Basically my jdm ef7 horn doesnt work, I guess I never tested it when I bought it 2 weeks ago, but I got a fresh battery in and it doesnt work.

Ive got the front bumper off and I can see 2 horns mounted on the front, both look different, and the wiring on them is secure and clean, and I also checked the underhood fuse box and the horn fuse is good.

Any suggestions on how to diagnose?

I kind of want to hear it but I also think its going to sound "meep meep" wussy like and I'll just want to upgrade it anyways. Are there any cheap nice sounding upgrades for horns out there?

Hoping to get this nailed down before I get the bumpers back on.

Thanks guys

 

Check for voltage at the horn terminals when the button is pressed. If no voltage, probably either an open in the harness somewhere, or the switch is bad. Check for voltage at the fuse, and then look at the switch.

BTW, my JDM EF7 has a pretty (stock AFAIK) mean sounding horn.

 

I tried touching the horn right to positive negative and it didnt make noise

I will check for voltage going to it though

 

nobody does any easy upgrades?
