Had enough with the mildew smell when AC kicks in. Bought a can of Frigi-fresh and ready to spray that sheet! I think there's one intake for fresh air below the windshield I can spray on the outside, what about interior area? The blower fan is located on the passenger side where I can spray around. Would there be any other interior intake I can spray and clean it out?

I pulled up a schematic and notice the evap core is located right next the indoor air cabin filter, I am think taking out the filter and spray directly into the slot where filter sits, any chance of shorting anything out?

 

So, got Frigi-fresh, sprayed the living daylight out all intake and outlet vents. It works pretty well, 95% mildewy smell is gone. If I have to do it all over again, I would save the money from amazon the spray and get Lysol spray as the active is identical-Benzylalkonium Chloride!

 

As a final smell remover, thought it masks the real issue, get a charcoal cabin filter.
