I just got the engine running after my partial rebuild now I am just repairing loose ends. The problem I am having is the horn is not working. Things that I have tested for:
1. The actual horn it works.
2. Fuse has 12 volts to it.
3. When I bypass the relay the horn goes off.
4. I pulled the airbag horn assembly and it meets continuity when the horn is pressed.
5. When I ground out the the horn/airbag assembly and press the horn the horn sounds,
6. I checked the horn/airbag bracket and I do not have ground.
7. The ignition is grounded but I am not sure if the use the same ground.

I believe the lack of ground is the issue, does anyone know how or where the steering column of at least where the steering wheel mounts to the steering shaft is grounded. Any help would be appreciated.

 

I'm not sure where, but the horn switch is supposed to be grounded to the steering column per the wiring diagrams. The ground wire is the black wire on the green, 7-pin connector under the steering wheel. Don't know much more then that because it's not shown on the grounds diagrams.

 

Thank you for the response darthmouth. My way to resolve this issue was to lower the tilt lever and repeatedly move the steering wheel up and dow to clean whatever contact was dirty or corroded. So far it seems to be working so I will keep an eye on it.
