Does anyone know any common reason for Clio horns to stop working??

I have checked the fuses and that doesnt seem to fix it

Behind the nearside headlight is a plastic box that houses a few relays.Lift off the plastic cover & check the contact plate /sockets for water ingress & corrosion and even rotted wires.

hi

Checked the relay box, bone dry in there and doesnt appear to be any obvious corrosion.

Any other ideas?

Check the wires to the horn itself for corrosion. If OK, take the wires off, and run a lead (jump leads will do) to the horn itself straight off the battery. If it works, its a wiring/relay problem, if not get a new horn.
