My only suggestion is to change the 30 amp fuses, in case on has failed but you cannot tell visually. Also inspect the power wires to make sure there are no additional fuses or circuit breakers. Let us know if you find a solution.
I checked the fuses with a volt meter and they were good. The Schematic only shows 1 fuse between the battery and the (vcm) Accessory fuse box.
