I have a 08 Chevy 2500HD diesel, and I know that when the trailer is plugged in to the truck plug, you have to have the tow/haul button pushed on the end of the shifter. Otherwise, the charge wire in the 7 round plug isn't working.
something has to be wired wrong on your truck. The constant power for the "charge wire" is wired direct to a lug on the fuse block. This has to be done when the truck is new. GM just tapes it up under the master cylinder. If you're not getting power unless tow/haul mode is, something is definitely wrong with your truck.
And I have a lot of experience with Duramax trucks from 06 - 14.
yep; the 2nd responder is correct; the "charge wire" isn't connected to anything other then the lug on the fuse block
Well, I'll be damned. I didn't get a manual with my truck when I bought it, but I did look it up. The online manual said that's the way it had to be. I really didn't care which way it charged or not. I had a 15,000lb (supposedly) loaded toy hauler. So tow/haul was always on when I was pulling it.
Thanks for the correct info, I'm still wanting a manual for this truck. Oh well, it's about out of the stable any way, no more trailer, no more big truck needed......
