Rear wiper
Morning all, the rear wiper on my swb has all of a sudden lost it's auto cut off, so when you turn the wiper off it just stops, it doesn't return to its normal position, also when you turn the intermittent switch on it runs continually, any advice. Thanks
Hi Spike
Two options for me, one easy to check one not so...
The front and rear wipers are both controlled by separate relays under the drivers side behind the fuse board
The relays are both identical so you could swap them over and see if the fault moves to the front
Failing that there is a mechanism in the motor that tells the relay when it is in the park position and to shut off
This could be broken, dirty etc not too easy to sort but a careful strip may reveal it, depends how much it bugs you!
Used motors on eBay come up on eBay for around £40 ish from time to time

You got the Bosch number off any of the motors?
OK...Maybe..

I am open to correction here but I am pretty sure the wiper is parked by the relay, not by a groove or whatever at the motor.
I hope I haven't just shot my street cred

I wish you were right... and I am definitely not in a position to offer 'better advice' but to date I have replaced the switch, relay (both OEM Thanks Gav) and installed a second hand wiper motor - to no avail :-). The last thought from the guys at the garage I use - who get used by most of the main dealers to sort electrical gremlins out - so don't get them started on JLR kit - is that the cut out 'should' be controlled by a grove on the motor (as per front ones) but it could be a diode on the motor that gets burnt out over time. I will say when I first opened the motor cover on the original motor it looked like it had been in about a week!! So I'm not sure as motors go they have a hard life, so I still remain dubious about the whole 'groove filled in, diode burnt out' thought, but I know squat about car electrics (ironical really as I bought the 460 to avoid electrical issues :-)) The only other info I can offer which relates to mine is that the fault seemed to coincide with a lot of bodywork during which they trailed the perm live from the rear door loom onto bare metal and fried a good bit of the rear loom, which had to be replaced (by an auto electrician) so unless he did something to mess up things between the relay and the motor?? All in all.. still thinking of getting a proper new motor :-) Simon

sounds like you need a new stick on the steering column
Hi all, a bit late I know but recently my front wipers also lost both of the first two stages when switched on, (no intermittent no normal speed and no wipers when you push the screen wash, however they work on high speed but also have no park so they stop whenever you turn them off, I could live with rear one but the front are a real pain. I managed to get hold of two new wiper relays Bosch part number 0 335 320 015, they are the same for front and rear and today changed them both, (one of them not easy) it made absolutely no difference whatsoever to either front or rear!!
