02 Silverado

Hello all. Charles here I'm a new member. And am having issue with my truck.

I got myself stuck, in snow. Winched it out the next day. But list 4 wheel drive. Dash switch acted funny, so changed it according to alot of posts. No good. Cleaned ground. No good. Changed shift motor. All seemed great. But no 4 wheel drive still. Service 4wd light gone tho. Switch lights only work with headlights on now. I'm at a loss. Co387, co374 and b2725 are the codes I had retrieved. Any idea what else is wrong??? Please help

All fixed finally after changing everything including the transfer. Cooked the clutches in it. The encoder motor was also bad and that threw me off when after that it still wouldn't work. Scan scan scan scan. Get it scanned when the screw up. Saves alot of time and money
