Update on the door control problem. Did some research and testing and figured out there is a broken wire in the harness where the door hinges. With the door closed everything works but when it’s open it doesn’t work. Wiggle test confirms that I can make it work with the door open. So if the door is open with the truck running it loses connection with the BCM and sets the code. Now I have to get it apart and fixed.

Not hard to access. The rubber boot disconnects at the jam area from a plastic collar. Pull off and pull back. If you need the boot off, you can pull it from either side or access where the harness goes thru the hole to under the dash and unplug the harnesses and feed back thru the hole and then pull the boot off for complete access.
