2008 Mustang Horn


#1

So out of no where, my horn went out on my car. I checked my relay with a fuse tester and it tested fine. My horn works when I press my alarm button but it wont work when I hit the horn button. Any ideas on what can cause this and what needs to be replaced?

I think you’ve already eliminated about 90% of the troubleshooting here. I’ll give you a hint…the horn button makes the horn blow. Barring any broken wires…you should be able to fix the problem rather quickly.


#3

I would think you either have a bad horn switch or a bad clockspring in the steering column. Do you have any other buttons on your steering wheel, like for the radio or cruise control? Do they work?


#4

Another thought . . .

Some cars have separate horns for the horn and alarm function


#5

Is it safe for me to attempt to fix the problem myself? And yes, all other functions work on the steering wheel.


#6

It depends on your level of expertise when it comes to mechanical work. If you have never worked on a horn switch or clockspring…I would advise you to find a good independent mechanic. Make sure the battery is disconnected if you do attempt the repair. Also…make sure you have a good repair manual available and read it over before you start.

If there is an airbag in that area, me, I’d take it to a shop.
