dome light not working, XG300

2 questions:

1) How do you replace the dome light bulbs? There are two in a small
pannel on the ceiling that also has two switches for the sunroof, two on/off
switches for the dome lights, and a selector switch that allows you to
select whether the dome lights are off, on, or on when a door is open. I
was told that the plastic cover just "pops off" but I've pryed about as
hard as I dare and it doesn't seem to be comming apart...I don't want to
break it.

2) What else would I check, as I really don't think its both bulbs. Other
bulbs on the fuse work, so its not the fuse. The selector switch might do
it, broken it the "off" position - I'll check when I get the thing apart.
I've observed that the bulbs use to "fade" out when they shut off and there
was a delay between closing the door and the bulb going out, so either there
is an elaborate circuit somewhere or the computer is controlling this.
Anybody seen this failure before?

Thanks

I've not seen any problems with the fade timer. If the lamps won't
turn on when the switch is in the on position, you've eliminated that
anyway. I've seen a few defective switches (requiring lamp
replacement), but most of the time, the bulbs were burned out.

To access the bulbs, I beleive the lens pries off. Typically, if you
look closely, there's a small indentation where you can insert a small
screwdriver to pop the retaining tabs of the lens loose from the lamp.
