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.

I had a "smell" in mine also. I used Turtle Wax deodorizer and it was gone. Now I make sure I turn off the AC a few minutes before I shut down for the day. My guess is the wet coil gets funky if it's wet and left off for several days.

I personally find internal humidity to be more offensive.
That's why I drink plenty of bourbon. Keeps the internal humidity down.

Have you checked the passenger side carpet? I had that smell too. It ended up the carpet was wet and the water was condensation from the a/c. There is a pipe under the glove box against the firewall had condensation around it. Took it to ford 3 times they could never fix it completely. Good luck.

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.
