Hi All,
My apologies for late reply I have been very busy. Yesterday I took the car for MOT it passed it without any advisory : ).
As promised please find attached the information I found that helped me to pin point the fuse that I needed to changed. In the first wiring diagram that I shared with you before, it pointed me to the gauge fuse which I couldn’t find anywhere. This new diagram pointed me to the wiper fuse and the description where it was located in my fuse box matched nicely with the new information so it was straightforward switch. Many thanks for all your help and interest.
I also added some pictures from the MOT test.
All the best
