Riddle me this.. switch in the "automatic mode" for the dome lights.. lights stay on. They never time out.. as in normally when door is left open after a while they still time out - or when car is started. Put the roadsters (problem car) BCM in my coupe.. works fine. So are we off to check the Security pump module time? If a door switch is bad .. would it prevent the module from eventually timing out?
Lighted door sills await your resolution..
