i looked through the wiring diagram and it also shows a fuse #33 (15amp) fuse in the interior fuse box, and in the engine compartment fuse box fuse #11(20amp) fuse.
i believe your problem is probly in the multifunction switch or its wiring.
heres the wiring diagram to help you find the problem
and heres the wiring diagram for the fog lights.
hope this helps you out.
