2000 Escalade Map lights don't work

[73impala]

Hey my friend has a 2000 escalade and when the doors open all the interior lights come on but the map lights. When I push the over ride button on the headlight switch all the lights go on and off and the map ones just remain off. But when I push the map lights to use them regularly they come on.

Any ideas?

the map lights only operate using the buttons, they don't come on with the dome lights.

Well then that's good to know. Just assumed it was like the NBS. Thank you
