BG Frigi-Clean is a product used to fix this on many cars. Available at specialty A/C repair shops. I've looked a several chain repair shops, that also do A/C services, but none here carry the product or offer the service. My 300M has this smell and I wanted to get it cleaned. It's a foam that's injected into the system and cleans the evap coil to eliminate the problem.
New TSB: A/C Cooling Coil Odor (300 and Magnum)
TSB#: 21-013-05
Date: Aug 04, 2005
Subject: A/C Cooling Coil Odor
Models: 2005-2006 300 and Magnum (+ many other DCX vehicles 1993-2006)
Overview: This bulletin involves inspecting for leaves and other foreign material, cleaning, and treating the cooling coil and housing.
Symptom/Condition: 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. During normal A/C system operation, condensation forms in and around the A/C cooling coil. When airborne pollutants mix with this condensation, bacteria and fungi growth begins and odor results.
Diagnosis: If the operator describes, or the technician experiences a musty odor when operating the A/C system, perform the appropriate Repair Procedure based on the vehicle model.

Note: This TSB involves extensive procedures too long to list here, the bulletin is 11-pages long. If you need a copy of the bulletin PM me your email address.
