I'd make a joke out of having loose women inside the vehicle at various times.............but..........it clearly doesn't work with you.

Your solution is as follows:

Get a commercial spray bottle and fill it 1/2 way with clorox bleach. Fill the remainder with water.

Turn the blower on high in the economy mode with the temperature wheel dialed all the way to full cold.

Spray at least half the contents of the bottle into the cowl intakes. The chlorine will kill all the mold and mildew that have accumulated in the vent system. I'd leave the doors open for a few hours to get the vehicle fully aired out.

Should be good for about one year.........then you'll have to do it again.
