    2003 Chevy Tahoe - 7way brown wire not working - HELP

    been fighting this... i just got this vehicle recently... i know the trailer lights are fine because when i plug into my other vehicle the trailer lights up fine and i checked and the 7way plug in that vehicle has same wiring model as this truck. The flashers work, the blinkers work, the break lights work... everything... but the running lights ( the brown wire ) is not feeding me power.

    Does anyone have ideas that has any CHevy experience ? I checked fuses and they seem fine but i didn't check every one.... all the lights are fine on the truck.
    Help.

    I figured it out.. Posting it here in case others have this issue. In the Chevrolet Tahoe and i'm told other Chevrolet 1500 series trucks there is a fuse box under the front hood and in tha box is a 15A fuse in the uppper left corner. It was blown. I replaced it and my tail lights worked fine. I found this out after i reconnected my ground on my trailer and on my truck.. at least i have great ground connections for the season!

    2004 Chevy 2500 crew cab Silverado.

    NO POWER ON THE GREEN WIRE IN THE TRUCK TOW HARNESS BEFORE THE 7-PIN ROUND RECEPTICAL.

    recommendation #1 for you JAZII... go hookup someone elses truck to your trailer to see if the issue is in the trailer or truck.. ensure that it *is* in the truck wiring.

    I know for sure it is the truck. I tested the truck receptical with a mutimeter, no power to the green wire, which is the right turn and stop wire.

    I did not get a chance to look at the truck fuses today.
