I am not sure it your car has a cabin air filter or not, but if it does then I would try and change it first. Does your car have a recirc position and fresh air positon on the controls, if so you may want to try turning the controls from the recirc to the fresh air position before you turn the car off. I had a honda that I left the controls in recirc all the time and noticed a foul odor coming from the vents when I would turn it on. I found that some moisture was standing inside causing the odor. I started turning the controls to fresh air a minute or so before getting home and within a couple of weeks the odors stopped. Another option is that you may have some mold that has starter on the ac evap coil and short of having your ac discharged and removing and cleaning it you may try so lysol or ozium sprays to try an kill or neutralize them.
