negative. only has a cb radio, and trailer brakes. disconnected both and tried again. even disconnected both batteries hoping something would reset and nothing.

trailer brake is a likely issue, make sure it is fully disconnected from the factory harness, not just 12V.

Thanks

I hate to keep saying this, but there has to be something wired up inthe truck, that did not come from GM, that is causing this issue..try pulling fuses?
