Well its a bit strange really, i was driving down the A25 cruising, didnt touch anything (except for the steering wheel ) and my wipers came on and did a single sweep of the screen and returned to the flat positon. was quite weird. they still work as normal and hasnt happened since.
i know fiat wirings have a reputation for being unconventional, but...

i did smile at it.

It might be the start of electrical problems, i had something similar, ended up with a new fuse box
