Inspect and make sure the dome lights are turning on when the door is opened.If they are not working as well when the door is opened this can indicate a fault with the drivers door latch itself in some cases as I have seen and had to replace before.I would have the door latch open/close signals checked with a scan tool to see if the latch itself needs replaced.If the dome lights are coming on with the door opened let me know so we can continue.
