Hello and thank you for your question.

Can you please tell me what year your Ranger is please?

Customer: replied 12 months ago.
It is a 2008 Ford F250 with 6.4 Super Charge
Expert:  Ron replied 12 months ago.

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.

Customer: replied 12 months ago.
these lights are on the*****switch flashing from*****to 4 low and 4 high.
Expert:  Ron replied 12 months ago.

Yes I understand that but can you scan the system and see if there are any fault codes setting in the 4x4 module?

Customer: replied 12 months ago.
Ok Ron I have 2 codes first one is P183 and P1865
Customer: replied 12 months ago.
I am sorry that first is P1832
Expert:  Ron replied 12 months ago.

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.

Ron we only have 2 wire connector to the transfer case motor.
Customer: replied 12 months ago.
Plus I have no voltage to either wire and I know one should be a grd.
Expert:  Ron replied 12 months ago.

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.

I see that diagram but can not find the relays
Expert:  Ron replied 12 months ago.

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 . See the links below .
