Hello bradfordtrot.

If the light is flashing it isn't able to complete the operation of the shift.
Usually the problem is the actuator on the transfer case. This devise consists of an electric motor with internal sensors that tell the module the position that the shift shaft is in on the transfer case.
There are other possible issues that can cause this as well but less common.
Not sure how much mechanical ability you have so not sure how to advise what your next step should be. If you have experience, tools and a wiring diagram (added below) for the system it can be done.
If not,I would suggest that you have the system checked by an experienced mechanic.
Thank you for using FixYa.
