Ill be honest me and my mini have nearly come to blows a couple of times , like atm there is a wireing problem (which considering i only had it MOD'd last week is a little odd) and everytime i got over a bump in the road my power to ym window wipers and indicators goes which is a little fustrating and then a few bumps later it comes back. Looks like my weekend schedual has just filled up. Dam wiper motor is on its way out as well ! :S
sounds like a dodgy connection somewhere try your fuses!
