Hopefully you can track it down and it's an easy fix.

 

What fuses are blowing? With that information, we can dig into the wiring and maybe figure out the cause.

 

The 4x4 fuse keeps blowing when i try to ingadge it

 

The 4WD fuse (#19 - 20A) supplies power to the +12V motor feed inputs to the TCCM (transfer case control module) and then on out to the encoder motor itself. I would test the wiring from the fuse to the TCCM & from the TCCM out to the encoder motor for shorts to ground. Test it while moving the connectors & harnesses around.
