I've never know 'till now about the fusing for the interior lights on our G's. Apparantly there isn't a fuse, but a resettable breaker that is reset by disconnecting the battery.
Who knows where the breaker is, but at least we can get the interior lights back on.
These lights include the reading lights and the step lights in the doors. Not sure about the side lights in back of the Sedans, but I suspect they're on the same circuit too.
Here's a link to F/A explaining all about it:
