    I will try to keep this as brief as possible.

    My issue: Interior lights stay on with all doors closed until the BCM times out. (10 or more minutes?)
    I am lead to believe it's a bad door actuator not telling the BCM the door is closed. So, which one...? Using this wiring diagram:



    and doing this:



    I have determined that the 3 passenger doors all function as they should using "DK BLU" (bottom pin in this ^^^ picture). I have an open circuit when the door is shut, and I have continuity to ground when the door is open.
    There are two other dark blue wires in this connector. One solid blue, one blue with white.
    When I check the other dark blue wire, I have continuity all the time. (DS door open or DS door shut). Not shown in picture. Bottom row, 5th from left. Thinking this may be my DS door wire?
    When I check the dark blue with white, I have no continuity. (DS door open or DS door shut). Top pin in picture. This one may go to the headlamp switch according to the diagram.
    I am thinking my manual has the wire color combinations wrong or it's outdated for my car.

    So, I guess what I'm asking is; Am I using the correct spot to check continuity for the drivers door actuator? Also, wouldn't the DIC show the door open if the actuator wasn't opening the circuit?
