DTC C0321 04: Transfer Case Lock Circuit Open local garage was able to pull this code up but they weren’t able to clear it. Anyone? It will be going to the dealer after Christmas. I’d just like to see if I can check anything

Anyone else have any ideas?

Anyone ? I’m going to check some grounds tomorrow. Confused as why I’m hearing a click when I take it out of 2hi to go into 4wd and then service stabilitrak comes up. But Then goes away when switched back to 2hi

Started getting service 4wd message. Dealer was able to squeeze me in quickly, but were unable to clear a code/do a relearn and didn’t have time to go any further. Mechanic mentioned a communication issue. when I put the truck in neutral and attempt to put the truck in anything other then 2wd I can hear a click then I get a service stabilitrac message. any insight or anything I can try before it goes back to the dealer. I am quite mechanically inclined.

Hello, I just picked up a 2014 Sierra. The truck did not come with a hitch, wondering if the one from my 2004 will fit before I go and buy a new one. Thanks
