Can you hear the transfer case motor attempt to shift when you command 2wd? Do the indicator lights work properly on the switch?

Expert:  karrs2fix replied 1 year ago.

You may have to utilize a scan tool to test for failure code information and monitor control module data for the best starting point in diagnosis.

Expert:  karrs2fix replied 1 year ago.

Those are common for transfer case shift motor and shift motor relay failures.

I would recommend you utilize a scan tool, testing for failure codes and monitoring the transfer case contact plate switch position along with the*****command from the switch will help . Most common issues on those trucks is the transfer case shift motor, as long as there is no noticeable wiring damage/issues at the motor or connector.

You can always replace the transfer case shift motor as a first step. They are a common failure, accurate diagnosis would be done with a scan tool and volt meter.
