Anyone know about wiring issues with a 2018 Ford? Radio and hazards not working…

I just bought a 2018 (1.5L) at an auction. Seemed like a great deal, but I obviously didn’t research enough. The previous owner had a light bar installed on the roof, and whoever did the install messed up the radio and hazards. Now, the radio seems to work but there’s no sound, and it’s stuck on 1060 AM. The hazards won’t work either. I’ve checked all the fuses, and they’re fine. Does anyone know if there’s a wiring diagram or something I can use to troubleshoot this?

It’s probably not a wiring issue. Fords are known for having problems with the ACM (audio control module). When they go bad, they can cause the radio to act up like that. You could try replacing it with a used one, but you’ll need to pull the unit to get the part number because there are different versions of it.

Thanks for the suggestion. Will replacing the ACM also fix the hazard lights issue?

I’ve never seen the ACM issue connected to the hazard lights, but that’s the best I can offer. Good luck!
