CONDITION:
The horn may intermittently sound without switch input or the horn may be inoperative.
CAUSE:
The cause of the horn intermittently sounding without switch input may be moisture intrusion into the horn connector body, causing a resistive short
circuit between the horn connector terminals.

causing the 10 amp HORN fuse to open.
