If water got into the fuse box, I'm pretty sure I'd be having much more electrical problems than just fog lights don't you think?
All of the other lights have been working fine (low beams, high beams, turn signals, hazards, DRLs, parking, brakes, 3rd brake, tails, reverse, license plates).
Is the relay/driver side junction box assembly out of the question at this point?

Before you attack the relay/driver side junction box assembly, which is the assembly that contains the interior fuse box, trace the continuity of the pins/wires from each fog light wiring harness socket (your pic 3).
Measure the resistance from (left fog) A18 pin 1 to GND, measure resistance from (right fog) A29 pin 1 to GND. Measure the resistance from A18 pin 1 to A29 pin 1. Each measurement should be less than 0.5 ohms.
Find the location of Junction Connector A40 (see pdfs below), and check it. Note whether this was properly connected (after the engine work) and seated. Hopefully this is the source of your problem. If all looks good disconnect it to make some measurements. Refer to the wiring diagram.
Measure the resistance from A18 pin 2 to Junction Connector A40 pin2. Measure the resistance from A29 pin 2 to A40 pin 1.
Measure A18 pin 2 to A29 pin 2. Each measurement also should be less than 0.5 ohms.
Do the wiggle test while checking continuity. Hopefully you will find a loose connector or intermittent wire.
See the enclosed pdf for the location of Junction Connector A40, A18, A29.
If you haven't found the problem by now you should check continuity between A40 pin 5 to the relay/driver side junction box assembly at connector 2D pin 9.
This will be more involved in order to access that connector.
