Can anyone tell me where the horn is?  Mine is not working and I need to see if a wire is disconnected.

Try your fusebox first.

Check Horn Fuses (F20 and F24) and Horn Relay (R2) in the fuse box under the hood. C131 is the 2 pin connector for the horn located on the passenger side front.  You'll need to remove the front lower cover (looks like 6 push pins and 7 screws).  Check horn by applying 12 V to horn directly.

 

If above okay, spend less than $30 for an OBDII ELM327 module and the ForScan App and scan modules for DTCs.  There are many for the Horn which should help isolate the issue from the horn switch, clockspring, BCM, relay, and to the horn itself.

Thanks, I checked the relay and F20 but not F24, I found where the horn was located in the wiring diagram and figured I would have to remove the bottom cover. I do have an ELM327 and ForScan and when I checked  for other issues last week there were no indications of issues, but probably need to test again.

Update: I found where the horn is.  It's on he Right side and is accessible by removing the long plastic cover underneath on the front of the car.  I had a loose connector and the horn was working intermittently.  It is fixed now.    I had to remove the same plastic cover when I added foglights to my SE
