These tend to grow, reproduce and live around your evaporator core. When your blower starts up it blows air across the evaporator surface and collects this smell sending into your cab via the vents.

Dirty Cabin Filters

Many air conditioners recycle the air inside your vehicle through the air conditioning system as an energy saving measure. As the air is sucked into the air intake any smell introduced into the vehicle such as cigarette smoke, children of pet accident smells, foods and other sources can become trapped in filters and then compound over time. When you turn on the a/c these smell can then be redistributed around the cabin

Dirty Primary Air Filters

It is important to regularly clean your primary air conditioner filters as they can collect dirt, dust and dust mites as well as stagnant water and other airborne pollutants. The resulting bad smell will reoccur every time you turn on your a/c unless you replace or clean the filters regularly.
