Then why doesn't the defroster in my, or my daughter's Corolla, my wife's MPV, or my other daughter's Cube (all of which are equipped with A/C BTW), or any other vehicle I've owned my entire lifetime for that matter, clear the windows until the defroster starts blowing warm air? I suppose you're going to say there must have been something wrong with each and every one of the defrosters in those vehicles? I realize vehicles equipped with AC dry the air when set to defrost, but that doesn't mean they will clear/keep the windows clear when there's no heat coming from the vents...
Then clearly, there IS something wrong with them...either a problem with that vehicle, or a poorly-designed HVAC system. The only vehicle I owned that WOULDN'T clear the fog off the windshield immediately was my old Jeep pickup...with no A/C and a heating system that was, at best, only fair. (It was a 1983, but basically an early-60's design.) Everything else, from my wife's Metro to my Cadillac to her Grand National to my Cherokee to the Freightliner M2 I drive at work...turn on the defroster, the windows will clear. It takes a bit longer cold, but still works.
LMAO! I guess no one here knows much about HVAC? So thermistors, pressure switches, pcm(BC) and temperature sensors play no part in air conditioning? So liquid coolant which absorbs heat and converts to gas, which is then drawn out, cooled and pressurized to be released again works at all temperatures??? well that's fantastic, where do I get one of those? The systems generally work in conjunction with one another, plus there is this whole physics thing with hot and cold air and absorption/saturation rates. Anyways that's besides the point...
I drive a Diesel, if it's plugged in I don't bother to let it idle. If I'm unable to plug it in, I always give it 5-10 minutes.
Yes, I would also like to know where these people are buying their vehicles with these magical HVAC systems that totally defy physics...
