Exclamation Another Door Lock Issue Thread

Hello fellow ford owners!

I'm working on my 2003 F350 CCLB 7.3 11/02

So for the past 3 years I have been chasing an issue with my driver side door locks. I can lock/unlock all doors with keyfob and door lock switches EXCEPT for drivers door. Driver's door lock has no functionality. I have tested the door lock actuator, replaced the door lock actuator, and tested every single wire in that f***n door. There are no broken or pinched wires in the door loom. I have tested for continuity from the door lock actuator plug all the way to the VSM. The continuity is there but I have zero functionality at the driver's door lock. I've checked fuses, wiggled wires, and even tried yelling at it for a while.

So! Here is my question: Am I overlooking a relay/fuse or did my VSM die on me? Everything else in the truck works as it should and there haven't been any leaks from the windshield into the cab.

Other random information that might help: occasionally on a really hot day when I get in the truck the radio and windows won't work for a few moments and then everything goes back to normal.

Thanks in advance!
