No Horn, No Foglights, No Brights

[seabas2020]

I have a 2006 mustang gt. I don't have a horn, foglights, or brights. I have checked the fuses and swapped relays and that didn't change anything. I have tried both pushing the horn, and using the panic button, and it doesn't respond to either. Any ideas?

I thought it could be the Multi function switch, but when i activate the hi beams, the indicator light on the instrument cluster comes on, so I don't think that is it.

Sounds like wires or fuses. You said you replaced the fuses and relays, but that is what it sounds like.

Check your smart junction box for moisture or melting damage.

I suspect water in the SJB. Look around in/behind it. Check passenger floorboard area too. While you're at it, check the grommets under the hood (search water leak here). I'd bet it is stopped up, and your cabin air filter is probably nasty to boot.
