I have had my used vehicle listed above LTZ model for two years and never once do the dome lights come on when the door is opened.

I don't see anything on the dash to turn on or suppress the dome lights.

All of the bulbs where a person can press a switch front and back and 3rd row come on with a push of the button in the ceiling.

I am unclear how the domes are controlled and what to check... can it be a simple fuse or something more?

The interior and dome lights are controlled by the BCM (body control module), on some models there is an interior light control switch on the center console so I would check for that. We need to check the BCM1 and BCM5 fuses which are located on the interior left side fuse panel.

Here is a guide to help and the fuse locations as well:

If the fuses are good chances are the BCM is out and needs replacement, you can get a preprogrammed unit by searching Google or Ebay. To be sure you should do a CAN scan which will have a code for failure. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Ken L. Solved - Root Cause, I didn't look up to see the Interior Light Switch, it was set to off. I never even noticed until you mentioned such a switch.
