Hello, I have a 2004 Falcon BA XT. The Horn would randomly turn on (single long blast), even if the car is stationary. Also, the Hi Beam would turn on by itself, only if the Low Beam was on, otherwise its fine. The remote has no battery inserted.
Does anyone know if this is a BCM issue, or a wiring problem? Thanks in advance. |

I'm going to take a guess at this point, at a wiring fault somewhere. ill check some diagrams over the weekend and get back to you. but from memory headlights and horn aren't through the BCM.

Thanks all for replying. I took the Car to two separate Mechanics.
Mechanic1, was a dedicated Ford Service who quoted a Light Switch connection, and the connection inside the steering wheel for the Horn. Mechanic2 quoted the BCM, and also had the wiring checked by a sparky, and given the all clear. |

I removed the Hi Beam Fuse, and after a while the Low Beam lights would come on by themselves. Nothing else electrical is affected. Cheers guys! |

A big thanks to those who have replied.
I had the Clock Spring replaced for the Horn, and a Light Switch installed for the Headlight issues. Its been a few weeks now with no further problems.
