Weird issue..need help/guidance...

Have a 2017 cc fx4 Lariat f250 with 44500 miles. While driving or even sitting idle the air bag light will come on and my AC system will shut off completely and be unresponsive. Even my electric windows will stop working. Once air bag light cuts off then things return to normal. Does this on and off quite a bit at times and at other times will do fine and not have any issues at all. Would like to have this fixed or do myself however i do not know where to begin. Any help would be greatly appreciated.

Thank you!! I checked the two connectors attached to the rear frame and sure enough, there was black residue and corrosion all inside of it. I was able to clean as much as possible and add dielectric grease to the connector and reassemble. All others looked ok. Hoping this helps. Thank again for the help.

Please report your results.
If this does not work there was another thread some time ago reporting similar symptoms that ended up being a defective connector in the dash
