How to fix it

 

The drain is clogged.

 

X2. The AC evaporator box drain is clogged.
Simply unclog it at the firewall with a short piece of weed eater string. If you don’t know how or where the drain is, then take it to a repair shop.

 

It’s just to the passenger side on the fire wall


That rubber tube , just insert a piece of weed wacker plastic line, wiggle it about and watch the crud and water drain out.

 

I bet the AC air stinks. The big box auto parts stores sell an aerosol product you spray into the vent it foams up and kills all of the nasties that stink and clog the drain.
Probably change the cabin air filter, it is probably from the factory since nobody reads the Owner Manual (link in my sig).

 

Don you forgot rule #4 if it doesn't work get a bigger hammer
