Thanks for the feedback. Took the switch out and gave it a bit of a beating and I can get it to work now. No doubt they will want the equivalent of £50 here in Mexico, since they wanted £100 for just one of the pair of horns. How can they justify the price for a 5 bob switch that, it seems, doesn't even work in alot of cases? I've never even used the hazards, except to check that they work.
