4WD WILL NOT disengage!! Mud nowhere to be found.

Asked by Aug 25, 2014 at 07:47 PM about the 2005 Dodge Durango SLT 4WD

Question type: Maintenance & Repair

Is there a way to manually disengage 4WD? I've tried everything I can think of to get it
to disengage - patiently driving backwards & forwards at low speed, switching in drive
and in neutral, tapping the brake pedal (lol), taking key out for a few minutes and trying
it all over again...and again. I even got my ex to crawl under and try tapping the TC shift
motor while I switched and shifted (and he lives, no worries) I don't want to detach the
wiring to the shift motor while it's still stuck in 4wd and I'm concerned about what
turning on dry pavement is doing to my "baby". There HAS to be a way to get it to
disengage...anyone?

Tried disconnecting the battery and removed and replaced the fuse as well and checked the wiring to the shift motor (although not thoroughly - just a quick lookover) Thinking of jumping the shift motor to see if the problem is before or after - it's pretty much electrical before, mechanical after, true?

Yes it will be the actuator on the transfer case.

There's no power between the fuse block and the shift motor...The TCM works when jumped, no fuses are blown and there's power to all, the relay works, there is power to the switch, tried a different FCM (not reprogrammed, and didn't do a thing), no codes come up on diagnostics, I've lifted one tire, two tires, (trying four tires after lunch)... anyone have a schematic for the wiring harness between junction block and FCM? Running out of ideas here...

So, guess I should've posted the outcome. After weeks of choosing gravel over pavement, and pulling off to spin a bit in gravel to eliminate any binding, I can thank the Barrie roadworks department for fixing the truck I hit a series of potholes and thought I heard the transfer case motor....sure enough the 4wd light was off! I pulled off onto a curb, unplugged it (covered in plastic and tied up later), and just let it stay that way with no more problems. I still don't know if it was electrical or a matter of debris, but I'll save that for a time when I'm either desperate or feeling adventurous.
