    Default 12V power outlet looses power

    I own a 2001 Suburban, and the accessory 12V outlets all quit working earlier this week, this han never happened before and yes i have checked fuses in the dash
    the one in the back also will not work, but everything else, the radio, lights, A/C all work
    any ideas??

    I would say you'll need to start popping some trim off and start power tracing. I don't have access to a wiring diagram.
    Multi-meter, test light, and assorted screw drivers. And a whole lot of patients.

    Were both outlets on the same fuse? Seems that they would have separate fuses since power draw can be as high as 20amps. Pull the fuse and with a test light you should see power on one side or the other of the fuse connection at the box. If you don't have power there is something wrong with the power coming into the box for that circuit. If you do have power you need to start tracing the wires towards the power outlets to see where you are loosing power.

    btw, I lost power on my 93 burb. I dug under the dash and found out that the plug on the rear of the accessory outlet had come loose. Must have been all the banging around when I four wheel!
