I wonder if those of you who live in hotter climates (like AZ, or southern CA, TX, etc) can answer this.
I have to set up this question:
During hot days in summer (let's say around 95F outside temp or so).
Setting the AC temp at about 69F on auto.
When you get into the car in those conditions and have the temp inside set as such, does the AC remain on on full blast during the whole drive, or does it spin up to max at first, then as the interior cools, does the fan slow down to a mid/lower setting?
What I noticed in mine is that on hot days, if I set the temp like this, I can get into the car and the AC will blow at max the whole time pretty much. I thought I can attribute this to the sensor being on the right side topside of dashboard (and black in color), but I still think the AC should only be at max for a shorter while, and when the interior cools down, the fan should come down substantially just to maintain the temp.
Hope some of you can ring in on this. My suspicions are the AC needs a bit of charge to make it colder, but I don't want to do this unless it is necessary.
Thanks for input. |

It blows on MAX for a while then as the interior temp cools down, the fan speed dials down automatically. It does take quite a while to slow down though, esp if its 95F.
On a really hot day, I always open the windows for the first minute or so to "vent" the hot air inside the car, then close it and let the AC do its thing. |

I think Georgia is a valid "Hot" place.
It is as Eric says. |

I'd love to respond, but apparently all of our 90-95 degree days last month don't qualify. ;) |

In my opinion the MO's A/C is barely adequate for stop-and-go driving, but is satisfactory at highway speeds.
The CVT makes the VQ a relatively slow-revving engine. Because of this the A/C compressor is mostly operating at the low end of it's range.
My suggestion is to lower the windows until the interior temperature drops to match the ambient, then utilize D2 to increase revs around town, and dream about cooler days.
Stay cool....

Excellent. I was trying to make comparisons to see if by a chance my AC needed a recharge to make it cooler, but it looks like you guys are seeing the same thing. |

My MO is the same, I thought something was wrong with mine too because I rented a Maxima and it seemed to be doing a better job of cooling in stop and go traffic; however coming back to Atlanta yesterday on I-20 the AC had me totally chilled out, it was like an icebox.
I do notice on the MO that the compressor cycles on and off every now and then. I guess this keeps it from freezing up? |

Today we are pushing 100 degrees and this past weekend we were in the mid-90's . My AC operates as Eric says ... when on Auto after starting the car the AC kicks in full blast and after a few minutes (less than 5 - more like 3 to 4, literally) the fan begins to cycle down to slower and slower speeds as the car's interior cools.
Hope this helps. |

| I think in any car... baking in the sun to hope that the interior will hit 69° is wishful thinking. Try setting it to something like 72-74° the fan will come down as the temps are more sustainable. |

Tried that and it did start throttling down after a few minutes at setting of 72F.
Putting it to 70F makes it go full with closed air (recirculation) all the time (with ext temp at around 92F). |

Got to agree with EricL and Gonzo.
Temp here has been hovering around 100 last couple of days. Officially, 98-98, but the MO says 102 out on the highway (during 20 minutes over 60) and 98 in the garage.
I keep the driver's side on 72. Boss Lady keeps the passenger side on 68.
I, too, "vent out" the hot air for a few seconds. The AC settles down after a couple of minutes and has no problems on the highway or in stop and go. |

| Did that too. Seems to work easier if I set it to 72 after a quick vent with windows. Then, it will slow down after a few mins. Looks all ok to me, with all your comments. Thanks again. |
