Thanks for the question
The horn fuse is Fuse #3 in the relay center.
The engine compartment relay center is located on the right side of the firewall, under a plastic cover.
The interior relay center is located behind the right side of the dash.
There is also a fuse block located behind the left side of the dash.
Here is a diagram of all these locations...
I hope this helps.
Then I recommend getting a test lamp and going one by one, touch each of the fuses to make sure there is power on both sides of the fuse. Do this in the left and right interior fuse centers and under the hood as well.
Grounding out that wire would have blown a fuse. That would be the reason for the pop noise. I doubt that a relay was damaged by this.
That does not make any since to me. We are missing something here. This horn circuit is really easy and short. If all the fuses are good, then something else shorted out or a wire may have melted somewhere, which would be hard to trace.
The only other thng I can suggest is to trace the wiring the best you can and if needed, run a new circuit with new wiring and its own fuse holder.
The horns are wired in paralle, you can just branch off one green wire to run to both.
The 2 orange wires at the realy are the power supply. You can run a new power wire and splice into the orange wires. This will give you power to the relay. That will bypass any factory fuse, just install a new inline fuse holder.
The black wire on the relay comes from the horn button
The green wire runs to the horns.
The black wire on the horns just attaches to a metal ground, in this case it should be above each horn.
Thats correct, you could do that. Also, depress and turn the plastic peice around the red wire going into the column. The will release that wire. Press the horn button and check for continuity between that red wire and the ground. This will check the horn switch.
** be very carfull removeing that red wire. Turn the plastic peice very lightly. There is a little tab that locks into a grove and can break really easy. Just push down a little and turn it to the right.
Please keep me up to date.
Place your VOM on one of the orange wires at the relay and to ground to see if there is 12 at the relay, check both orange wires this way.
Then at the relay, place one terminal from the VOM on the green wire and the other terminal on the green wire at the horn. This will tell you if there is an open circuit.
Then place one VOM terminal from the horn switch and if it will reach, the other end on the black wire at the relay. Have someone press the horn button to check for an open there.
Doing this test should narrow down which wire is having the problem.
Keep me posted.
That 60 amp fuse is not the correct one. There should be a single, small fuse listed as "#3". It is a 15 amp fuse. The 60 amp just supplies the power to the other fuse ( locks, trunk and horn fuses). The horn fuse will be located in the interior fuse box, on the driver side under the dash.
However, to just get the horns working, run a 12 volt wire to both orange wires right at the horn relay. Cut the wires from the relay leaving about 6 inches of wire to play with, then connect the new 12 volt wire there. You will have to add an inline fuse for those new wires you run to the horn relay.
Unfortunatly, there is no easy way to remove the fuse box. The only thing I would suggest before adding wire, is for you or someone else to pull 1 fuse at a time, check it and move on to the next one.
Like I said, there is a fuse somewhere in that fuse block, the passenger side fuse block or the one under the hood that is blown. There has to be.
I'll be here to help.
You can actually skip the VOM and just look through them using a flash light, you will see if the metal peice in the middle has broken, or blown.
Thank you very much.
You are more than welcome, I hope you get it taken care of.
To answer you questions,
1. Yes, you can just cut the wire going to the factory horn button, and branch it off to your own switch.
2. Your question is showing a value of $9.00, if you wish to make it $30.00, which I would greatly appreciate, then you would do this by adding a $21.00 bonus after you hit the accept button. I am not sure where the "Add bonus" is. It should be on either the accept page or the feedback page.
Once again Brent, thank you for your patience working with me and your situation. If you need help in the future, ask for me by name in your topic heading.
