I was wondering the same for a 2001. I have a map light on either side of the rear view mirror each with their own switch. They do not work but I assume they will come on with the headlight switch.
Should there be any floor illumination as well?[/QUOT
Not sure about your '01, but the mirror lights should work independent of the headlights. Those bulbs do burn out. I want to say there was illumination in each side well under the dash(??).
