The transfer case control module is under the left side of the dash, by the steering column. If it is a non auto selectable FWD, you can ground pin 13 at the diagnostic connector(it is an orange wire), and the switch LED's should flash codes(If any) It would only be 1-4. It sounds like you may have a module faulty. Does the vehicle have any aftermarket stuff installed?
