Hey Mustang Forums...first time threader, long time reader

So I was bit by the infamous water issue on the passenger side due to a clogged drain by the cabin air filter. It has caused some sort of fault that results in the button illumination for the steering wheel and console (Driver Control and Climate Control Pushbuttons) to stay illuminated. I have taken everything apart and everything has dried out, but I continue to have this problem over a year later. It ultimately drains the battery.

Any troubleshooting help would be great!
