If the horn relay in the under-dash fusebox isn't "clicking" when the horn pad, switch, clock spring, etc has a problem somewhere along the line.

If you have remote keyless entry, does the horn work in PANIC mode or when locking/unlocking from the fob?

Check wiring at the horn too. Corrosion is super common....

Wiring problems at the horn won't cause the horn relay to not activate unless F37 was taken out. He indicated it is good plus there was very recent work done to the clockspring area.

No horn From “double tap” on remote lock. No horn when pressing “panic” button on remote.

[QUOTE=projectSHO89;20965336]And the relay did what (if anything)?[/QUOTE

I can not hear the relay over the sounds of the power locks on “double tap”.
When I press the panic button all I can hear is the flasher relay working the flashers and the interior chime going off/on off/on….
