I suppose power steering is not working and have a red wheel on dash.
Most probably water still got inside, you checked connectors but not inside ECU or boots.
You should remove them and take a look. Keep in mind even if you dry out everything it still won't work because ECU is locked....
Professional power steering workshop should manage to fix this, but I'm not sure you will find one close to you. So go for another rack.
 
External plugs open to the air have seeks in place to hold back water, but I'd check all connectors related to see if something's become wet.
