So my first problem in a while. The front wipers work. The front and rear washer jets don't, and the rear wiper doesn't work either. As I was going to AKS for a six month service, I asked Chris to have a look at it.
It wasn't the pump as a swap with another one made no difference. Then Chris checked the relay and said the contacts were corroded. After being cleaned up, the washer jets worked, as did the rear wiped.
Until yesterday when it all stopped working again.
Does anyone know where the wiper relay is?
