Wiper settings - rear wiper on reverse?

[slipd]

Hi guys,

I've haven't had a proper play yet since getting my car back from the garage but I'm sure a setting or something has been changed/reset...

I'm used to my rear wiper automatically kicking in when I put the car in reverse (and it's raining) or when I've manually triggered the front wipers, like I did this AM because there was dew on the windscreen.

Is it a rain sensor setting somewhere?

Thanks!
