Horn Inop
My horn no longer works. I push on the horn pad and nothing. The
corvette service manual instructs one to check connections, check for
defective relay (I replaced it and you only hear the relay click when you push on the horn pad), and check for defective switch or horns.
The fuse is not blown. I checked fuse for power with a test light (light lit up)
Which leads to my question, how does one check to see if power is
getting to the horns. As for horn switches and horns, I will call around for pricing. Any help is appreciated.

This happened to me. But you can also check to make sure your horn is getting voltage by disconnecting the wire going to the horn and attaching a volt meter to it. Watch the meter as you have a friend push the horn button. First check to see that you're getting >12 volts and then check to see that you're getting >10 amps. Checking amps is important since dirty connects or bad grounds can prevent enough amps from getting to horn but a test lamp will still light up! 
A simple test lamp will not allow you to check voltage & amps properly.
