How can I test a horn, the steering wheel button does not work, so before I tear apart the steering wheel I figured I would start with the horn...but how do I check it?

Easy. Connect one end to positive terminal from battery. Negative is chassis ground. Rotate screw post until you hear a rattle. That will determine that horn works. If so, simply trace wire back to steering wheel and fix!

That'll get you started. When you find the problem, let me know.

Or you wait til we drop the motor in, I bring my power probe and I fix your horn in about 5 minutes.

I got a fluke meter.

You have obviously never used a power probe. I have not picked my fluke up since I bought this bad boy.

Never heard of a power probe, and to be honest it kinda scares me.... :eek

I tested it like you said and got squat, tried the replacement horn and scared the crap outta myself. It was the horn, damn Toyota parts, damn things barely last 20 years.........Thanks Mid.

There's a screw or sometimes a tab that needs to be rotated that can make a non-op horn operational again...did you try that? I'd hate to think a damn horn won't last 20 years...I mean, how often do you actually use one?

This is correct. I've revived many horns this way.
