If the small lamp in the switch comes on, that tells you the relays for the lamps were indeed turned on in the engine compartment fuse box. Probability is that the ground pack on the right forward frame rail adjacent to the hood riser is suspect. FYI, the fan grounds go through it too. Have you checked the fuses yet?

?? I think you mean in the underhood electrical center, right? Minifuse 6 in the underhood electrical center provides 12 volts to the fog lights themselves (provided the relay is functioning), and the indicator lamp on the switch(which the OP says is illuminated when the button is depressed).

Fuse#6 in footwell also runs dash and rear lights.

So again, based on the OP's description of the indicator light being on, the the fog lights not illuminating, it suggests the following:
1) Minifuse #6 in the IPEC is good
2) Minifuse #6 in the UEC is good
3) Minifuse #32 in the IPEC is good
3) The BCM is receiving a fog lamp request via the switch
4) The BCM is providing a ground for the fog lamp relay
So that leaves:
1) The fog lamps themselves
2) Wiring from the load side of Minifuse #6 in the UEC to the fog lamps
3) Ground G102 or SP100
