Or it may not have a filter, either way, dump a can of LYSOL through the HVAC via the opening for the filter, and let if coat the evaporator core. Do this out side with windows & doors open, LYSOL has a tendency to be overpowering to the senses.

Or, if the cleaner hose is small enough, use it without the crevice tool to suck up any big, bad stuff. Also, make sure the condensate drain for the air conditioner isn't plugged with dirt. If the water can't drain well, it will cause a moldy smell and may overflow onto the carpet inside the car.

I used some commercial "NO RINSE" evaporator coil cleaner I had on hand to clean my home's Central A/C evaporator coil. There was no filter but there was a small amount of "aged dead tree debris" which I was able to vacuum out before cleaning coil as per the directions on cleaner! The fact I no longer have to see that pained look on my wife's face or hear the repetitive complaint about the smell from the A/C vents any longer "Priceless". Thanks for your help!
