Rear power outlet in 99 GC

I blew the fuses for both the front and rear 12v outlets in my 99 GC. I found and replaced the fuse for the front outlet, but I can't find a blown fuse to go with the rear outlet.

Is this fuse in the block under the dash, the PD module under the hood, or someplace else? It's starting to drive me crazy!

Thanks,
steve
