4WD Fuse 24 keeps blowing?

Vin #: 2GCEK19R0W1211770

I am looking for an electrical schematic.

I have a 243c transfer case, automatic.

I have installed brand new transfer case, transfer case switch, front 4x4 actuator, and encoder motor.

When I disconnect these new parts, the fuse still blows.

Vehicle will go into 2HI but not 4HI or 4LO.

DTC Codes are #1 and #2

What else does circuit 241 operate?

Do you have access to an electrical schematic for my particular VIN# regarding this issue?

Any help would be appreciated.
