My MK7 horn has stopped working, or at least partly. There was a mk6 horn in the van which i've replaced with an original for a MK7.
The fuse was blown which I replaced but now the horn does not work from the steering wheel, and I can't hear any relays like the horn is attempting to work.
When I lock the van via central locking, the horn does beep, so I know that it's not a fuse as it is working.
I'm thinking of the steering wheel squib being the culprit here, although oddly the cruise control functions are working from the wheel.
I removed the airbag and joined the two wires in the wheel but no joy. Before I fork out for a replacement squib, does anyone know what wires in the two sockets that connect to the squib are for the horn. I want to short them there to see if the horn does work so I can be sure it's a squib that I need.
Thanks
