My 2005 G35’s horn randomly started going off in the middle of the night after several hours of being off. It was NOT the alarm, but just the horn going off like someone was pressing it randomly. It was rainy so I believe there is a short somewhere. I disconnected the battery and will will remove the horn fuse in the morning, but I need it fixed as soon as possible to honk at idiots. Any suggestions?

 

Have u checked the IPDM. Its known to flood during a rain, causing all kinda electrical issues.

 

Could a clockspring going bad lead to the horn honking randomly?
