STANDARD PROCEDURE - A/C EVAPORATOR CLEANING

Some vehicle operators may experience a musty odor from the A/C system, primarily at start up in hot and humid climates. This odor may be the result of microbial growth on the cooling coil...

My a/c has been really musty and sour smelling for the past several thousand miles. I changed the cabin air filter myself, sprayed Lysol into the intake, and it still stinks. I took it to my dealership hoping they'd go through the above process but they said that to look at the cooling coil they'd have to remove the dashboard so they didn't want to do it. I can't say I'm reassured that I'm not breathing in toxic air.

I hope I don't get lung disease and can't make a living any more, because that would be really bad.

Mine has been stinky at times causing me to caugh, especially when the ESS is active. When I'm ready to take it in I'll contact jeepcares and just let that team handle it.

Good idea. I may have to do the same. The dealership couldn't fix my squeaky brake pedal either, even though another forum member had the same problem and had it fixed at the same dealership. All I got was the dreaded "normal operation."

Then followed the instructions on the can for the Vents with no filter. Might be worth a try if your Dealer won't do it under Warranty.
Do you have any reference pics or anything? Mine is musty, and I'd love to learn and just do this myself.

If they would just read the recommended procedure and follow it to the letter, it does work. No Dash removal, only the Blower Motor for access.

Let's just say I've been underwhelmed by my dealership experience since the date of purchase. I like the vehicle well enough but I can't see myself staying with the brand. I've bought three vehicles from our Audi/BMW/Porsche/VW dealership and they've set the customer service bar pretty high.

Absolutely the system must be cleaned thoroughly or the problem could return.
All mold and mold spores must be removed during the cleaning. There are very few products that will kill the spores themselves.
This is especially important for people with allergies to mold or in the rare instance that it could be Black mold which is highly toxic.
In some cases it might be advisable to send a sample in for testing.

The problem is that when the filter gets dirty it filters less air. The dirtier it gets the less it filters.
That causes a loss of air flow through the system. That is real bad when it happens.
That leads to mold in the condenser unit and elsewhere which is now lacking air flow and increased humidity.
Mold causes the smell. Mold needs several things to exist.
* Food, that is any organic matter like dirt/dust.
* Lack of air flow
* Relative humidity of 70% or higher.
* Temperature, that is generally what we humans enjoy. Below freezing it does not grow but will grow if it warms. Warmer the faster.
Mold is everywhere in our environment but can only exist in the above conditions. HVAC systems are prime candidates for this issue.

About the only way that can happen in our cooling system, short of a backed up drain hole, is the filter not doing its job.
The dirtier that filter gets the less air flow you get. A lack of air flow is the most likely reason for the smell which is being caused by the mold.
A new filter may help because the increased air flow will stop the mold growth from continuing. But any existing mold just goes dormant till the next opportunity to grow.

Cabin Air Filters should be changed depending on use and individual circumstances. Recommended maintenance for that filter (20,000 miles) is too long in some cases in my opinion.
Mine at 2 years and 14,000 was dirty and thus impeding air flow and raising humidity levels in the system. A good quality filter will catch more than dirt. It will catch mold spores and keep them from circulating in your Cherokee. If the filter itself gets moist from a lack of air flow you could have mold on the filter itself.
I will change mine every 12 months from now on. I now have a sticker on the Cabin air filter panel reminding me its there with the date.

Chrysler has a manufacture defect causing mold to grow in the A/C evaporator (according to the dealer) ask the dealer to research Star Case #S1324000018. Witness when they remove your ac evaporator to clean the mold, and take pictures. Breathing toxic mold spores can make you very sick, these are biotoxins that will enter your body.

I was hoping my moldy smell would magically disappear over the winter but it hasn't so I want to use the Kool It. Does anyone have a photo of the drain plug location?
