Hi my name is ***** ***** I will be happy to help with this today.

From what you have described here this sounds like an internal electrical fault in the FCM itself.This is the Front Control Module.The horn pad sends the horn signal to the FCM and the brake light switch sends its signal to the FCM to turn on the horns and the brake lights when needed.Since the horns will stop intermittently when the brake is applied this sounds like the FCM has an internal electrical fault in it needing replaced.The FCM can be a common component to fail and cause electrical issues like this here.

The only other cause I see that may cause this here is if there is shorted wiring leading from the steering column to the FCM itself.The wiring needs checked over and if found to be o.k. I suspect the FCM needs replaced.
