Need some major help with horn troubles, all help greatly appreciated!!!
Ok, I have a 2001 xlt 3.0 v6 it has the factory installed remote locking system, my horn had been sounding sickly for a while, but I hadn't bothered looking into it, untill it finally stopped honking all together.....you can hear the relay clicking when I press on the horn, when I hit the keyless lock button, and when the alarm is triggered, but no beep, just a very muffled "hu hu" sound, I've checked the fuze/ relay box, I've checked the auxiliary relay under the dash. I have also checked the horn itself by connecting it directly to the battery, and all were fine.....however when I tested the leads on the horn connection plug, I was only receiving about 6.5V, can anyone tell me what to check/ where to look from here??? I need to get this fixed asap, again, all help is greatly appreciated! Thanks!

You should have battery voltage (12V) on terminal 1 (the blue wire) when measured to chassis ground with the horn button pushed. Using an Ohm meter you should have .2 ohms between terminal 2 (the black wire) and chassis ground at all times.

Next set your meter to Ohms and connect the red probe to the Black wire at the horn wiring connector and the black probe to the alternator housing or another known good ground point. If the meter reads greater than .2 ohm check G105 located on the right inner finder panel.

Glad I found this thread, seems to be perfect.. I am installing aftermarket horns and need to tap into the signal wire of the stock horns. From the harness above mine is the same, blue wire and a black wire.
If the blue is the 12v and the black is the ground, which one can I use to trigger another relay to make the new horns honk? IE: I just need the signal wire of the horn harness.
Would I be tapping into the blue wire then?
Thanks,
