Started with musty smell on A/C startup. Tried shooting Lysol down the air intake, and shutting A/C off (fan still on pulling air from outside) about 5min. from home to dry the evaporator and deprive the mold of moisture. No joy. Changed cabin filter and was surprised how much mold was on filter. That white strip on top is how white the filter is supposed to be! And that aint dust on the filter, it's mold! For comparison, the engine intake filter still looks brand new sitting next to the new one I bought. Car only has 9k mi. and one year old. $11 and change at local parts store, and lots of YouTube vids on how to. Good luck. Oh yeah, no more smell!
