Light on

Maybe the door switch is bad.

Were is dooor switch located

Unless you can see on on the door or door jamb it is integrated with the door latch.

Isn't that the wat it's supposed to work? Override switch in one position makes the interior lights stay on, in the other position they come on with the door switches. There may be 2 fuses for those lights marked like dome and courtesy or interior. I hope this helps.
