How to get rid of musty smell in A/C?

Use a product called Freshana Organic Solutions Air Purifier. Works wonders. Just spray it in the intake vents while it's running and it will clean it right out!

This same think happened to my daughter's car. I researched it and came up with putting Lysol spray in the intake vents while it is running. You can find a video of how to do it on youtube (which will say how long and how much to spray) but don't put "Hummer" in the search criteria because it can happen in most vehicles so don't limit yourself to the response by putting Hummer. The responses also said the smell is from a mold which happens when you use the air conditioner circulation button too much and leave it on too often. Good luck. ..

If you can remember to turn off the AC a couple of minutes before you shut off the car it can reduce the amount of condensation in the system.
