fuse box fried

I have a 06 3500 4x4 Big Horn. It has the 5.9 and a Automatic. The truck is stock with 50K miles . When I opened the door today, my blower motor was running in the second to highest position with the key off. I smelled the electrical fire smell and checked under the hood and found the fuse box next to the battery on the driver side really hot. Immediately disconnected both batteries ( which would have erased any codes?) and pulled the fuse box apart. No fuses were blown. The hot spot was up in the corner where the 30 amp fuse for the diesel pcm is located. Melted the circuit board. Has anyone else seen this? If the ignition switch is bad and staying on, why would it have not just drained the batteries? New fuse box is over $700 so I don't want to fry another. Truck still looks good sitting in the drive though. This is my first post but I've seen a lot of helpful reply's on other subjects. Appreciate any help to get this rig running again. Phil
