Re: Sour smell from air conditioner

So their plan today was to spray that stuff in the air box. Manager says he contacted a tech with Jeep and they make them go through different steps. First step is the spray. We drove it around for about 20 minutes tonight and could already smell the funk coming back.

The issue with the hoses mentioned above impacts Chargers and Challengers, so it is possible it's related. Or else there's just a design flaw. If anyone else is having this issue, please bring it up the next time you go in. Squeaky wheel and all...

Re: Sour smell from air conditioner

I'm pretty frustrated with the HVAC design. I cannot control when the a/c runs unless I take it out of auto. Every other vehicle I've owned has let me control the a/c independent of Auto setting. This makes really hard for me to turn the a/c off a few miles from home and dry off the coils. Nothing grows mold better than damp a/c coils in a warm garage. We get a funky smell in our AC as well. I changed the pollen filter and unfortunately the smell was still there. I don't like to spray perfumes because they trigger my allergies, but I have tried AC fresh in another vehicle. The trick is spraying the coils...

Agreed. I'm not a fan of the auto settings at all. Not sure why it always feels the need to run at such a high blower setting but if you change anything it turns auto off.

Hey Neighbor!

Just an FYI. I used the AC two days ago when we got hit by the heat wave and there was no smell. Also, I have never used the "auto" feature since I never liked the way it worked.

Which year and color is your WK2?

Cheers,

Yeah the weather has been a little skitzo latey. I may try avoiding the auto setting and see if that helps.

We have an all black '15 Altitude. There are a couple of them running around but ours is the one with KO2s (awesome tires btw) and HIDs.

I'm experiencing this as well, has been an issue since new. I think step 1 the dealership wants to try is filter replacement.

My smell is a really nasty mildew/stale air combination that's the most musty smell i've had from a vehicle that had working AC. My wife's 2002 Acura is pristine compared to this... very disappointed that the issue persists.

For what it's worth, even with independent controls, most modern systems will still utilize the AC system to control humidity even when the AC is turned off.

My F150 did that and I never had any issues with mold or smells, even after several years of parking in a humid, hot garage in the summer.

If you're having issues with mold and/or smells, that's a design specific issue. Otherwise, every vehicle made in the last decade would have the problem.

For what it's worth, I haven't noticed any smells in my Jeep.

This I agree with.

It seems like the vehicle has no idea there are low settings for everything, including the heated seats. The result is, everything comes on in high mode, regardless of need.

Re: Sour smell from air conditioner

I'm having the same issue, every time I turn on the a/c there's a surge of foul odour, after it runs for a bit the smell goes away.

Check for rotting leaves or debris on exterior hvac air intake, these vents are in the left rear quadrant(passenger side) under the hood. Mine gets build up of leaves on there sometimes, when they get wet or rot they can smell. Also the charcoal version of the hvac filter can help with minor smells. Jeep comes with non charcoal filter so the charcoal one is worth a try when troubleshooting but not a cure for dead animals in the system.

My 2014 was doing that any they did some kind of a star case. They cleaned the evaporator and put some special coating on the coils. Not sure what all else they did but the smell has been gone for a few months.

Re: Sour smell from air conditioner

I checked for leaves/debris, nothing there.

I'm gonna get a charcoal filter and if that doesn't work.. maybe bomb the HVAC system with Lysol.

I was able to have my vent system cleaned by the dealer... they had a machine that they used which made it smell like old man for a couple of days but after that the smell is gone. They had planned to replace just the filter but left the old filter out to try and make it better while they waited for the replacement.. but it still stank and I let the service manager smell. He agreed.. got the machine to clean and so far so good!!!
That was probably a month ago.
