2023 Peterbuilt 579 Dashboard AC, radio and 12v lighter outlets are off

It could be a warranty issue, bring it to the dealer to have them fix it.

 

When you turn on the key, let it sit until every single check light goes out, then, start the truck.

Our fleet has three T680 1st Gens doing this, I’ve found so far. Not having A/C is a regular deal for mine. When I start it in the morning and I have A/C, the truck gets idled all day. I surmised to the techs it’s a body control module (BCM) issue. They agree. But, with no diagnostic path to follow, they won’t try anything to fix it. If the HQ building didn’t have A/C, every possible part would be thrown at their A/C system. Pitiful.

 

If it has less than 100k miles on it take it to the dealer and let them figure it out. Could have a cab computer that needs an update.
