Transfer case control module (electric-shift models) — replacement
The transfer case control module is located under the instrument panel, to the right of the steering column.

If a problem arises with the transfer case control module, it is recommended that the job be left to a dealership service department or other qualified repair shop. A new module must be programmed with a factory scan tool by a dealership service department or other shop equipped with the proper tool and software, so even if you were to replace the old module with a new unit, it wouldn’t work until the vehicle was towed to a dealer (or other properly equipped repair facility) for programming
