Wipers doing their own thang!!!

[Simeon]

Hi All
My wife's 2004 K12 has auto sensing wipers and has recently been wiping the screen of their own accord even when switched off. When she starts the car they will randomly operate for 5 minutes or so then stop. I have read threads of washer pump short causing similar problems but the washers are fine. I did read a thread from a bloke who had the same problem and was fixed by changing fuse box under headlight. Now by the style of his reply, English was not his native tongue. Could anyone expand on this solution because it does'nt quite make sense to me.

Thanks

When turning on any device in a K12 you're actually talking to the computer via CANBUS which then turns on the wipers, lights or whatever, if any fault occurs it goes to fail safe and runs the wipers...

Joys of fly by wire eh?
