Hi SANDY,
It sounds like it is one of the door latches. With all of the doors closed and the dome light off, door to each door and without opening the door wiggle the each of doors around to see if you can get the light to come on.
Here is the wiring diagram for the system. There is a dome light relay that could be bad.
Please let us know what you find
Best. Ken
