I feel I'm chasing my tail and might have to simply live with no 'automatic' interior and trunk lights. Once again, I can't believe I'm the only one who has this problem.

The Central Locking unit was inside four Happy face bags with two plastic ties around the tubes. It looks new to me.

I have not a clue as to how to remove the cover. Oh, I could get it off, but not without bending and prying.

And best I can figure out it has nothing to do with the dome lights.

In front of me are three separate wiring diagrams which include the dome lights. They all indicate the dome lamp control is in the Body Control Module.

After that I'm totally lost unless there is a diagram which indicates what each of the 16 (or so) modules are for.

I assume that hot swapping is not a good idea.

If anyone out there has found the correct module for the dome light, please let me know. There is a small, single, white one which I suspect 'might' be for the dome light control.
