could be either. or a fuse.
It could be the relay or the fuse or the horn itself. Or, it could be all three!
the horn relay switch is in the fuse panel or it should be on the horn wires itself
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.
The relay is mounted to the horn itself under front bumper
check the horn relay or the horn itself!
It is important to know what is causing problems in a car. When the horn relay clicks, but the horn does not sound, it is not a fuse but more likely to be the cars clock spring.
Start by checking the fuse panel for a blown horn fuse in the fusebox. If it is good, move on to the horn button and relay. The easy way to see if these are working properly, turn the key to "on." There is a horn relay, probably in the fuse box. Push the horn button and listen to the relay for a "clicking" sound. If there is a clicking sound when you push the button, these two should be ok. This should narrow the problem down to the horn itself. I have owned two dodge vehicles and have had to replace a horn on each of them and this was how I determined that it was the horn and not other circuitry.
You have to determine the cause first. Check the horn switch and contacts, fuse, relay and the horn itself.
well, check all the fuses and check the horn relay if not work. if horn relay sound but horn not working, then you will have to check the clock spring for loose connection or tighting it.you can even look for bad wiring connection to the horn system.
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
where is the horn relay on my 1993 Mercury Sable located
Short in wiring or a defective horn relay or switch.
