Terrible musty odor coming from the Defrost vents. Thought it was wet blanket in the back from the beach, or floor mats. Cleaned and shampood them, no change. When I turn the air on it blasts the smell in your face.
Where do I get the cleaner/disinfectant, and where do I spray it to get it into the system.

We've got a musty/mildewy smell when the air con is on. Was going to replace the cabin filter but wasn't sure if that would fix it or not.

When starting car a horrible smell comes from the vents. It doesn't go away but it's less intense after a few minutes.

Bad oder coming from hvac system.
No smell in recirculate mode. Smell is more of a dried leaf and dirt smell, believe only way to get rid of it is to physically clean evaporator/heater core compartment.
Moldy/Mildew smell coming from HVAC system immediately upon start-up. Seems to happen in warmer temps (A/C?) although it has happened at times in the winter. Doesn't seem to smell in very frigid temps. Dealer can't "replicate" the problem so I'm going back and forth with them to do something without me having to take it in again when the problem is detected.
The musty odor is very strong with the air conditioner on. I had my van checked and they could not find the source. It was never corrected.
Musty odor in AC system in both warm and cold temperatures.
