This fuse should be labeled ATC in the underhood electrical center. This has been a common problem with these. Normally this is caused by a faulty transfer case encoder motor. You may want to try replacing the fuse and unplugging the motor to see if you get the fuse to blow once again. If it does, this would be likely caused by a faulty transfer case control module, or a wiring issue from fuse to the transfer case control module, or a wiring issue from the transfer case control module to the transfer case control motor. Here is a schematic of the wiring for this system. Feel free to contact me with any questions! Good luck!
