'01 Suburban Interior Lights Off

I was installing an overhead DVD player into my Suburban and lost power to most of the interior lights. The under hood light, glove box light, cargo area light, door lights, reading lights, and dome lights will not work. I have checked all interior light and courtesy light fuses and can't find the problem. I have checked almost every fuse in both boxes and the relay. Any suggestions? Other than I shouldn't have been trying to install the DVD player myself. I allready get that from my wife. Thanks.

Did you hit the 'Dome Override' switch?

I tried that too, I just can't seem t find the problem. Do you think it might be a problem with the override switch?

I can't get any of he lights to come on. I don't think they're getting any power. It seems like it's a common fuse problem, but I just can't find the fuseor whatever the problem is. Any idea where the fuse for those lights is located?
