My Blazers dome light, lights under the dash, and rear hatch will not work after I replaced my radio, Dash lights, overhead display, and other lights work on the inside so that pretty much rules out the fuses, (Checked the fuses that would make sense).

Today we tore the dash back apart to look for another wire, but couldn't find anything wrong, There was a purple and white wire behind the radio cut, but I am 99% sure that was to rear speakers, it was a dead wire aswell.

When I try to unlock the rear hatch no noise is made so its not getting power, and it all worked before fixed the radio.
