99 ranger 4x4 not working, flashing 4x4 lights

[dean-93]

just bought a 1999 4.0 5 speed ranger 4x4 ,and the 4wd will only work after i reset the battery/computer after i reset it i can go to 4hi to 4lo to 4h again but when i try to go back to 2wd it only works like half the time and if it dosent work the hi and lo lights flash and then i half to reset the battery again to get it out .

my abs light is also on if that could be related,and the interior binging noise goes off while driving sometimes.

i would think the wiring is fine since it does work sometimes but i dont want to waste 100$ buying a shift motor and that not being the problem.


thanks for your help

also forgot to mention i went thru all the fuses.

i also found a relay box under the dash near the gas pedal do these have anything to do with 4wd.

It's likely either your shift motor on the transfer case or the 4x4CM (control module).
The relay box you found is for battery saver, but it does feed the GEM and 4x4CM.
Not likely to be your problem with flashing lights though.

Your 4x4CM should be behind the radio bezel with the GEM, IIRC.
