connections are the same as the E46 3 Series Compact, which was much easier to obtain. The mounting bracket / gear cover however is different but this can easily be swapped over. Before refitting the original cover, I replaced the o-ring that sits inside the plastic water inlet where the wiper spindle locates . After refitting to the vehicle and trying it out I found the wiper parked to the right instead of correctly parking to the left, otherwise it worked fine. There is a magnet in the internal plastic gear which I moved 180 deg to the unused opposite slot to correct this problem. The magnet must be installed in the in the same directional orientation as it was in the original opposite slot as the pick up is sensitive to magnet polarity. Best to mark it in some way before refitting and gluing in place. If you get it wrong (as I did) the wiper will stop randomly when switched off and strangely the rear washer won't work either. This repair cost me £90.00 (cost of the used part from ebay). Hope this may help some of you with the same problem.

This is an aftermarket non Bosch motor. There's a good chance that you're cover / mounting bracket won't fit.

This is not an urgent fix unless your mot is due, so its worth waiting and watching for reasonably priced units to appear. I sourced a second hand motor in fantastic condition from an eBay seller in the States..cost me £90 inc postage. Fitted it yesterday, v straight forward job which took 40mins max. The blade sits top left hidden underneath the spoiler exactly as the original did and works perfectly inc. the washer obviously. I found the x3 how to vids from Powerfuluk during the initial google search process. Agreed, satisfying cost effective fix - which is rare.

I also have a spaniel. Is yours a springer? My Mabel is a field spaniel....

She's beautiful, rare to have full liver with the white chest strip. Mine are the show type springers, same amazing nose sense as the workers but far less hectic and busy. Still love a ball though so highly trainable.
Field or Show, I love the breed, fabulous dogs.
