musty smell after turn off AC...

[MilehighRam]

Noticed mine isnt draining, and I have the funky smell too.

I'm going to look for the drain; mine doesn't leave much of the telltale water when parked and the musty smell is pretty bad sometimes; most often after eTorque

Anyone find a fix for this? 2019 Ram 1500 with 17k miles. Stank smell every time I start the truck but it goes away after a few minutes. I’m in hot Arizona and AC is on full blast when I start it up.
I see talk of cabin filter change and unclogging AC drain but no one is saying that fixed the problem here.

I’m also having the same issue here in San Diego. I just purchased my ram about two weeks ago and I started noticing the smell over the last 5 days or so. I replaced the cabin air filter which I advise doing but the smell is still there. I’m going to call the dealer in the morning and get them on this issue and I’ll get back to you guys with a solution as soon as I can.

Because the truck is so new and the time of year I can't believe the air conditioner has been used much. Did this vehicle sit on the dealers lot for a while? It's possible that a water leak elsewhere is causing a problem.

Bumping yet again to see if anyone has a solution for this. My truck is 4 months old and has had this smell for the past couple of months.

It is very present when the truck shuts down the engine with the autostart/stop and goes away once the truck gets moving again.

It kind of smells like vinegar. Recirc is off btw.

Ive had my truck since november of 2019 and still no fix. Had it at the dealership a few weeks back for some minor issues, this being one, and the only one they didnt fix. My ghetto fix is to make sure I turn off the start/stop feature in the summer so i dont smell it. Fortunatly the weather in CO is nice and this doesnt need to be done much. If I still lived in FL, i'd be livid.

I had this issue in my 2019 Lonestar. I bought an ozone machine off of Amazon for $50 and ran it in my truck with the air on recirc for 30 mins and that seemed to clear it up. Might be worth a shot for others too.

You may not notice any dampness on your floor. It could be the condensation drains in your AC system, and the moisture is staying inside AC unit, hence the moldy smell when you turn on the fan.

Whats the fix for this?

 

[LeadWolf]

I'm stirring this post up as well. My 6 week old Limited has a bad smell coming from the vents. Usually occurs when the engine stops and the AC is still running. Smell seems to reduce when the truck starts back up.

So this is sounding pretty common. 2021 Limited with 4.5K and same problem. When A/C first comes on or just turns off we are smelling the moldy musty smell. Also when Etorque kicks back in from stopping. Very frustrating. Has anyone had any luck before I take the dash off?

I’ve got a 2020 that I bought last May. It had a musky smell after about a week. It took 5 visits to the dealer before they were able to replicate it. I got lucky in that they covered an $800 procedure to decontaminant the evaporator. That was at the tail end of the warmer months last year, and there were no issues for the short time I still used the A/C.
Fast forward to the last month - I’ve been lightly using the A/C recently and could smell it coming back, while hoping it wouldn’t get any worse. But, I just used the A/C extensively for the first time this year and it was awful.

I just saw the TSB for A/C performance. It sounds like the HVAC got overhauled and am hoping that will also fix the rancid smell. I also notice my system will randomly push warm air for a minute or two (along with taking forever to cool down), even after being on the road for a while. I’m cautiously optimistic that the problems are linked and the TSB will fix it.

I get the vinegar smell in my Ram too.
My old F150 had it, as well as my wife's Infiniti.

Did the Lysol spray in the cowling on the Ford. Not too keen to try it on the brand new Ram. I figure its just a function of living in such a humid environment, but if I could get rid of it, I'd be happy.

Well I live in San Diego and it’s not very humid here and it was even happening during the winter after having the dealership try to fix it twice. Flushed the system and I changed the cabin air filter but it seemed to have gone away after the flush for about a few days and it was right back. Weird thing is that it goes away and comes back.

If you turn off you A/C before you turn off engine , approx 3 minutes before , this will help with getting rid of the smell when using the A/C. Mine is a non E torque model. And I live in Florida.
