/C system odors typically result from uncontrolled growth of bacteria and other microorganisms in the evaporator part. Nasty little beasts like aspergillus, cladesporium and penicillium grow on cooling coils and other areas. How do these beasts get there?
They are naturally present in outdoor air and are drawn into the system through the evaporator during system operation.

In a typical passenger car or pickup truck, the evaporator is usually located inside the passenger compartment, quite often deeply buried in or under the instrument panel.

The condenser is the other heat exchanger in a mobile A/C system. Nowadays, condensers are usually made of aluminum, but in the past, some were made of copper/brass. Condensers look very much like radiators, just a little thinner, and since they also depend on air flowing through them, are usually located in front of the radiator.
