2021 F350, 12k miles. When just running the "vent" and not AC there is a mildew smell......any ideas where it is coming from/the cause? It is under warranty I just cringe every time I have to take it in.

Thanks.

So I took it to the dealership and they found moisture in the cabin air filter compartment. Not sure how that happened...car washes maybe?

could you have a drain line plugged?
It finally registered what you meant.....the condensation drain line? I think so, I ran it on max AC for 5 minutes parked and no condensation drips.

Sending a late reply.....I crawled under and jabbed a twisted piece of tie wire up the drain tube.....5 minutes later a big puddle under my truck. THANKS!
