12V flex bed no power

[Kizyle]

Have you unplugged the drivers side pigtail and tested the passenger pigtail? Then the reverse? Do they work individually? I assume you have not hooked up any device to them yet? Those breakers may not be serviceable which means they have to be replaced???or if they reset then is possible the bcm has been told to ignore that Circuit until the dealer tech resets the error flag. I have no idea, sorry...

Unplugged the truck for 3 hours hoping it would solve it, no change

Dang...
I would like to know what happened. I would be for running a separate power supply since I would prefer 30 amp supply there. But would need it to be on switch (to savem battery). May be forced to have dealer or someone read the codes.

I would like to say thank you to everyone in this thread. According to the dealer it was a blown #34 fuse. I checked every fuse and don’t know how I missed it. Time to wire some lights up and see if it actually works now lol

I want to add, if you buy your plug adapters from Amazon, there is a chance the polarity is swapped. That was the case for mine and made it seem as if the 12v accessories had no power. Red was negative, black was positive. Check with a multimeter.
