The wife's 2000 GLE has a serious mold/mildew problem in the AC system. Anyone ever have this severe of a problem that it needed to be cleaned professionally? I have read all of the posts and tried everything - Lysol, bleach water, some foaming coil cleaner - and nothing is getting rid of the problem. I drive the car for 30 minutes and am weezing and coughing.

Let me know if you had any luck with professional products or a service performed by a shop.

Like I said, I tried all of the basic DIY remedies and there is no cabin filter. Looking for advice on professional services.

Thanks.
