'06 2500HD Aux Power Socket Dies - Fuse Okay, No Ground

    The title kinda says it all. My dashboard aux power socket died during Monday's New England storm. My 9 amp mini-lightbar had been plugged into it. Suddenly... no more rotating lights.

    The aux power fuse is okay and the socket's center pin is still +12V hot... but the socket's outer rim... which should be grounded... is not grounded. :confused:

    My cigar lighter socket was already dead as a doornail from a mysterious and totally unexplained blown fuse. I have never once used the cigar lighter.

    My research here and elsewhere on the Internet shows that this entire odd set of circumstances is actually quite common in Chevy & GM trucks. The phenomena is well known... but the actual solution to the ungrounded aux power socket has never been published (other than conceptually... i.e., "find the bad ground and fix it").

    My local Chevy dealership is so useless it hurts. A bird turd on my hood is both smarter and more useful. :angry:

    Anyone have any hints or experience about where this bad ground may be occurring... or how to get the dashboard apart (or the aux power socket apart) to attach a brand new ground???

    I blew my cig lighter the first storm with my lightbar on it. I have used my aux ever since, but there is no blown fuse for the cig. I dont know what the deal is???

    Mine is at the dealer right now for a Check Engine Light and the AuX Power stoped working.
    I will let you know what they changed or did!

    I had the same thing happen to me. It worked when I got my mini bar (only plugged it in to play with it) and 1st time I plowed it stopped working. Checked the fuse, it was good, so I have no idea.

    Check the socket itself. I remember on some of the older ones there was a ceramic "fuse" built into the housing itself. I don't remember if it was on the ground side, though.

    Sounds like a similar "no ground" problem... only on the cigar lighter socket. I'd love to see the arrangement behind that dash to be able to understand how these sockets were intended to be grounded... and where GM's plan is breaking down. :(

    Thanks Jason. I sincerely hope the two issues are not related. That could mean that mine is a bigger problem than a mere loose ground.

    Yep... sounds like another lost ground.
    Seems unlikely... but so does losing ground in the first place! :eek:

    The big question is... how do I get that socket out of there to check it? I can't seem to access it from the rear nor pull it out from the front.

    The useless Chevy dealer near me had no clue. :(
