It is mildew. Pour chlorine bleach down the intake vents in front of the windshield (where the screens are) you should raise the hood to access them. When you are finished, (let it sit) rinse with water. Fluids SHOULD pour out of drain hose (poking thru the firewall) from the evaporater box under the dash. ***A cautionary note for using bleach, please make sure that you dilute the mixture with at least 50% water, and do not be in the vehicle if the system is running or shortly after applying the bleach (bleach is obviously caustic and the fumes can be very dangerous to humans and pets). You could also use a spray from Toyota parts department made for this...
The max setting for the Air Conditioning utilizes internal air only, so think of where your feet are located (directly at the internal inlet port for the system), so if your feet smell like vinegar, etc. A solution is to spray disinfectant of choice directly into the upper dash vents with the system off and or to spray into the outside inlet ports at the bottom of the windshield with the system running and the outside airflow button selected.
Your vehicle may also have a charcoal filter for purifying the internal air, it may need to be changed, as well.

What causes a burning smell from the vents of the car when the ac is turned on?
Any smell from the car vents is unrelated to the AC system unless it is an antiseptic smell. Generally, the smells are environmental from your engine compartment, where the fresh air is taken from. If you smell something burning from the vents, then something is heating up to much under your hood. Check your compressor for a worn clutch, or oil leaking onto the exhaust manifold.
