Model 3 AC Smell Update...

Try also running the heater on full hot and high blower for about 10 minutes on non-recirculate. I notice the odor is at its worst with heat and after the cleaning procedure I ran first blower (no compressor) for 20 with all vents open on high (I used Klima) then heater for 10 to kill off and dry out anything. I was starting to get the smell back after about a month so I ran the heater at full/high again and when do with to recirculate and added a couple of puffs of Ozium into the right foot well so the system would pick it up. Kept the car closed. This morning no scent. I used to spray Ozium into the intake from the top but found that left residue on the intake area. When you remove the filters see if the condenser is wet. I noted that when I removed the filters and gently touched the condenser it was still wet. That is why after the process I now run no recirculate (if able for temperature) and weekly full heat.

I have done various forms of ozone (cans and generators) as well as sprays (Lysol, etc), and also have run high heat. It does work but doesn't last.

I get you point though. If I can't find a solution that will last a year then I will have to find some regular maintenance return as you suggest.

I have noticed there is a very bad smell if I turn off the AC for few mins - and turn it back on - there is a very foul smell like a rotten egg.
What is the solution?

So I changed the filters today and dropped one of the push clips that's under the dash. It seemed to go under the passenger seat, but when I reached under to grab it, it disappeared. So far I haven't been able to see where it ended up. Any ideas? I'm pretty sure it was under the passenger seat at some point.

Well I did it myself...and the screw fell into the car. Luckily no rattling..and there is no retrieving it for sure where it dropped. So I taped up that plastic cover.... So I'm ready again to replace the filters and do the can of Kool It... BUT does anyone know if I can replace that screw at HD or Lowes? Or get one that fits that does not use that crazy screwdriver head type?

By the way .. next Time I am getting THREAD and tying it to the screw so that if it does drop..I can retrieve it and then once its screwed in I can either ignore it and see if it breaks from contact or just cut off the extra after I'm done.
Try replacing with this from Amazon

I have found after foaming the condenser along with new filters to park the car in Non-Recirculate. The fan comes on a low setting a few minutes after parking to dry the condenser. I try to run with recirculate off while driving but if automatic needs recirculate I allow it but make sure I park with it off to allow outside air to dry the condenser.

That is an old post... I did some research back then and I do now have that screw in the car. I got the Tesla repair person to do it when I had it in for service.
