The interior backlighting isn't working. The headlight switch, cruise control switches on the steering wheel, gear select at the center console, and row of switches below the heater controls all are not illuminating. I checked fuse #10 in the inside fuse panel and it was blown, replaced it with no change and the fuse is still good.

The smart junction box (fuse box) in your vehicle has fet transistors that can blow or will not allow voltage on a particular circuit if the module detected a circuit issue. Sometimes you can reset the module by disconnecting the connectors for 3 minutes or so and reconnecting. But if the fet transistor is blown, replacement is necessary and finding the short circuit should be done before replacement. I've attached a wire diagram so you can see how the illumination circuit is powered through the module from the violet-gray wire.
