So today I fixed my air con fault. My Haynes manual came today. Well that was a waste of time. There was no wiring diagram for the air con.
I knew the engine ecu would send a live feed to the air con pump. So I had a quick look at the big wiring loom that comes out of the way. I found the loom had rubbed through on the osf inner wheel arch.
You can see here where it's rubbed through the protective cover.

So since I searched for ages trying to find an answer i hope when some people GOOGLE the fault they find this page and I hope it will help some people out.
