I wasn't asking about maintenance. You made a statement about some cause and effect without providing any basis for the connection. This is what I asked you to do. BTW, it isn't necessary to be religious to use the style of religion - making statements lacking in substance or reason. >> [1] Anecdote time - >> >> My previous car had done 10k in it's first 6 months and it was kicking >> around forecourts for another 6 months before I bought it.

[Smell] "has nothing to do with mileage, or the length of journeys, and everything to do with the amount of time the vehicle is left unused between journeys". Yes, they had/have A/C and according to your original statement I have given you all the information you require. Now you're asking for all sorts of conditions. So, we find your statement is hopelessly incomplete. At least, now we know what's missing it's possible to work out what kind of (very limited) circumstances you were thinking of.

I didn't directly make a statement. You asked another poster (Pete M) to explain why running the A/C regularly would help prevent the smell. Perhaps sensibly, he didn't answer, so I sought to enlighten you. The cause: allowing water to condense on the A/C evaporator. The effect: bacterial growth making the A/C smell. The basis for the connection: common sense, personal experience, plus the experience of others reported here and elsewhere. If that's not "scientific" enough for you, I repeat< you're asking in the wrong place. > BTW, it isn't necessary to be religious to use the style of religion - > making statements lacking in substance or reason. The statement I have made regarding the likely cause of smelly A/C is not lacking in substance - it exists. In what way is it lacking in reason? You've challenged my statement as lacking in scientific proof; this isn't a science NG, and I'm not a scientist. Within those parameters, I consider what I said, (as supported by many others in the past) to be completely reasonable. > >>> [1] Anecdote time - >>> >>> My previous car had done 10k in it's first 6 months and it was kicking >>> around forecourts for another 6 months before I bought it.

As I'm not your mythical scientist, when I made my "original statement" I quite reasonably made the assumptions that any sensible person would when trying to explain to you what may cause A/C smells. (Boy, do I wish I hadn't tried to be so helpful!). > So, we find your statement is hopelessly incomplete. At least, now we > know what's missing it's possible to work out what kind of (very > limited) circumstances you were thinking of. <Looks left; looks right> No, there's only you and me here; where are the mythical "we"? My answer to your question would be complete enough for any normal person to understand in the context in which it was asked. So the circumstance in which a car is used for short trips with the A/C on, and then left for longer periods without use, is a "very limited circumstance"? I don't think so; it's certainly how my car is currently used, and I think my usage pattern is increasingly common. Chris -- Remove prejudice to reply.

Basically, I was going through this NG and I responded to stuff already written. I was not asking for advice - I asked for more background to advice (though it was couched more as an instruction than advice) already given. You mean, "maintenance" is supposed to be solely about how to draw air through the teeth and doing a spanner job? >> You made a statement about some cause >> and effect without providing any basis for the connection.

Instead you gave yet another soundbite which you can't back up. Neither of you have added the slightest thing towards helping to control aircon smells.

There you managed to provide an answer to the question. You could have stopped there but you then went on to give a reasonable explanation for your opinion. Pity it's been such a struggle in this neck of the woods.

As ever, things need to be considered in context. One could probably find a dozen different definitions of "maintenance". However, in the context of this NG, it's contained within the NG charter, which makes no mention of the expectation of a scientific explanation. >>> You made a statement about some cause and effect without providing any >>> basis for the connection. This is what I asked you to do. >> >> I didn't directly make a statement. You asked another poster (Pete M) >> to explain why running the A/C regularly would help prevent the smell. >> Perhaps sensibly, he didn't answer, > > Or perhaps he just offered a soundbite and has no background.. I really think that you don't properly understand usenet. You seem to be regarding others here as some sort of paid expert service. Often, if one has a problem that can't be solved, a "soundbite" (a horrible phrase BTW), might be all that's needed to send you in a different track. I have a fair bit of free time; I choose to spend some of it on usenet, and some on web forums, trying to help others. Sometimes, I am able to help directly, Sometimes, I can only comment. In both cases, I try to help. What are you contributing here? >> so I sought to enlighten you. > > ...which didn't even touch on PeteM's claim.

Which, incidentally, has nothing to do with the thread title, and is so OT it would have been squashed on any moderated group. Right at the beginning, I said: "In even moderately humid conditions, water will condense on the evaporator. (That's why you see puddles under cars with A/C.) If the system is only used infrequently, for short periods of time, the condensed water doesn't dry out and encourages bacterial growth on the outside of the evaporator. This is what smells. It actually makes perfect sense, and IME, does happen." and: "The reason being that it gives the evaporator a chance to dry out before you switch off." If you think that had not added the slightest thing towards the problem, that's up to you. It's certainly added more to helping understand a solution than any single thing you have contributed...
