I totally respect your experience Bill.
But here's the details.
1.) Problem is intermittent and completely random. Lights work as they should for weeks, then one day, will just decide to stay on!
2.) Switch/actuator tested fine while out of the car.
3.) At some point the other plug (controls door lock/unlock) had been tapped into. Whatever they installed has been removed, but the little inline wiretaps were left behind. <--- This is why I suspect the BCM. I have no history, but I wonder if whatever was installed, cooked something inside there.
