No turn signals or heater controls... Trailer to blame...

[SAR_Runner]

I was having issues with my trailer lights while using the factory trailer plug. I do have a brake controller and it seems to have died as well. I don't have turn signals or heater controls. There aren't any blown fuses in the main or sub panel... anyone else have this happen? Was going to pull the positive lead and let it sit for a while. Also going to pull off the factory trailer plug and see if it fixes it.
It is an 03 v8.

Similar thing happened on my 99 a faulty rental trailer wiring burned out a component behind the dash and killed my fuel guage, smoke came out of the dash. No fuses blown. I was able to solder a new one on and fix it.
