2000 LS NO POWER TO AC/HEAT controller

[Cassious]

hey all,
I have a 2000 Regal LS with the dual ac. My heater was working on and off, but latley is been off...so i figured i should start with the fuses...fuses are fine on the door and under the hood, and by fuses i mean all the colored ones. so then i went and got a new controller. and still nothin. i dont have any idea about what relay or if there is a fuse or somethin that im overlooking bc of the the names on the fuse list. the thing thats strange is that my cigarette lighter stopped working too. so im at a loss right now as to what else to do. Im in illinois, and the winters out here make hell look like a vacation spot. so any help would be greatly appreciated.

Did you check for voltage at the respective fuse sockets? You could have no voltage (12 volts) even though the fuse(s) is good which may take you back to a wiring or possible ignition switch issue.
