Having the same problem except mine won’t engage into anything other then 4H. Had a bad wiring harness that needed replacing. However, even after replacing the harness I am still experiencing this issue. Any ideas?? How did all of you solve this problem??
I am having a similar issue with my 06 after replacing both front CV axles and oil seals. 4wd light and center diff light are flashing as soon as you start the vehicle.
