sorry for the long post.
ok so i did some forum searching and google searching on my problem to start. so my problem is 4lo locks in fine and locks the front axle. when i hit the button for 4 hi it blinks and just goes back out. i haven't triggered it yet to blink any codes back to me ill do that in these next 3 days. last year i had no 4wd as the front actuator was shorted and kept blowing the fuse. i replaced that with the gm upgrade to ditch the thermo switch for faster axle engagement. so the one relating issue i found was tied to the transfer case sensor/switches. specifically the one that tells it that it successfully shifted into 4hi. so i tried to do some more digging on that rockauto lists 2 switch sensors for the transfer case relating to that. both of them look identical and they both have a 2 pin and 3 pin versions. does anyone have a breakdown of the pushbutton transfer case that clearly indicates where all the electronics are located on the transfer case and what each one does. also if i have the door open when i push 4hi i can hear the motor shifting the tranfer case but it immediately shifts it back. ive googled for a transfer case breakdown a few times and found some good ones but they aren't tied to the other half of the image that tells me what it is.
