I swapped out the horn for a set of mini air horns on my '03 TJ. Press and it worked. Press again and it briefly worked and now nothing at all.
I've checked all the fuses (inside the glove box and under the hood) and replaced the horn relay for good measure and still nothing. Also wired the horn directly to the battery to ensure it works.
Does anybody know if there is maybe a secondary fuse or relay I should track down?
