Alright guys, I'm trying to get my horn to work on my 2005 Police Interceptor.

Things I've checked:
12V to the horn, they blow.
Checked ALL the fuses in the under dash fuse box, all good.
Checked the fuse under the hood, its good.

So, what and where should I check?

There's a dark blue wire under the dash to the steering wheel. If you ground it, the horn should blow. You could also look in the trunk to see if there's a small fuse and relay panel there. They usually cut into it to run the siren. There's also a wire under the center of the dash below the ashtray that can be used and if you do have that circuit in the system, the wire color there is white/green.

Bert, is this the small fuse/relay panel your referring to? If so, all the wires are cut that run to it, and it also appears that alot of these go to the strobe lights. Alot of these also match wires where the console was (Also cut). Is thing going to be a problem?

Thank you for all your help. Im going to go look for that blue wire again.

Bert,
Thank you for your help. Apparently the horn draws power from the trunk on a yellow with a green tracer/stripe. That wire was cut in the door jam under the sill plate so the horn wasn't getting power. But now I have power and its on its way to the inspection station.


Thanks everyone.

Bert

That's the one. I forot that it was yellow/green and not white/green. It runs in the console area and loops into the trunk.

Glad to hear that you found it. Good luck on the inspection.
