4 wheel drive not engaging!

[kzman28]

Is there anyway of running a hot wire to the shift motor, to engage manually? I have changed everything possible to change, still not working.

Try and explain everything that you have done to try and fix this problem on your own and explain any noises or anything thats going on so that we can get a better idea of what maybe going on with your truck. Your sure its not the t-case itself? Have you tried to put it in 4low?

As in my old post.I have changed both front and rear hall sensors,speed sensor,gem,all relays,shift motor,new t-case fluid,4wd switch.Also had it in 2 shops and they can not figure it out either.One shop told me it was the gem!!!I tried 2 of them thinking the first one was bad but no luck.
