I'm glad to find this thread, since I've been baffled by the dome light as well. It never worked for me consistently. I tried different methods and found that the switch with the word "off" (as shown in Timthom's pic.. the button on the right) seems to control the dome light to go on/off when the doors are opened. I'll have to see if it consistently work this way.
