Not sure if anyone else has had this issue but here's my problem and how I fixed it. I couldn't find anything online about this so hopefully this will help someone else out!
I drive a 2004 z71 Tahoe. I noticed that upon removing the key from the ignition then opening the driver door that the radio would continue playing music and the interior lights would not turn off. I would have to get out, close the door, open the door and then close it again for the anything to turn off. When I would open the driver door the interior lights would not come on. The door ajar warning wouldn't react... etc.
After looking over some wiring schematics I narrowed the root of the issue down to a component of drivers door latch assembly, the mini wedge switch. This door switch is an input to the BCM telling it that hey I'm open or hey I'm closed.
I removed the drivers door latch assembly which has three harness connectors that plug into it. The connector with the dark blue and grey/blk wiring is for the mini wedge switch. I disassembled the latch assembly and quickly realized the root of my issue.
Here is the complete latch assembly
