Horn not working?

[Hav One]

Hey all,

I appreciate the help given on the previous post I listed. I now have an issue of my horn won't work when trying to use the steering wheel, but if i set the alarm of it works fine? Has anybody seen this before?

Thanks!

The BCM controls the horn relay ,the steering pad switch is intergraded part of the air bag circuit ,the problem may be there .You need a scan tool can check if there is a input from the horn pad.
