Damp A/C smell
How do you go about cleaning the ducts for the A/C when you get the "Damp Smell" when turning on the A/C? My car is a 2003 and the drain hose is clean on that side of the car, and the 3 on the drivers side are also clear

From The GM manual
Service InformationSome suggestions :
First, spray Lysol directly into the vent area outside your car where the windshield wiper is. This will help to kill the bacteria that is causing this smell. I was also told to make sure to run the a/c using outside air first, for the first 2 miles. Then, you can revert to the inside circulation which provides a stronger rush of air.
