Hi John,
Thanks for your response. I visually examined the connector and the in-situ associated socket on the board and they show no signs of staining or moisture ingress. I therefore assumed, rightly or wrongly, that this would tend to suggest that there has been no water ingress. I have attached some extracts from an associated thread from another jag forum which shows the type of socket staining indicative of water ingress.
I am just trying to establish whether I'm barking up the wrong tree by concentrating on the water ingress fault and should be looking at other potential causes which may be causing the inoperative wiper motor fault.
Thanks
Ted
