'02 Z71 Tahoe illuminated entry problems

Have a 02 tahoe, and when i open the doors the interior lights do not come on, but i can press the individual light button and they will work. I have a dome override switch and not the door pegs that trigger them to come on when a door opens. i have checked all fuses that i know to check and i am completely stumped, but i do know it is aggrevating to have them not work. there are also courtesy lights under the mirrors that do not work and i'm thinking they are related in the wiring system. would greatly appreciate some knowledge if you don't mind. I welcome any ideas. Thanks
