Replying to: ceric (Sep 11, 2008 8:57 am) As far as 3rd row cooling, I have found (actually my kids) that the 3rd row is adequately cooled at outside temps up to 115. We regularly visit the CA/AZ border and I have yet to hear one of mine complain that it's too hot in the back.

Replying to: maltb (Sep 11, 2008 9:35 am) Note that the air ducks below 2nd row seats stop functioning when the air flow is only directed to the upper torso. That might be how you jump to that conclusion.

Replying to: ceric (Sep 12, 2008 9:45 am) Perhaps I should have prefaced that with: when in AUTO mode. Now that we have that out of the way, let's discuss how effective floor vents are for the perceived cooling of a vehicle. Next time it's 90 degrees outside, manually run your A/C through your floor vents only and let me know how long you last in the vehicle. Cooling through floor vents is plain useless unless you have severe foot sweat (in which case I'd recommend seeing a good doctor). There's a reason the auto mode doesn't route cooling through floor vents.

Replying to: maltb (Sep 12, 2008 12:54 pm) Again, I have to tested it myself to believe that the floor vents is completely blocked out from cold air. Right now, I have a hard time believing it.

Replying to: ceric (Sep 12, 2008 5:20 pm) After some testing, I believe you were right. I stand corrected. In AUTO mode, cold air flows thru the upper vent, hot air flows thru the floor vent (which makes sense). For cool air to come out of the floor vents under 2nd row seats, one has to choose the venting mode manually, not AUTO mode. |

I have a 2008 GT AWD with 13K+ miles. I live in central Ohio and lately because I have not needed A/C I have turned off the A/C, which also appears to turn off (at least the light goes out) the "Auto" mode. However, I have noticed, with the exception of introducing A/C, that the "Auto" mode still appears to work with respect to introducing heat, satisfying temp settings, and controlling where air flow comes out. One phenomena that I have noticed is that after initial startup and within the first two to three miles, the HVAC system momentarily (one second or less) shuts down (fan speed goes to zero), and then returns immediately and continues to operate properly the remaining time you have it on. Has anyone else noticed this phenomena? As long as it always turns right back on, I probably will not do anything about it. However, it is strange.

Replying to: skc7 (Oct 28, 2008 4:59 am) Recently I have been testing how much MPG I could save by turning off A/C (since the weather is pretty cool, I opened the moonroof). My A/C has been completely silent. I don't recall A/C actions at all. You might want to go to the dealer and have it checked out. BTW, my experiment showed that you can easily save 1-2mpg with A/C off.....

Is anyone having an issue with the rear air controller in the 07 touring? If the rear air controller is off, then the rear air is uncontrollable. It blows out at full speed and the front fan control speed does not change the rear fan speed at all. If I adjust the temperature control knob, the rear air fan speed goes higher and lower accordingly. Is this right? Should I have to keep the rear air switch engaged full time to keep the rear air off all the time? Shouldn't the option be, rear air switch off=front controls work all of the air, rear air switch on=rear controls work rear air and front do not. Does this make sense?

I have another issue with the a/c in my 07 touring. Intermittently, the front fan will turn on full blast after the car is turned off. Sometimes keys are out of ignition and in my hand when this happens. I don't have the keyless start option. My dealer says that since this is intermittent they can't fix it until they see it happen. I have seen other posts about this, but would like to know if anyone has had this repaired and what exactly was done to repair it? Thanks!
