Door lock issue resolved.
What I found when I was testing for voltages and continuity at the BCM connections was an apparent bad connection of one of the BCM connectors. I removed these to do my testing and after I reattached them the door locks would then lock as they should from the switch and from the fobs.
I appreciate everyone's help here. Thanks to all who provided input here.

Not really sure what the root cause is or was. I am assuming just a bad connection at the contacting pin to connector. I had those connectors pulled off the BCM to do the test that you sent me a link to. All that checked good then I assumed it was the BCM going bad or at least the lock relay within the BCM. I put the connectors back onto the BCM and just for the heck of it I tried the door locks and they worked. After that while locking and unlocking I did jiggle the harnesses around and could not reproduce the issue. So hopefully it will last. If not then I will need to revisit the wiring and connectors for a better inspection.
