Terrible smell in my Cabin

Ihave a 2004 Camry and during the summer months when I use my A/C a very bad odor comes into the car when I turn it off and use ony the fan. I changed the cabin filter that s in the glove compartment ans look to see that the condensate is dripping from under the car. Whats my next step?

Generally I would suggest buying a can of Lysol or like product at the grocery store or a product made for cars at the auto parts store. Then open the hood and take a good look at the area under the vents in front of the windscreen. Makes sure it is clean and drains properly. Then turn the fan on high (not recycle) and start spraying that can where the air is being drawn in.

What position do you leave the AC controls in when you park the car?
