A friend of mine has a 07 mk5 golf. The blowers/ windscreen wash / rear wiper and wash have packed up , he was told it is likely to be a ' b9 relay ' Does anybody know anything about this sort of thing ? I tried to help and got him a part we suspected it to be but that hasn't worked, he's got it in shop tomorrow but just asking in case anyone has any ideas and can save him a bit of time / cash!
Thanks in advance , Chris
