    Hi Clarity drivers: Have you had issue with vinegar, old sock-like foul odor from your air conditioner? How do I get rid of it?

    I've smelled exhaust from mine sometimes, but so far every time that's happened I've had it on "auto" and it had switched to outside air instead of running the A/C or heat. Make sure it isn't on "auto" (the driver's side temperature dial should not have a green light) if you want to keep it recirculating the inside air and avoid foul odors from outside.

    Various "smells" likely to occur when using the heater sadly since it is not a conventional heater...that being said if there is any sort of coolant leak or if someone spilled something under the hood you may be smelling that :(.

    There is a service bulletin for a fix to the climate control 3 way valve so if you smell moisture I would take it into the dealer asap and see if that applies to your vehicle.

    thanks; mine only smells when using AC (cold) not when running heater.. outside air or recirculate didn't matter. I will call the dealer an see if my car is applicable!

    Air Conditioner units remove moisture from the air and should drain it through a small tube onto the ground. Maybe yours is not draining properly which can give you a sour smell when you first turn it on.

    I will drive home with AC blasting and then look for a puddle of water after parking!

    Do you live in a humid part of the country? If you run your A/C and stop the car w/o allowing the cooling grill to dry out, mold grows on it and that causes the odor, which gets worse with heating. To avoid that, always turn off the A/C while leaving the fan on for a couple of minutes before you turn off the car and/or fan.

    i am in SoCal, so I wouldn't consider it too humid? I have not run fans with ac off (which requires going into touchscreen), so I will try that... also, does anyone know if "Auto AC" is smart enough to keep foul smell away?

    You should NOT be smelling your own exhaust for any reason. If you are, then you probably have an exhaust leak and need to get it looked at sooner rather than later. Use the recirculate setting until you get it resolved. If it's just short duration random exhaust smells from other vehicles, that's fairly normal.

    As for the AC smell issue, the Clarity may be different, but turning the AC off is one of the easiest ways for mold and mildew to grow on the coil. I learned this the hard way. Smelly socks one spring after I turn the AC off during winter. I pulled the cabin filter, turn the air on high, and sprayed a disinfectant into the fresh air intake. A couple treatments killed the smell for me. Now I leave our cars in AUTO mode year round and have yet to see a reoccurrence.

    Thanks, watching youtube videos on disinfecting ac system!

    I think there is a cabin filter. check that too.
    I used to do this in my bmw.
    Turn AC on and blast fan to high. Open all windows. Make sure no one is in the car. Spray lysol into the cabin air intake , which should be near the base of the wiper arm. then let it run for awhile.

    My wife used to complain about the musty odor in our previous car. When I got my Clarity, it had the same musty odor from the beginning. It usually happens when turning on the AC initially. I heard some people say that you should run the car with the AC off before reaching your destination for the last 10-15 minutes to get rid of the moisture. I think that is too much trouble and uncomfortable.

    this morning I drove with "Auto AC" mode set at 70 deg (outside was 50) and it didn't smell. I think I will try leaving it at Auto and see if this will work when outside is hot. I see people try: 1) spray lysol-type aerosol disinfectant into cabin air intake from outside, 2) "bomb" type aerosol inside sealed car with recirculation, 3) alcohol-based foam injected into condenser via tubing into the vents. There seem to be a minority of people having big issues (damages from lysol, leaked alcohol) from these treatments.

    If you have an issue that will not go away, then try #1 from your list but remove the cabin air filter first and replace with a new one when you're confident the smell is gone. As for auto mode, I'd just leave it in auto year round. It worked fine in my cars except the one time I thought turning off the AC in winter would save me some money (fuel). Altima Hybrid is 10 years old and only had the issue the one time I took it off auto for a few months.

    Yes, I had this experience with an unpleasant smell from my air conditioner. And I couldn't figure out what was going on and why my car smelled like a dead rat.

    Always a good idea to run the A/C at least once a month, even in winter. Helps to keep things dried out. Noticed mine had a funky smell when I ran it the other day.

    I agree with your idea.
    As for me, when I finally discovered that this smell was coming from my air conditioner, I was both happy and upset at the same time.
    I was glad because I finally found the cause of the terrible smell in the room, because I thought that it was time to make big repairs. And I was really upset because it was very hot and without air conditioning it is impossible to tolerate this heat. And so, I had to contact the air conditioning repair servicing to get them to fix this problem. (The mechanic couldn't do it). I am grateful to them for their quick work and for not leaving me without air conditioning to die from the heat.
