Horn stopped working!

As above. Found out on Saturday morning as I was leaving for FRL, and tried to pip the horn goodbye to my waving wife.



There is no current going to the horn via the steering wheel switches, but the horn sounds if the alarm is triggered (as Fil3638 found out when he tried to put something in the cabin on Saturday evening). Fog lights are working(I think, will check them tomorrow) as the switch light illuminates. Is it possible that there is a loose connection from the steering wheel switches perhaps?
