I'm not sure, but I don't think the interior lights go to a common ground connection like that.
Their circuit is hot at all times, and goes on when one of the devices on that circuit (e.g. a pin switch in the door, or a map-light switch) opens a path to ground. So I reserve the right to be wrong (like _that_ never happens
) but I don't think the interior-light circuit would be affected by that particular corroded connection. (Great web page explaining that problem, BTW...)
