4x4 problem

[Critcherc]

I have a 99 ranger xlt 4.0 5 speed and my 4x4 lights flash 5 or 6 times randomly, the 4x4 does not work, I know the switch is good and the gem mod is good, I'm thinking the problem could be in the wiring but I'm not 100% sure, has anyone else had this problem?

Find out how many times the light flashes. I think that system has flash codes, so the number of times the lights flashes can help us figure this out.

Welcome to The Ranger Station!

70-80% of the time it's the shift motor, but on the 2001+ I hear of a lot of failures of the 4x4CM, which is a separate part that controls the shift motor (yours has one, it's separate from the GEM). Many times those fail when jump-starting the truck or after the battery has gone dead and been replaced.

If you want the Ford schematic for that, send me a PM (private message - just click on my username and select send private message). Include an e-mail address.
