Hey!

So I'm sure we've all noticed how setting the environmental control to windshield defog (is that the right term?) automatically turns on the AC as well. At least on 5th Gens it does. As we know, this is so that the air blowing on the windshield will be de-humidified to assist in defogging the windshield. Anyway, my question is, what's the coldest outside temperature that keeping the AC on has any effect? Here in Winnipeg it gets fairly cold, so keeping the AC on at -30C seems like a bit of a waste. I can't see the AC getting the air even colder then -30C, nor can I see it removing any moisture from the air at that temp. Granted, at -30C, there isn't that much moisture, but how about -5C? At that temp there usually is a lot of humidity in the air so I often keep the AC on just in case. However I do wonder if the AC is indeed removing any moisture at -5C, or am I just wasting gas?

Also, can running the AC in -35C weather damage the AC system?

Any thoughts?

Your heater warms the air so that it can actually work anytime. Any Honda I ever had during winter months had its AC left on full time to offset melted snow.

Hmmm.... Doesn't it go through the AC before it goes through the heater core? Perhaps I've got it all back wards. If so, then I guess that explains how it works. But that leads me to my next question... Where does all that condensed moisture go? Normally in the summer it just flows down onto the pavement, but in winter it would freeze up. Could this explain why I often notice a musky sent when the AC engages?
