Hey guys. So, I changed my pads and rotors today. I'll tell you what, it was so much easier than I thought it was going to be. Hopefully I seated my pads and rotors properly. Started out at 10mph to full stop, then 20-stop, 30-stop, 40-stop, and finally 50-stop. I followed it up with hard braking all the way home, probably a total of 10 stop signs and lights. Not the problem I'm having though...

I replaced my horn. I got rid of that crappy stock horn and replaced it with the Wolo Bad boy air horn. I did EVERYTHING to the T. I moved the stock wire from the horn (assuming it's the (+) wire) to the (+) on the wolo motor. I then grounded the (-) terminal on the wolo to the crossbeam of the car behind the bumper. I mounted the wolo directly under the stock air box, it was the most convenient (not easiest) place to mount it. I gave it a test honk, and it worked fine at the garage. Headed home... gave it another test honk... it gave a .75 sec beep then nothing. After that, it would honk at all.

I don't know if it shorted, I don't know if the wires need to be swapped. I'm completely clueless. I'm stumped so bad it hurts. I'll be even more pissed if I have to go and remove the whole thing.

Guys, if any of you are considering swapping your horn, for the love of god just remove the bumper, it might be a pain, but it's so much easier than popping those stupid plastic things out of the bottom and dealing with the intercooler and radiator piping, not to mention the wiring.

 

The horn is a simple circuit. First check the horn fuse. Then make sure you have power going to the horn then double check the ground. You do have a volt meter or test light right? If you have + and - then maybe the horn took a crap. Swap in your stock horn to double check.

 

Here's some possible things I can think of:

1) A wiring came loose.
2) A part of the exposed positive wire came into contact with a bare metal.
3) The horn could be drawing too much power, causing a fuse to blow. Stock horns are usually wimpy and uses a lower AMP fuse. Air horns use a slightly higher AMP fuse.
4) You bought a faulty air horn.

 

All of these are really good. I would go with number 3 first. Check the fuse. Since you are running a bigger horn it could have easily blown it. Just get a bigger amp fuse.

 

you did something wrong, just re-install
