2014 Subaru XV Crosstrek electrical system problems

Tl* the contact owns a 2014 subaru xv crosstrek. While driving the vehicle, the heating system became inoperable. The vehicle was taken to an independent mechanic to be diagnosed. The contact stated that the electrical wires in the air conditioning/heating system control unit were melted. The contact was informed that the air conditioning/heating unit needed to be replaced. The vehicle was not repaired. A local dealer and manufacturer were not contacted. The approximate failure mileage was 80,001.

Horn does not work. Many times I've had to swerve out of the way of traffic about to hit me because my horn doesn't work. A few times I have almost run into others trying to avoid a collision that would arguably be much worse than letting someone hit me. I've done some research and what others have found is that it's the clock spring or wiring that needs to be replaced/repaired. I'm assuming the horn stopped working when I turned my wheel.
