i am trying to bring a 2004 deville back from the brink of death. i'm having a few issues i'm dealing with. 1. all cigarette lighters do not work, although all the fuses are good. 2. all of the heated and cooled seats do not work. it started with the drivers side then they all went out. 3. the drivers side mirror doesn't turn downward when the car is shifted into reverse. just 3 for now. more to come as i get deeper into it. any help would be appreciated.
