Well if you replaced the module on the case itself, I would pop the connector off the module on the tcase and on the front diff. have a buddy hit the switch while you test the connectors to make sure power is getting to the connectors. If not, you need to replace your switch. If you do get power I would replace the front diff actuator. Dont quote me on that because your problem could be bad wiring, however thats not very likely.
