Heard a noise when turning the corner then the horn and the cluster went dead

Hello, where did the noise come from? What kind of noise was it? For the horn to go dead, I think about the sliding contact behind the steering wheel that can influence the horn switch operation. For the instrument cluster, I think of some kind of loss of power in the circuit, like a common fuse.. Too hard to know without putting all the pieces together in person to diagnose your concern.

Unless you were actually pushing on the horn and observing the cluster at same time - exactly how was that conclusion derived? Is it possible these two concerns happened at different intervals?
