could my front diferential actuator be possible bad? shorting out or something? cause today i god stuck and it i take the ATC fuse out and left the key in the on position i could hear the front diff motor working but then is got stuck into 2wd and i couldnt get it to go into 4wd at all , im seriously stumped , its gotta be either the tccm or the actuator to the front diff, any idea?

 

* UPDATE ,
the new transfer encoder i installed was no good,,,, installed another new one now , auto 4wd , 2wd, 4hi/lo all work!
had to replace switch and also actuator on TC
had codes
c0308
c0327
were coming up

PM if you need help with your 4wd i learned alot in 8 month about auto trac TC
