Those are overall great tips from spots, I would add, 1) Park in the shade so the car is not an oven to begin with, and 2) Crack all of your windows a 1/4 inch when parked, which gives a path for hot air to escape. I regularly use my sun shade, it makes a huge difference, plus its nice to not have to try to drive a car who''s steering wheel is a hot potato.

A related thought, I suggest taking it off recirc mode after you are cooled. 21st century cars are quite well sealed, if you have all the windows up and have it on recirc, there is not much fresh air coming into the vehicle. It can be legitimately very dangerous if you are a smoker (or in a car with a smoker), as a burning cigarette (or burning anything) is a big user of oxygen.

One thing I noticed also, If you put your temp on the coldest level and run it on foot and defogger (which won''t allow you to turn the AC on) it will keep you cool similar to the AC without taxing the engine......just make sure to kick the fan up to 4 for max air

Won''t allow you to turn the AC on?

The only setting which absolutely prevents the AC from coming on is if the fan is set to zero (ie. the system is shut off).

That was/is my impression/experience too?
What system do you have in yours... auto climate or std?

BTW, When the Defrost is on th AC compressor is on, and if you have it set to all the way down the heat is not mixed in.

I too drive at freeway speeds and my AC works fine at a blistering temp of 116 in AZ. I did notice it struggles in city driving.

I have the Std. AC on my i-touring and whenever the Defogger and feet setting is set you can''t turn the AC light on.....but the Air comes out really cold

The A/C is certainly on then, even though the indicator does not always show.

My ''04 doesn''t work that way though. If I hit the switch the indicator lights no matter where the dial is set.
Anything to the right of about the 11:30 position (just to the left of the footwell only position) automatically calls for the A/C to be on in these, and many other modern cars/trucks, though the indicator may not light.
My A/C still comes on, though the indicator does not light if I haven''t already hit the A/C switch, but will stay lit if I have.

Check your owners manual for further details. Perhaps there was some kind-of-a change for the ''08.5''s?

You DID read your manual, didn''t you?

It took me an entire night when I first bought mine (70+ pages,) but I read it.
The one for my MIL''s ''02 Cavalier was even longer, and for a car that''s not half of what ours are too.

I think its highly likely V1 is correct. I have not heard of any car built in the last several model years that does not automatically kick the AC comp on when you switch the front defogg on. According to my manual, for the 07, the AC certainly does come on when using front defog. You might want to give your manual a read. The fact the air comes out really cold is an indication the comp is on - what else would explain the really cold air?

I''ve also heard that the air cond. is only supposed to be 10 degrees colder than the outside ambient temperature.
