Horn wont work

[TooneySonic]

Very strange, has the wire corroded possibly?

Have a play with the connections. My girlfriend's clio's horn stopped working when it went in for its MOT. The garage just cleaned up the connections and now it works fine.

check the wiring first often its corroded on the clamps, maybe spray some WD40 on it

volt meter on the connection,

if it shows nothing, then check fuses and wiring,

if it shows 12v then get a new horn.

it will most likely be the earth connection as it has happened on every clio I've ever known... as above check fuses, then try cleaning up the connections but before you go & buy a new one run a wire directly to the battery & another to an earth to check if it works.
