Horn does not work

[Fordication]

Checked the horns in the grill, work fine. Checked the power to horn on steering wheel, no power. Where do I look now.

Is the horn relay in the fuse box?
On the top of the fuse box. horn relay and key in buzzer.

The wire in the column is a ground switch , it only provides a ground to close the horn relay so you probably have a problem withe the relay

If the relay is in and it's working. check the bulkhead connector 24 for power when pushing the horn button.
