Interior lights not working...

[thunder2]

Exterior lights all fine. Dash fine. Glove compartment fine. Top two middle lights by the sunroof, housing there but bulbs missing. Lights by the footwell, don't come on.

I think various people have looked at this but no one seems to be able to come up with a fix. Can anyone give a starting point for when I take it to an auto electrics person?

Any help, much appreciated.

As Stefen suggested, the center switch is important. Three positions: always on, automatic on (door activation), and always off. That should control the "dome" light, the door footwell lights and the C-pillar lights. If they don't all work together, then look at individual bulbs.
I once lost a map light from someone pressing on the lens - it pushed the metal pole out of contact with the power strip inside the housing. Easily repaired once I figured it out.
