Hello all...

Got a couple quick question regarding the temperature control. Why is it that everytime I switch over to manual temp. mode and once you get to the defog option, the AC unit turns on? That is so annoying. It's freezing cold here in NY and the last thing I need to do is keep shutting off the AC when I make any changes. Also, how can you set it to CIRCULATE INSIDE AIR without turning it OFF first? I mean, alot of times if there's a car in front of me burning black smoke or whatever, on my other cars I would quickly switch to circulate inside air so I don't need to suck in that crap. I would always do that if I pass by some garbage truck. On my G...it's a pain. I would have to switch to OFF and to circulate inside button and once I pass the truck then I have to switch it back to manual and all that. Do you guys have this problem?

 

well the a/c is because if its not at cold inside the car as it is out side makes what we call condensation, like on a cold soda in the summer. ya know. and when is cold liquid freezes condensation is liquid. right so its gonna freeze so if you even out the temp it wont get condensation on it. andthe defrost isnt ment to melt ice its made to defrost get it.?

 

The idea is not to equalize temperature but to dry the incoming air.

The purpose of the A/C coming on is that the heat exchanger (coil) unit that the air passes though cools the air to the point where moisture condenses out, effectively drying the air that is being blown onto the inside of the windshield. The dry air quickly absorbs (or vaporizes) the moisture that has condensed on the windshield glass.

Without the A/C unit on it would take much longer to clear the windows, specially if it is raining outside.

 

Yes, I totally understand that A/C speeds up the defog issue. But the problem is I like cycling the mode where sometimes I want air to heat up my feet, sometimes my upper body, etc. Each time I cycle the modes when it gets to defog (but I don't need to defog), it turns the AC on. If I started doing something else then I'll realize after 10 mins later my AC was on. It's unnecessary and AC not only robs the car's power, also gas as well. Which is why I said it was annoying to begin with. If I want AC I can push that button myself.

You have any idea with that "circulate inside" button that I had the question on? Thanks!

 

I know I'm not really contributing to the thread, but I've found that a/c usage has no effect on gas consumption at all in this car. Also when you're gunning it the A/C compressor turns off so that you get maximum pulling power.

It does take some getting used to but in all honesty I stopped worrying and just started letting the climate control do it all for me, and I'm a happier person for it. Running the A/C when the weather is cold is just fine, and I've found if you let it do it's thing, you're MUCH less likely to wind up with a smelly AC which seems to be so common in the springtime.

 

Yeah, I don't know why it seem so confusing at first (I was the same, especially with the AC deal). Anyhow, the recirculate button is the button with the arrow circling IN the car, the outside air is the button with the arrow coming in. For my car I can switch back and forth on the fly. Do it everytime I get a drive in car wash (touch free of course).


I just googled the image, so ignore the circles drawn on it.

 

I don't have the premium package so I don't have some of the buttons like you. But my "circulate inside button" cannot be done on the fly. I have to hit the OFF button first before I can hit the "circulate inside button". Then once I hit the fan button it AUTOMATICALLY changes it to "circulate outside button". Meaning, I can't have air blowing w/circulate inside button pushed. Go figure. Any other G's out there with my same situation? Or is mines defective?

 

Hmm...interesting that when you gun it, that it turns the ac off. Regardless, I wouldn't want the AC running. It's more stress on engine no matter how you look at it. In NY, the past week was hitting -5 degrees (much better this week in the 30s) and I definitely don't want to see my AC on with that kinda temperature.
