2020 A/C stinks
My 11000 mile A/C smells really bad when i first start it and I have looked everywhere for wet spots in the cab and nothing... the smell is definitely coming from the a/c..Any ideas???

Manually control the system and take it out of recirculation mode. It's a good idea to do this whenever you park for the night. The reason to do this is that it opens the plenum to circulating outside air so that you inhibit the favorable mold and mildew environment. You can also spray Lysol into the HVAC air intake to kill the mold and mildew.

This truck probably hasnt missed a day running since I bought it mid January... I have changed cabin filter and also tried the lysol trick but didnt do a follow up yet like some of the videos say might be necessary.
Just really dont wanna take it to a dealer right now with all this other crap going on and im really busy now too. so im gonna figure it out somehow

try something like this....
https://shop.advanceautoparts.com/p/...ir%20freshener
I am a smoker and I refresh my vehicles with a whole car can like this.... usually use Ozium.
works like a bug bomb... AC on high recirc and you pop can, close doors and it fogs the entire vehicle, then you open the doors air it out
might need 2 cans going on a crewcab or do it twice.... I also spray my cabin filter with fabreeze

Get an ozone generator and place it in the truck with your fan on recirc and on high - let it run for 1 hour - stay away from the truck and be careful when opening the doors - let it air out before getting in. It will remove any current odor, but you will have to figure out what causes it to developer the odor. Do not run the truck in a garage when doing this .... I got an Ozone generator for $50 and have used it on several cars/trucks with 100% success.
Got mine on Woot but they are not in stock there now. Here is the exact same one at Amazon ...

Move to a less humid environment. 
A few minutes before reaching my destination I turn off the A/C, keeping the fan on, and make sure it isn't on recirculate. This eliminates the startup stink for me.

I had 600 miles on my 2020 and just took a road trip of 500+ miles. Great weather no rain but used full tank of washer fluid with all those stupid love bugs in Florida. Cleaning out the truck I noticed the driver side floor soaking wet. Wonder if this has anything in common with this mold smelling issue? Going to try and use no A/C for a few days and see if it stays dry.
