Foul Smell A/C Brand New 2014

Actually is the performance of the AC/Heating working properly. If not you have a leak in a core some where.

It seems to be working fine. I know the smell of a leaking heater core. Been there done that so it's not that. I bet it's fungi build-up. I had the same issue but in a Vw and there's a spray that kills it off but being a new truck, it's just silly!!
