I turned on my AC on my 04 Acura T l yesterday since the weather was warm and i noticed a stinky musty smell from my AC. I did a search and looked at some postings and it seems alot of posting indicate to spray Lysol into the vents (NOT CENTER VENTS BECAUSE OF ECU)but i am not sure what vents they mean? Has any one tryed spraying Lysol in the vents with sucsess? It also mentions checking the drain pipe, where is it located at and what is the best way to unplug it? Anyone have pictures or diagrams of the vents or drain pip?

 

the simplest and easiest thing would be to change out your cabin air filter.
then, asses and move on from there
