Hi, I have an issue with my 2007 astra. The horn and the windscreen washer only work intermittently, and never at the same time. If the horn is working the washer isn't and the same the other way around. Does anyone have any ideas what might cause this?

I'd be checking the connections at the horn as its near the front and in all weathers. Same with the washer pump to start off with.
