horn doesnt seem to be working on my s2, when you press switch on wheel you can hear relay clicking over but nothing happens.
had a look on my mates s2 and he appears to have 2 horns sitting next to eachother, whist i only have 1, could this be the reason why?

i have also tryed flicking it across the battery, and nothing happened, so am i right in guessing that the horn could be knackered?

much help appreciated, car needs to go for MOT and obvs wont pass without it
