I've got a (new to me) 2005 Z71 AV that I bought over the weekend. I noticed that when I turn the key to the 'Run' position, the windshield wipers come on (if they're engaged) and the instrument panel backlight comes on, but no other lights come on at all. Everything works as it should when running. There is no CEL and the only warning displayed is "service airbag".
My main issue is that when I try to engage the 4WD, the transfer case buttons don't illuminate and I don't hear anything moving or engaging and I just want to know where I should start with troubleshooting the 4WD
