I have looked into the musty A/C vent smell issue for those of you having that problem (too much idle time after surgery.) It appears the origin of the smell is caused by fungus, bacteria and other microbes growing inside the evaporator core. This dark, moisture laden environment is very conducive to the growth of these organisms----makes sense. Ford and GM address the issue on a customer complaint basis only. Ford uses a Purge Module and GM an Electronic Evaporator Dryer (EED.)
These units, along with others available such as AirSept's, allow the blower motor to run after stopping and turning off your vehicle. This drys out the evaporator so the little critters can't grow. These units are expensive in my book, anywhere from $250 to $500. These modules have about 5 bucks worth of parts in it and are very easy to wire in. I'm looking into having some built overseas. It is a great concept, our house HVAC uses a system sort of like this, but it will not work on vehicles equipped with Automatic Temperature Control.
A quick fix that will last a month or two is to turn your A/C on outside air (off of Max Air,) turn your blower motor on high and spray a lot (1/3 can) of Lysol into the passenger side cowl area in front of your windshield.
After about 5 minutes, turn your A/C control to Max Air and allow to circulate inside the car for 10 minutes. She'll smell fresh as new.
