The horn wire goes down the center of the steering shaft, and comes out of the steering box. Good place to start looking for a frayed wire. That’s proof the horn relay, power in, ground thru the horn ring on the wheel, power out to the horns. You can always pull the “horn” connection at the relay to shut it off. As to why in cold weather, I wouldn’t guess. Finding it while it’s intermittent is a shot in the dark.
