Horn doesn't work (but CC does)...
Just bought a 2005 Excursion, and the horn does not work. I've scoured the forum here, and while this is oft-reported, it is usually accompanied by the cruise control also not working. For me, the cruise control works fine, just no horn. The horn also does not "chirp" when I hit lock on the fob twice (it should).
Suspect a bad connection to the horn, or a burnt out horn, but I'm not sure how to diagnose it...

Test that you get power to the horns.
Pull the plug from the horns, hook up your volt meter, and had someone lay on the horn. If you get 12+ volts, the horns are dead. If not, you've got a break in the circuit somewhere.

Still trying to find access to the damn horns, without pulling the battery... They're supposedly under the "fender apron". Do I access that through the wheel well (i.e. behind and above the wheel), and if so how? I don't see any bolts in there that I can remove, just some rubber cladding, and not sure how I would pull it... Or do I access it from the engine compartment somehow?
I can hear a kinda clunking noise from the general area where the horn should be when I (have my son) hit the horn, or when I double-tap the lock button on the fob, which sounds to me like power is getting to the horn, but the horn is just burnt out. Unless there's some relay associated with the horn, and that's what I'm hearing...
