Horrible Smell coming from The AC

[Big2019Ram]

Has anyone noticed a dry Mildew smell coming from their vents once the Ac is turned on? I have really been noticing it being very strong lately, but only when the AC is Blowing.

I’ve had vehicles do that if I ran recirculate all the time.

Man the smell is breath taking

It's a known problem with new FCA vehicles.
I traded my 2018 Pacifica because of that and my Ram did the same thing pretty much since day 1.
I visit the dealer every few months for this reason.
I actually went to the dealer to address this today and scheduled an appointment for next Friday. I will probably have them re-charge the system and clean the AC radiator from bacteria.
When my service adviser smelled it his reaction was so funny "Dude, IT SMELLS LIKE BUTT", His words.
I think the system is undercharged from the factory and that's what causing this issue.
Will keep you posted.

Check your cabin filter, they get pretty bad in these 5th gens.

Nope..
Unfortunately, It has nothing to do with that.

I had a previous car with that problem. The A/C condensation drain was blocked and it smelled terrible. After that was cleaned, after a day or two it was back to normal. When I ran the A/C there was no "puddle" under the car which was an indication that the drain line was clogged. Just a thought.

Now the next question would be how to drain the A/C condensation?

Came here to post about this issue. I replace my filter with a NAPA gold filter. It didn't fix it, though the old one was disgusting.

I shoved about a foot of drip hose down my condenser drain, No luck.

Now the next question would be how to drain the A/C condensation?

It's the small hose poking out on your firewall on the passenger side. fairly close to the engine.

IT SMELLS SO BAD!!! I DON'T KNOW WHAT TO DO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This has been a problem for as long as they have been putting A/C in cars. There are methods for eliminating this. Here's one way...

How to Eliminate Odor from a Car Air Conditioner

If your car's AC smells musty, there's an easy fix If there is an odd, moldy smell that kicks in as soon as you turn your air conditioning on, you don't have to close your nose and bear it. More likely than not, you've built up some mold...

My VW golf had this problem really bad. I took it to the dealer under warranty and they cleaned it using ozone. I'd take it back to the dealer and have them clean it.

I have zero smells on my 2019

I’ve had this issue on a VW Atlas, most recently. Ended up learning that I need to turn off the climate system/fan when running through a car wash. The high-pressure water and vapor saturate the system internally, leading to this unbearable smell in a day or two.

Have not washed my truck for two weeks now. Smell still comes and goes... IDK... Doesn't look like this is the problem...

I have the same problem and these are some of the issues that I experienced and a couple of things that helped.

1. As someone said above, NEVER go through a car wash with the fans on. It sucks moisture into the system and then doesn't dry unless you go for a long drive.
2. Turn off your AC about 2-3 minutes before you get home and let it dry out the system.
3. My problem was that I back down a fairly steep driveway so the front of my truck is pointed up. In the summer, I just have to pull in and allow the drain to stay downhill. When I would back in I never had condensation puddles under the truck. But when I pull down the driveway, I now get a good cup or two of water that runs out.

Hope that helps!
