The rear trunk lamp is also shared by the antenna motor - it was one fuse in the fuse box that blew and caused the trunk light not to function.

Check for voltage at the connector.

your car does not employ a body control module for the rear or front dome lamp, infact the only module it has is a convenience module which works to self close the windows when the doors are locked with the key.
