The interior lights ,cigarette lighters, and the power mirrors do not work on the inside of my '97 sts Seville. The courtesy lights, dash lights, and every thing else on the interior works though. I checked EVERY single fuse under the hood and in the trunk and i made sure that it was getting power on both sides. I'm thinking maybe a connection is loose in the wiring harness or maybe where they split off in the car. Anyone have any ideas or possibly the schematics of a 1997 cadillac seville sts.
