As it's now officially winter I thought I'd sort my wipers out starting at the relay as its the easiest lol from doing a wee bit of research it turns out relay 377 is the wiper relay and its under the dash to the right of the steering wheel. Its not on my car!
I had a good look myself and just to check I'm not a retard mark had a look when I was at b5 and its just not there. Just wondering if anyone had any similar experiences or possibly etka to see if my old girl has a different number relay?!
