Horn not working, alternatives?

Get a bullhorn and scream at the people in front of you instead of honking.

If Joe's idea doesn't work for the inspection :

There's a horn relay in the engine compartment fusebox. Lift the relay up a hair and get your meter lead on the terminals. Look for two constant 12 volt terminals. Then when the horn button is depressed, look for a ground signal from the horn to the relay, and then another 12 volt reading on the (last) terminal.

If you have all that, the issue is the horn(s) it/themselves. Make sure they're properly grounded and that 12 volts is reaching them when the horn button is depressed.

Often times, the issue is with the horn-pad adjustment. If this is the case, you will not get that ground signal to the relay, nor a 12 volt reading on the last horn relay terminal.

Also don't forget the fuse as well. It's not uncommon at all for the horns to develop an internal short.

Good luck.

I've seen a lot of people around here use their middle finger as an alternative.

When I had my truck with a PA system it seemed to work fine. it was actually alot more effective than any horn could ever be. Effective in pissing people off.

But if you need a horn just to pass inspection then just get a horn and wire it to a momentary switch and when they tell you to honk your horn, just press the button.
