Check your heater hose first. If both are hot, it is probably a blend door problem. If just one is hot flush the heater core.

Sounds like a blend door issue to me. Have auto HVAC or manual?

auto HVAC. seems like its going in an out possibly and just taking a while to heat up.
Blend doors on these things can be a pain. My recirc door has been messed up for a couple of years now. Just haven't taken the time to fix it. Do some googling of gm blend door and see if that leads you to anything.

No, that's not a banana in my pants.
Sounds like the blend door. Mine gets stuck on hot fairly often but I still have not bothered to fix it because if I shut off the truck and wait long enough, it will eventually move back to cold. If and when it gets permanently stuck, then I will have to fix it.
