Could try something like this...

Since you’re spending money, may as well get an endoscope so you can poke around in there and verify things are clean.

I was also thinking about this. Maybe there’s something else in the engine bay that stinks and is coming in through the vent It seems like you’ve cleaned just about everything else.

 

Does anywhere else you go smell consistently of farts? Have you been in any fart smelling elevators recently? I might have some bad news man.

 

Im guessing you probably have to pull your dash apart. Here's the thing. Your evap core gets very cold, most likely cold enough to get a bit frosty. water and metal don't really go well together, especially when you have your system set to recirc. When you shut your A/C off, your evap core has no way to dry out because you have your system set to recirc, therefore moisture just sits on the metal and starts to grow funk. If you don't give it a chance to dry out, it keeps growing funk. Chances are this is why you have the odor, and if you just don't fix it the right way the first time, you are going to make yourself do twice the work down the road when you figure out that you have no choice but to clean the evap core. With all that being said, I am not a fortune teller and I may be completely wrong about why you have this smell. Just trying to save you some headache in case that's what it ends up being. It seems like you have tried everything else, and I don't really think pumping more chemicals into your vents is going to give you the results you are really looking for.
