Before you start using a bunch of expensive chemicals let me toss out a couple of 'seasoned driver' (what my insurance company calls us old guys) tricks.
1. With your engine up to operating temperature put your heater temp and fan on high. Run it that way at least 15 minutes. The heated air will help dry out collected moisture in the duct system where mold may have started growing. If that helps a bunch but there's still a little odor do it again.
2. Remove your cabin air filter and with the fan on low squirt some Lysol into the filter opening. The fan will circulate the Lysol around the vent system which will kill any mold growing in there. The odor won't stick around nearly as long as some other products (Febreeze will be with you seemingly forever).
3. Make sure your drain isn't plugged. When you run the AC you should see water dripping from a hose mounted low on the firewall. If there's no puddle under your car when you park (and the AC has been running awhile) the drain is probably clogged. Eventually moisture could build up to the point where it starts draining 'into' your car. 'Then' you're going to have a stink fer sure.
If you can remember to do it you'll eliminate this problem by turning off your AC a few minutes before turning off your car for the day. Letting the fan continue to blow will help dry out the system.
Cheers
