Rear acess door open stays on 2003 GMC yukon

Rear access stays on in DIC. dome light stays on have to override it. Horn does not blow when lock or unlock. Rear wiper will not work. I have change rear latches one on each side of door on bottom the one in middle. Is there a reset for the remote? Is there door senor somewhere? On old cars there was a button that turned the dome off. How does the newer cars tell the doors are closed? Can not find a fuse for this. I will be very thankful for any help you may give me .I have tried everything I know THANK YOU
