2004 Ford F-350

My door open indicator light on my dash stays lit even with all the doors closed this is causing my cabs interior both front and backlights to stay on also my bed light on the rear of the cab also stays on continually.I have looked for fuses which may have been burnt they seem to be ok hard to tell though because I can't find any appropriate fuse in my manual for this problem.I've shut the door and made sure the protective rubber hoses where the door electrical feeds through are not kinked or visably damaged. The lights stay on with the truck running and when it's off. Any help would be welcomed
