My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
My info is limited on your model here but I see no one else has responded and thought I would see if I can help here.
If the interior lights are not working with any of the doors opened or light switch on at all and all fuses are o.k. I suspect a control unit failure like a lamp control module at fault needing replaced or a sam control unit.
The fault codes will need checked in all computers using a scan tool that will plug in and communicate with all computers.Once this is done any codes set will need diagnosed to locate and repair the fault here.
Thanks Pete
