Stinky A/C what to do?
Hello!
I have a 2010 LS460, It does not have the additional A/C controls in the back seat. My A/C on start up and initial running smells kind of stale, molding, stinky. I did just check the cabin filter and it does not smell and is not that dirty. I keep my car pretty clean... maybe too clean as I take it through the auto car wash twice a week, at least, whenever it looks dusty/dirty. The interior is spotless. Nothing old, no musty cheese anywhere, I don't eat in the car so there is not an old jumbo jack with extra mayo hiding out under the seat.
I feel like maybe some leaves got into the ventilation system, or there is excess water from the washes somehow building up and getting stinky... I do have to park the car outside near a tree and some bamboo, so in the morning there is often leaves on my car.
Not sure where to start and how to remedy? Could someone let me know what the next steps should be?
Thanks,
Rodney

Likely there is/was moisture build up on evaporator which in turn causes build up of bacteria and thus an odor.
Remove cabin filter, run heater on HIGH for 1hr, A/C OFF, recirc ON, (this dries the evaporator/case out) then run an ozone generator(you will not want to be in the car until the ozone smell is gone. then install new cabin filter(preferably charcoal filter)

OP, make sure the carpet under the passenger side of the dash is not damp. If it is the above is very likely your issue.

I just like you, have a pristine cabin filter, do not eat, fart or anything in my car. It's immaculate, always.
Lot of quick fixes, one of them being this.
1. put your car with the AC on, on high (fan direction towards center -> only) . RECIRC mode OFF.
2. roll all windows fully down
3. pop hood
4. take Lysol (or any spray with mildew/mold killer and spray into the vents you see near the wiper blades, there should be two series of vents, one near center and one near driver side.
5. spray into the vents for about 30 seconds straight. each series of vents.
6. while leaving AC on, crank the temp from coldest to hottest and repeat the steps 4 and 5.
7. let the air run for at least a couple of minutes after spraying with windows down.
8. roll up windows and close up car, i recommend leaving a 1cm crack in the windows to let fully air out.
-- optional, i throw in an ionizer and packet of japanese charcoal bamboo ---
8a, sprinkle baking soda on the floor mats and carpet as a whole.
8b. let it sit for about ten minutes
8c. vacuum it up.
works like a charm for me anyways.

Check your car for mice too!....... These pests get into the car and pizz everywhere.
Ozone generators work great for eliminating smells but unless you get rid of the source they come back.

RE: Ozone generators
How long did you run it?
Where in the vehicle did you place it and with the ozone flow towards front or rear?
My problem arose after roof drains clogged, causing soaked front seats, causing... etc. I have already done a thorough visual inspection, removed visible mold [under front passenger seat], sprayed Concrobium, Lysol, and used a mold-kit that supposedly gassed the car. Also changed cabin filter. Still smells bad.
Thanks for your help.
