dead 12V outlets

(2003 Ford E450-based class C) All of 12V outlets are dead; one in the cab and two in the "house". I know that the cab and house outlets are on different circuits; I have checked the fuses in the cab and in the power center, and they appear to be good.

Is there a "hidden fuse" that I could be missing for the cab 12V? Or, any ideas on what else might be checked for the cab and the house outlets?

Thanks for any suggestions.

    Appear to be good? I assume you either do not have or do not know how to use a VOM? Get one, learn how to use it, and properly check the fuses.

    Cab may need to have ignition switch in the "on" position.
    Could have blown fuse next to starter relay on firewall next to chassis battery.
    Coach receptacles could have blown main fuse in 12 volt DC distribution panel.
    You are talking about the cigarette type outlets?
