It is not advisable to install a car horn without a relay. The current draw of a horn is too much to run directly through the car and horn switch. Relays are used on items that have a high current draw for this reason. It is an unsafe practice to not use a relay in these conditions. You would not want to catch your car on fire.
The wire to the relay grounded somewhere. Take it to a garage to get it checked out.
A good way to fine the horn relay if you dont have a manual is to pull the wire on the horn then have somewon press the horn button .... beep beep beep you will hear a clicking sound which will help you locate the relay
The wiring for the horn goes from the horn to the relay then to a box located unde the dash which in turn connects to your horn pad on the wheel in the car
if its not the alarm malfunctioning, there is a short circuit somewhere between the switch/battery/relay and the horn its self - youll have to find the short and insulate the wire or replace the switch.
check power to horn - no power to horn -check ground -no power to horn -check relay - no power to relay -check fuse inside car first thing -still no power to relay -check horn button -still no power - possible break in wire
The Renault car does not come with a hot wired car horn. However, you can splice the wire and hot wire the horn yourself.
the horn does not have a relay on your car, does have a fuse inside the car, d.s dash
The horn relay is located in the fuse box under the hood of the 2007 Chevy Tahoe. The horn relay is responsible for making the car horn have sound.
To wire up a car horn with a button you first need to run one of the wires from the horn to the battery. Take 1of the wires from the horn and run it to where you want the button to go. Connect the wire to the button and that's it.
The relay block is inside the car, passenger side on kick panel up by the glove box. Horn relay will be the square block in a row of 6, closest to the firewall.
The easiest two ways are to either remove the fuse, or remove the relay. If the horn is stuck blowing then the relay is probably bad.
The horn switch or relay.Your ignition switch does not power up the horn switch or relay,the switch and relay have constant power to them at all times as long as the battery is hooked up.I would start with checking the relay and then go to the switch. Also, check the wire under the steering wheel cover. If this wire is gounding out it will case the horn to blow Probably moisture in the horn circuit. The horn is always hot. The circuit is made by completing a ground. This way, several different circuits can energize the horn easily, i.e., the car's alarm, which it may or may not have. Moisture bridging a certain wire/terminal with the chassis will make the horn blow. Brake lights are probably wired the same way. They can come on without pressing the pedal. Completing grounds to turn things on makes them easier to control with the car's computer. Pull fuse until it dries, then park in a more sheltered area.
