Potential Alarm Problem

[Ravenkeeper]

Truck was parked in the sun, on Edwards AFB, by one of the chapels, while my son and I were doing some modifications to their A/V setup. 108°F.

 

I've noticed that the horn will sound, like someone tried to break into it on random hot days, at home. Didn't hear it today.

 

Anyone else have similar issue?

I had this issue on a previous car, but haven't read anything about it relating to the trucks. Mine was just faulty wiring
