I always test them by hooking direct to the battery also. I've had to replace a lot of horns on various cars over the years, even fairly late models, so they do go bad. I even bought a new purple Road Runner horn that won't work. Too bad I didn't try it when I first bought it, I'd had it about 4 years when I finally got around to using it. Kind of late to ask for a refund.  I haven't figured out how to repair them. Dallas

There was a post on here recently where a guy washed his and got water in them. Long story short, it is very, very easy to take them apart and sand the contacts inside. there is really not that much to them. They are very simple.

Ive found that if you tap them and use direct batt they will usually start to work.Some you also have to adjust the screw on them.Ive also shot some WD 40 into some and then tap on them.Rocky

and out of the four none work when hooked up to a battery. Is there a different way you should test them?
If it has a small tone adjusting knob on the side turn it slightly back and forth from center
 That has worked for me before too.

I put the screw for the mounting braket on the negative terminal and then a test light to the positive terminal and the light lit up, but no horn. So it was making a connection... I think I'll try some PB blaster and if that doesn't work tear them apart as in the link. Thanks all.
The test light did not make a good connection.Use a jumper wire instead.The test light checked for a complete circuit.You did not have battery power at the horn.The horn on ground lug is good.+ connection was not. A fused jumper wire would be best.But any wire will work.Yes you will get a slight arc when connected.don't use phone line thin wire neither.

Exactly, if the screw is too loose, or too tight, the horn cant vibrate and no sound. This is one of the more obnoxious things you can do in your garage. Shooting guns is another but I digress.
