I have owned many, many cars and never had an AC stink, like this 2017 Pacifica. I took mine into the dealership after I had replaced my own cabin filter (no change in smell). They checked it out, aired it out, might have sprayed something in it, was OK for a short time and then it came back. I was always using the recirculating feature as it is really hot in our AZ summers. After reading the forum suggestions, I experimented with the Lysol trick and never using the recirculating feature. That lasts for a while. Yesterday I had the AC on high for a 20 minute ride, I left the car idle in my driveway and looked for a drain, puddle etc. but not a drop of water. I mentioned this to my dealership when I fist took it in 2 years ago. It hasn't left a drop... ever, and I run my AC 6 months a year. Perhaps they use the same concept as household appliances do. The condensate runs into a drain pan and the compressor cooling fan blows over the pan and evaporates the water, so likewise if you don't let your car blower/fan run for a period of time after the AC has been generating water, then the water doesn't get a chance to evaporate and then the mold starts to grow. My garage floor has never been wet in the 2 1/2 years I've owned it. Poor design is my guess and my solution is for Chrysler to issue a recall to install a proper drain line. Mold? Yikes, sounds like a health issue waiting to happen.
