I think there is some mold growing in my A/C vents from the moisture. Its causing a pretty nasty smell in my car and i'm wondering if there is any way to get rid of it? I've tried turning on the A/C and spraying disinfectant spray into the outside vents, that didnt work. Could it possibly be the drain tube that is blocked? If so, how can i unblock that. thanks for the help.

DESCRIPTION
A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. "Mazda Air Cooling Coil Coating" is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years.
NOTE :See parts information for Mazda Air Cooling Coil Coating and Kit part numbers.
This treatment provides a durable coating that will aid to prevent biological reactions that lead to odor concerns. It is applied to the evaporator in a misted form that is introduced by way of the recirculate door, the blower motor resistor access, or the blower motor air intake (on rear a/c only). Proper application requires the evaporator.
^ Surface to be relatively clean and free of leaves, dust build-up and debris.
^ To be thoroughly dried, and the product cured onto it after application.
NOTE :
^ A/C odor is not unique to Mazda vehicles as it will occur in other makes and models.
^ To minimize A/C odor, inform customers of the following suggestions:
^ Keep the cooling unit dry by leaving the blower fan ON (at least on low), even if the A/C is not being used.
^ In low humidity (dry) conditions, keep the ventilation system in the "FRESH" mode all the time, or as much as possible.
^ In high humidity conditions, or if the air has a lot of dust or pollen, keep the system in the "RECIRCULATION" mode.
^ A few minutes before reaching a destination, turn the A/C OFF, but leave the blower fan ON. This stops the accumulation of condensation on the evaporator/cooling unit, and it helps dry the inside of the cooling unit.
Customers having this concern should have their vehicle repaired using the following procedure.

Dry the evaporator using the following procedure:
WARNING : Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss of consciousness or even death could occur. Don't run the engine when inside an enclosed area.
A. Start engine.
B. Set HVAC controls as follows.
^ RECIRCULATE
^ FULL HEAT
^ FAN HIGH
^ A/C OFF
^ AIRFLOW (FACE)
C. Open one window approximately II.
D. Let engine run for 10 minutes.
2. Remove glove box by:
A. Pushing top stops inward (plastic will flex).
B. At left side hinge, lift clip out of its seat.
C. Pull right axle pin out towards left side and remove glove box.
3. Stop engine. Switch OFF fan motor.
4. Remove fan resistor and inspect evaporator for debris; remove debris using an appropriate vacuum cleaner
WARNING : Blower motor resistor may be extremely hot.
5. Reinstall fan resistor.
6. Shake bottle of Mazda Air Cooling Coil Coating well and attach it to applicator. Then connect applicator to compressed shop air.
7. Insert applicator in grille of recirculation door. Point nozzle tip in direction of evaporator.
8. Switch fan motor ON.
9. Begin spraying by gently moving nozzle tip in front of the evaporator surface. Spray entire contents of bottle in short bursts, 3 seconds ON, 3 seconds OFF onto evaporator. A fine mist may exit from ducts.
10. When bottle is empty, switch fan motor off, and remove applicator. Turn engine off and let vehicle sit for 10 minutes.
NOTE :For reuse, clean the applicator by flushing a bottle of clean water through it.
11. Reinstall glove box.
12. Use STEP 1 to dry and cure product.
13. Note application date in service record.
