The horn itself could be disconnected. Check under your hood to make sure the connection is still good. Good Luck. I hope this is a 4.6!How can I fix my horn on my 2004 mustang gt?
COUPLE THING YOU WOULD WANT TO CHECK FIRST THE HORN ITSELF MAKE SURE IT WORK AND HAS POWER AND GOOD GROUND GO THE HORN IF OK THEN CHECK THE HORN SWITCH ITSELF. LAST OF ALL CHECK THE SYSTEM WIRING FOR OPENHow can I fix my horn on my 2004 mustang gt?
if the fuse is good, you may have a connection problem. most cars (fords especially) develop connection problems with the button on the steering wheel. it doesnt make a good connection on the back side of the wheel.
a quick way to tell if the horn is good is take it off, get you about 2 feet of a spare piece of wire and cut it in two. put one end on one connector of the horn and the other wire on the other one. brush the wires against the + and - posts on the battery. the horn should go off. this means of course the horn is good. now you can try to dismantle the steering wheel and check the wiring behind that, but you have to be careful so as not to set off the air bag. sometimes either the metal gets corroded or a screw comes loose. just have to look at it. hope this helpsHow can I fix my horn on my 2004 mustang gt?
The horn itself... Been having issues with them lately... check for power and ground to horn with button pressed....
If you have keyless entry, hit the panic button, it bypasses the horn button, if horn works now, you have button issues, if still no you probably have Horn itself issuesHow can I fix my horn on my 2004 mustang gt?
crazy good ideas. I would head for the wires first, but one thought I have is that most cars have a high and low pitch horn so if it were the wires, odds are one horn would work, but not the other, unless someone unplugged them on purpose. If your horn is used by your alarm, that might be a reason to do that. One other thought is that in older cars, the wires in the sterring wheel frequently chafe or break. your car is newer so this seems unlikely. I just remember a car that used to honk the horn every time you turned left. :-D It was a GM though so that explains it.
