A/C related smell
Hi,
I just started noticing a rather minor inconvenience with my '98 Civic. Whenever I'm starting the car after previously turning it off with the A/C working, for the first few minutes the ventilated air has a tepid smell, regardless of whether the A/C works or not. The smell is hard to describe, it hints an old, rotten, steaming rag. This did not happen before or with my other, newer Civic. If previously the car was turned off without having the A/C operating, no smell comes out when I turned it back on. What's up with this? Does the A/C need some sort of servicing? Is this the way old A/C goes? Thank you. |

To reduce the smell, always turn the A/C and recirculate controls off well before you shut the engine off, to dry out the coils. Also make sure the condensate drain isn't blocked. |

It is nothing more than a plastic tube that runs from the drain pan to the underside of the car near the passenger's feet. Cleaning is done by running a cleaning rod of some sort up the tube or by blowing air through it. If the drain plugs up altogether it is common for the drain pan to overflow with condensed water and soak the carpet on the passenger side. This is a very common problem and not often easy to correct. The smell comes from mold trying to grow in the evaporator and drain pan. IIRC it was one of the regulars here that came up with a vodka procedure (no kidding!) to knock down the mold - maybe he will update me.

When the A/C runs and there is humidity in the air the drain tube will drip water (unless it is completely plugged). If you let the car idle a few minutes with the windows open and the A/C on you will see a puddle forming on the ground near the passenger door - that is dripping from the drain. You may want to spend the modest amount to have an A/C pro check it out. They can ensure the drain is clear and probably have a procedure that works well. Mike |

I had to do a web search myself to find it. ;-) Non-toxic A/C System Cleaner Mold, mildew and fungus growth in automotive A/C systems is a common problem, especially when the air intake control is regularly set to "recirculate" or "Max A/C". There are commercial cleaners available that can control the problem, but I have yet to locate one that isn't both moderately toxic and strong-smelling. Since I'm somewhat sensitive to noxious odors and to chemicals like ammonia, I have developed an easy to mix, non-toxic alternative that, for me at least, works as well as or better than the commercial products. In the interest of a less-toxic environment and as a public service, I am posting it. Materials Needed: Clean adjustable spray bottle, preferably 24oz or smaller. Cheap vodka Apple cider vinegar It is probably possible to use white wine vinegar, but I haven't tried it. Feel free to experiment, at your own risk. Mix the two ingredients in the bottle: three or four parts vodka to one part cider vinegar. Application: With the recirculate control set to "fresh", the ventilation fan on medium, all windows open ,and the engine and A/C running, spray generous amounts of the mixture into all of the outside air intakes. These intakes are usually located at the base of the windshield. If the system is already seriously moldy, wait a minute, set the air intake control to "recirculate" or "Max A/C", and spray the mixture into the air recirculate intake, usually located above the front passenger footwell, or sometimes behind the glovebox. Let the A/C and fan run for another minute or two, then switch off first the A/C, then the engine. The car will smell strongly of vinegar for an hour or two, but I find this to be both far preferable to the smell of the commercial cleaners and shorter-lived. Leave the windows open a little when finished, if possible. Like commercial cleaners, one application may not be enough, so I suggest weekly applications until the problem is gone, then preventative treatment once a month during warm weather. Precautions: This formula is non-toxic, but not completely harmless. Use common sense when applying it. That means not getting the spray in eyes, nose or open wounds, and not applying it with people or animals in the vehicle. Depending on the proportions (and again like some commercial products) the mixture may be flammable, so don't apply it while smoking or near any combustion source. As with the commercial cleaners, remove any residue from painted and/or plastic surfaces after application, as it may harm the finish. Finally, don't drive the vehicle until the vapor has dissipated; not only is there a slight potential for intoxication, there is also the possibility that this cleaner can produce a false positive on a police breath alcohol analyzer. |

The car will smell strongly of vinegar for an hour or two, but I find this to be both far preferable to the smell of the commercial cleaners and shorter-lived. Leave the windows open a little when finished, if possible. Like commercial cleaners, one application may not be enough, so I suggest weekly applications until the problem is gone, then preventative treatment once a month during warm weather. Precautions: This formula is non-toxic, but not completely harmless. Use common sense when applying it. That means not getting the spray in eyes, nose or open wounds, and not applying it with people or animals in the vehicle. Depending on the proportions (and again like some commercial products) the mixture may be flammable, so don't apply it while smoking or near any combustion source. As with the commercial cleaners, remove any residue from painted and/or plastic surfaces after application, as it may harm the finish. Finally, don't drive the vehicle until the vapor has dissipated; not only is there a slight potential for intoxication, there is also the possibility that this cleaner can produce a false positive on a police breath alcohol analyzer. |
