2006 hyundai tuscon windows, locks, brake lights not working

Vehicle was submerged up to the fusebox in driver's side.  Drained it and the
vehicle is running good after a new starter installation.  The brake lights, door
locks, and now, a week later, add the air conditioner to the list of things, that do
not work.  Checked the fuses on driver's side and all tested good.  What else
could it be?  Your thoughts, please.
