So far this has been the second year I've had this issue. When I turn on or off the ac I get a moldy sour smell. After it runs for a few minutes it smells fresh. This is what I have done so far:
multiple cabin air filters
spraying Lysol threw behind the cabin filter
making sure the drain port above the transmission bell housing in not clogged
spray Kool ac foam cleaner 2 times through the air vents and dash defrost vent to clean the coils
Ozone deodorizer machine for 24 hrs
Kind of at my whits end here. We take my wife car most of the time because my challenger stinks and it bums me out not to drive it.
Does anyone have any Ideas?
You should run your a/c year round at least once every two weeks and for five minutes on high before storage, the last part being straight from the Owner's Manual.
