The Renault car does not come with a hot wired car horn. However, you can splice the wire and hot wire the horn yourself.
I used to have a replica on my pickup. All you have to do is have a hot wire that is connected to a aluxary switch to the horn. The horn must have a good mounting for a ground or a ground wire.
the horn has a ground and hot wire .usually only a hot wire because the horn body is grounded.it also has a horn relay.check the wires(wire)and check the relay.if these are good,the horn may be shot.this is all assuming the horn button or contacts at the steering wheel are good.
FIND THE HORN ITS USUALLY UNDER THE HOOD BY THE FRONT GRILL. THERE SHOULD ONLY BE ONE WIRE GOING TO IT ...HOT OR RED FOR POWER,THE GROUND IS PROVIDED BY THE HORN BEING ATTACHED TO THE CAR. POP OFF THE WIRE AND TAKE A LOSE PEACE OF WIRE AND TOUCH ONE END TO THE CONNECTION YOU JUST REMOVED THE WIRE FROM AND THE OTHER END TO THE POSITIVE TERMINAL OF THE BATTERY. IF IT BLOWS THE HORN THEN THE PROBLEM IS IN THE STEERING COLUME UNDER THE HORN CAP, SOMETHING UNDER THERE ISNT MAKEING CONTACT. IF IT DOESNT BLOW THE HORN THEN REPLACE THE HORN. GOOD LUCK!!!
Unhook your horn and hot wire it from the battery to see if it work. If only one wire is going to your horn that should be your hot wire so gound the negitive wire from the battery to your body.
normally the blue and red wires are hot white is standaed for nutral,
Relay problems or a floating hot wire.
Take the horn off and clean the mounting bracket then clean the bolt hole both with wire brush because that is how your horn is grounded. If that does not work you have a ground in your hot wire but first check the wire plug on the horn. If need be run new wire to a switch on your dash
sohunds like you have a short on the horn botton, you only have a hot wire, so when you push the horn botton it make a gorund to make the horn sound
