When I press either side of the wheel I can hear it making like a clicking/ticking noise but the horn just doesn't do anything. Where should I start looking? I did unbolt the horn off the car the other week but haven't tried using it since that :/ does it need to be grounded on the chassis or something?
Yes i think they need to be earthed ,and in the old days horns had an adjuster screw on ? not sure if the Copen one has might be worth a look
If that doesn't work this link might help - sometimes the electrical contacts corrode and need sanding down or replacing. https://www.copenworld.com/community/threads/horn-not-working.2427/
