All lights staying on.... 99 Blazer
 

Hello fellow blazer lovers. I recently recieved a 99 Chevy Blazer from a friend with a few issues. For some reason all the lights stay on with the key removed. This includes: Headlights, side marker lights, taillights, cluster lights, dome lights, and floor board lights. I have replace the headlight switch, bcm, checked all fuses, checked all light bulbs, checked rear hatch switch, replaced all door sensors, and checked a couple grounds. And sometimes my headlights do not want to work but at other times they will. Im at a lose at what to do next. Any and all suggestions would be greatly appreciated.
