ok guy's here the deal. last night it was setting in the drive way and went nut's about 12:30 the horn went off and the light came on. IT'S NOT THE ALARM....
the horn is constant not a beep beep and the light don't pop up when it's doing this so disconected the battery.
i try to put it back on and it will be cool far anyway from a min to 5 min. but it will start to go off sooner or later. so i'm gussing theres a short in it but if any of you have any hint's or think other wise plz help

It sounds like two problems.
The alarm is getting a false signal.
The alarm is not switching the horn & lights on/off.

I would start by pulling the plug on the theft deterrent module in the CPU (by the driver's left foot).

In the S5 on-line manuals, it's in "15- body electrical"
The link is in my sig below.

I'm in Flemming Island.
Where in Orange Park are you?

ok now can some one tell me what the BTN fuse is all about i can pull it and it stop and the light will work right but no blinker and radio

BTN = Brakes, Taillights & turn signals, iNterior lights.

And you never answered what light???
In your first post in this thread you said a light... what light???

the head lights

So, the headlights and Horn are going off by themselves at 12:30 am???

Is there an aftermarket alarm or other electrical system installed, as the factory alarm would not control the headlights, even if it did fail.
