63 Horn Problem
In getting the car ready for the road I found that the horn wasn't working. I put in a new relay but that wasn't it. Now I think it is the contact under the horn button. How do you remove the horn button to replace the contact?

Re: 63 Horn Problem
It simply 'pops' off by up toward you. But, you shouldn't have to 'guess' as to why your horn(s) don't work... Why, not put 'science' to work?
The top of the Delco Remy horn relay cover is embossed 'H' and 'S' on both sides so it doesn't matter which way the cover was set on the relay before it was crimped down.
The emboss marks tell you the function of the relay's connecting terminals on the bottom side of the case directly beneath the cover's emboss. 'H' means that post is power out to the Horns. 'S' means that post runs to the Switch in the steering column (contact closure to ground).
You can unplug the horn relay from the engine harness and manually exercise it. Take a jumper wire from the 'S' terminal and touch it to ground. The 'H' terminal ought to jump up to B+ voltage levels in response. Now, you've verified the horn relay is working like it should.
If you can force B+ out of the horn relay and the horns still don't honk, go to the front of the car and verify B+ is actually getting to the horns (defective wiring harness?) AND that the horns actually have good ground paths where they're bolted on...
If that checks out, it's time to remove the horn(s) and bench test them. It might be that they simply reached the limits of their useful economic lives... -
Re: 63 Horn Problem
PS, want to test the integrity of you steering column horn switch? Connect an ohmmeter to the horn relay plug that was attached to the 'S' terminal of the relay and connect the opposite wire of your multimeter to ground. Go push the horn button on the steering wheel and the meter should change state from high/infinite ohms to low/no ohms...Comment

Re: 63 Horn Problem
Jack, You did a nice job explaining how to check the horn operation.
It's probably the wire inside the steering column. Not a fun thing to fix. JDComment
