    That doesn't seem like a fix to me. More like a cover.

    Hey you moldy AC people. Here is a product that may help. It looks like its made in Germany and for professional use specifically to kill stuff that grows on the AC condenser. I don't have any experience with this but thought it may benefit some folks here. Check out the product description and reviews on Amazon. This could be a way to mitigate the problem. Please report back if this works. Good luck.

    Einszett Klima Cleaner
    "A professional air conditioner cleaner that effectively removes odors caused by mold, fungus, pollen, nicotine and dust. While other products mask odors, Klima-Cleaner uses active foam to directly clean and remove odor causing agents from the evaporator core of the air conditioner system for fresh and clean air that lasts for months. Klima-Cleaner is applied by removing the blower fan and inserting the supplied spray tube through the intake vent which leads directly to the evaporator. For best results, apply every 3-6 months. Klima-Cleaner is water-based and does not contain any harsh chemicals. Recommended for professional application only. On certain vehicle makes, damage may occur if product is not applied properly. If uncertain about application, have a certified mechanic apply product or use einszett 911104 Klima-Cleaner Easy-To-Use (ETU) which doesn't require any disassembly."

    Re: Moldy AC - opinions please

    I've had the HVAC update, but the blower doesn't run after the car is shut off. Perhaps, one has to ask for this?
    Anyway, as I've seen several utube videos (eg, http://www.youtube.com/watch?v=CzYlp9dm7AI) from "professionals" who recommend blowing a Lysol type product into the external cabin air intake ducts, I'm thinking that although this is temporary, it does seem to work. However, before I use Lysol, I'd first like to know if Lysol will do any damage to the parts it comes in contact with? Yeah, I know this is temporary relief, but what the hell, it is an easy enough workaround.

    A fix is found!

    Making this a separate post. Had to speak to my dealership's GM about an insurance policy problem, and then asked him for the skinny on the stinky AC issue. He said that his dealership had found the fix, and their fix was adopted by Caddy. Although the fix was already mentioned in this thread (catmando, #46), I'd like to re-inforce it: The drain hose is inserted too far into the condensate drain pan, not allowing all the condensate to drain. The dealership will adjust the drain hose to its proper length.

    When will this be rolled out into a TSB by GM for all other dealerships?

    I have no idea, but would suggest that you speak to your dealership about this fix. My dealership's GM definitely told me that Caddy was adopting his fix.

    Cadillac dealerships all have a repair bulletin for this. Call them and make a service appointment and they will fix it. Had mine done this past summer. Call them and they know exactly what to do to fix it. There is no mystery to solve here.

    I've checked the TSBs and the only one that addresses this issues has them use the spray that kills the mold/smell. Do you know the TSB #?

    Yeah, spraying is a quick, but a very temporary and potentially harmful fix for the smell issue. I say harmful because the spraying most likely doesn't get everything (probably unless you spray weekly, a definite PITA) and eventually there will be a build up of bacteria and mold that can reach unhealthy levels. I say if you have the smell, don't wait, have faith in the tranny/exhaust fix...if you trust your dealership to do the job right.

    Bulletin# 99-01-39-004D. Paperwork states "a/c drain misalignment, pulled carpet back, check the drain as per bulletin, realign drain as per bulletin, for this complaint deodorize the hvac box with part# 12377952 as per bulletin# 99-01-39-004D."

    I think the hose gets fixed and then they spray to kill what has already grown in there.

    I just bought my ATS in September and I noticed a moldy smell this week. Way to soon to have issues such as this.

    I believe PIC5730 is the repair bulletin that addresses the drain hose. There is also a change to the logic to allow the blower to run to dry out the drain pan after the car stops. It will come on about ten minutes after the car is turned off and run for five minutes or so. These two fixes should take care of the problem in most cases. To fix the drain hose properly, the culprit should be replaced with part number 2312009, not just rearrange the original hose.
