Glad to hear the A/C is ok for most drivers, will wait till the temps and humidity here gets a lot higher to check it out..

2007 Limited AC vs Fresh Air Mode by tallyclassic

I've had my SF Limited for 2 weeks now and am confused by how the 2-zone AC controls switch back and forth.
I've read the manual several times and it should be as simple as turning off the Auto AC button. Then the air coming out the vents should be fresh air.
Well, actually if you are in AC mode and you turn it off, everything is off, even the fan. Then I touch the fan speed button, the fan comes on but AC (cold air)comes out the vents. I also hear the compressor cycle.
I've gotten the system to work right just once. The screen showed the two temperatures that moved simultaneously, which vents were being used, and the fan speed. Then it got warmer outside and AC was needed, and switched over to Auto. A little later in the same ride is when I realized I couldn't go back to just outside air.
 
Anyone else have this kind of difficulty??

I've had similar problems trying to figure out the different configurations. I can see how the mode button works to operate the face vents,floor vents,defog windshield - I think with dual control ("Auto" off) you have to have the A/C button on as well, then set the temps. for each side.
 
I've turned Auto off and the fans blow but no A/C seems to be on, unless I push the A/C button in and it lights up. Everything stops(fans, A/C) if I push "Off".
 
I also noticed that the fan speeds are much higher with "auto" setting with the recirc. on than regular dual or A/C mode. It must have a booster for the fan in "Auto" recirc. mode.
 
I posted elsewhere asking if anyone else experienced a lag of about 8 seconds or so, when first starting up with the Auto Climate control on. I noticed it doesn't start blowing immediately, even though the engine is running - does yours do that too?.

My problem with this system is that if it's about 60 degrees out, and I don't want anything on, their is still a cool breeze coming out of the vents. I realize this is the fan blowing the cool fresh air, but it's too cold. If I push the "off" button, nothing happens. The fan still runs. I also looked in the manual and could find nothing that would help me.

It's actually pretty simple. by mpuzach

I can't tell from your post exactly what you're trying to do. Here are a few tips:
 
  • When you select "Auto", the system will automatically control temperature (whether heating or cooling is needed), fan speed, fresh air intake vs. recirculation, and choice of output vents.

  •  
  • If you just want fresh air (without A/C), turn off the A/C button and manually select a fan speed and choice of vents (using "Mode" buttons).

  •  
  • If you want A/C but want to choose your own fan speed and/or output vents, just make sure the A/C button is on and manually adjust the fan "<" and ">" buttons and "Mode" buttons to your liking.

  •  
    That's pretty much it. If the system is in the "Auto" mode, it will come out of "Auto" the moment you adjust fan speed or mode or the moment you turn off A/C.

    What if you just turn up the temperature setting?

    Hi,
     
    I've been a long-time reader of this forum....very helpful!!
    This is my first post.
     
    I concur that the A/C system is pretty simple & agree with your summary. What bothers me, in AUTO mode only, is that (at least on my '07) the A/C button never lights up, even when I know that the A/C is running. The button will light up when I take the system out of AUTO.
     
    Is this how it is designed or do I have a problem?

    I just checked mine and it works the same way yours does. I suppose in a way it makes sense since under certain conditions (e.g. when it's cold outside) the unit will be heating rather than cooling when in the AUTO mode. Regardless, it looks like they're functioning normally.
