Whilst the car was parked up yesterday at work my headlamp wash wipe developed a mind of its own and ran continually until I finally had enough and pulled the battery after getting home.

looking at the wiring diagram I see that there is a fuse that powers everything before the relay so will be taking that out tonight to hopefully at least isolate the wash wipe system until I can get a better look at it. I'm assuming the relay is toast but I'm struggling to find any other than used via e-bay, which I'm not against using if I have to but with most second hand parts its a risk I'll end up doing it all over again.

other than main dealer does anyone know of a supplier?

believe the part is 61366904550

I am looking as well for my drivers side

pulled the fuse and everything is now still. contacted land rover and the relay is currently unavailable to order but the code is YWB000110 @ £69.47

just in case anyone needs one, thanks for the help all as usual

I just looked at JaguarLandRoverClassicParts and they are listing as in stock and available to order.

They seem to have a different set of parts availability to main dealer listing which always strikes me as odd.

Interesting... that diagram implies it's mounted in a fuse box with other relays, but I've seen on other forums / videos that you need to dismantle the left hand end of the dash including the vent & cup holder as the relay is mounted more or less to the bulkhead...more investigation required

incidentally the replay shown in the videos and on eBay are all a brown/orange colour

There is probably also a BMW part for an X5 or something (in the 2002 era) that is basically the same relay but half the price
