The trunk open button is run through the driver and passenger side multiplex control unit. These control units are fused in location #44 and #56 in the under hood junction box.
Here is the wiring diagram that shows it.
The dome light runs through the passenger side multiplex control unit and the interior lighting control module which is fused at #31 and #57 in the under hood junction box.
If you are having a problem with both of these items I would suspect the passenger side multiplex unit after checking to make sure the fuses look ok.
