Hello and thank you for your question.Can you please tell me what year your Ranger is please?
The light flashing means the system is setting and storing a fault code and or codes. If you can scan the system and post back with the fault codes I can advise you from there.
Yes I understand that but can you scan the system and see if there are any fault codes setting in the 4x4 module?
A code P1865 normally indicates a problem with the contact plate power circuit. This is the Yellow (YE) wire at pin 2 of the 6 pin transfer case shift motor connector C350A. This wire will normally have a pulsing voltage of about 0-9 V when cycling the key on. Thats the code I would deal with first. See the steps in the link below.

Take a look at the wiring diagram in the link below, power to the transfer cases motor comes from the relay in the Aux relay box.https://dl.dropboxusercontent.com/u/104923897/Transcase%20Mar%2031.pdf
Okay , I rechecked it and thats the gas engine system, and the wrong diagram. For your 6.4 they are located in the under hood panel .
