With the blower on full and in fresh air mode spray lysol into the air intake below wipers until you smell it in the car…that will kill whatever mold is causing the smell…

The drain hose is on the firewall, low on the passenger side. You may have to raise the car to reach it.

DO NOT crawl under a car supported only by a jack. Use jack stands or ramps.

In addition, when you park the car, leave it with the AC system in any position except off and recirculate/max. That allows a little air to circulate in the system.
