About a month ago, my horn, brake lights and cruise control stopped working all together at the same time. NO BIG DEAL right!? Simple fuse blown. I checked all the fuses in all three fuse boxes. And I couldn't find even one burnt one. I didn't know the specific fuse that was connected to the horn, thats why I checked them all. I mean, It HAS to be the fuse, all the signs are their I mean, I know it's a very minor problem, but it's playing with my mind maaaaaaan (or is that the shrooms?) LOL. This is gonna bother me allllll night. Any help will be deeply needed. Thanks

 

It is #47 in the box under the hood (a 10A fuse). This will happen with aftermarket horns, and if that is the case I suggest you run a new circuit for the horn (see horn FAQ).

I hope you have not been driving without brake lights (btw, it also affects the ECM, ABS and cruise).

 

Ok, I just fixed it, thanks. It happened when I held the horn down for like 5 seconds, Freeway Blasters. Would it be better if I just put in a 20A? Thanks

 

I have those same horns and just doubled the fuse amperage. I've had this for almost a year, no problems but I've never leaned on the horn for that long.

 

What can I say? I was mad.
