sounds like we have some mechanical engineers in the house

 

Mine works just fine. Don't really use it that much but when I do it works.

 

No it's not pointless. For instance on hot days you HAVE to leave the a/c on to keep the car cool, other wise the secong you turn it off it get all humid and the temp goes to warm within a minute, so i can leave my side on 60 and my gf who cant handle the cold air can have it at 75, cool but not freezing. It works great, the the accualy temp inside the car never really gets "cool" when its 90+ outside and all the panels are hot!

 

i could care less if it works or not, "my side" works great

 

Mine too
And my wife seems to be happy w/ her side, so I think it's working flawlessly

 

Thanks for all of the responses. I have read quite a few differing opinions. Perhaps the dual climate control “works” but does not meet my expectations when compared to a 2002 GMC Envoy, a 2005 Lexus LS 430, or a 2007 Yukon Denali—all featuring dual climate control and all working noticeably better.

If the goal is to reach a steady state temperature inside the car, I understand that introducing air at two different temperatures is not efficient. However, I believe the purpose of the dual climate control, as some of you have noted, is to allow each person to “feel” air of the desired temperature, with the understanding that the actual ambient temperature inside the car will be some intermediate temperature.

I always leave the fan on auto, under the assumption that the fan speed will be automatically adjusted as needed.

As for the 7 degree difference, I am not finding that my HVAC system follows that rule. Even with a 10-15 degree difference in set temperatures, the system seems, for lack of a better word, indifferent.

In an attempt to remove the subjectivity of a relatively minor variation in temperatures, can anyone tell me what happens when they set the driver temperature to the maximum and the passenger temperature to the minimum? Maybe this will provide insight into the correct functioning of my “dual” climate control.

Thanks.

 

you are spot on.
those that say the dual climate control in the G is "flawless" or "working perfectly"
have not had the privelage you and I have had to sit in cars where it
actually works as it is supposed to.

I wouldn't have taken mine back to the dealer if I thought it was "fine"
or "working properly."
The salesman literally sat in 5 different G's with me on the lot and in the
showroom to prove both of our points.

1. the way my car is, is standard, normal and the way Infiniti makes it.
neededing a bare minium of 7 degrees for the air temperature to even change
coming out of the vents. a 20 degree difference is needed to see any sort
of drastic change (5 degrees) in outcoming air temp.

2. the system is obviously inferior to many others on the market.

after sitting in all the G's, I had the salesman and the mechanic, one at a time
sit in my 2008 Acura and watch what happened when I changed the difference
between the driver and passanger settings just buy one, two or three degrees.

the air temperature immediately changed and responded, unlike the Infiniti.


at the same time we addressed the very poor sunroof seal that will leak any
time the G goes through an auto car wash.
at first the sales guy didn't believe me, so I took him through one.
and sure enough it leaked like a siv under the pressure washing.

I followed that immediately with my Acura, and not one drop got through.

He then took a G from the lot through the wash, and it leaked too.

So that is just another standard measure of poor quality in the system.

It is just the way it is. Not all things work right on all cars.
These are two clear problems or deficiencies the G has (I have a 2008 G).

 

My dual-zone climate control accomplishes exactly what I need it to, so I'm happy.

 

I'm happy with it as well. I'm always warm in the car and the wife is always cold. I set my side at a lower temp. The cool air that shoots out at me keeps me comfortable and at the same time, she doesn't feel it. She just feels her side staying warm and comfortable.

I will say this though.... My 99 Jeep Grand Cherokee had dual zone climate. That system had little infrared sensors for each front passenger and would self adjust itself if it sensed you getting warmer or cooler. Kind of a neat system. The bad part about the system was that it only supported a 5 degree difference between driver and passenger settings. kinda stupid.

No complaints with the G though.

 

I agree the dual climate is pretty much the suck.

The wife likes it warmer than I do. I might have mine set on 68 and it's blowing nice and then she'll hit hers and turn it up and the fan slows down on mine. I'm pretty sure there is just one blower and changing the temps on one side ends up changing the fan speed for the other. While the temps may remain somewhat proper, the fan speeds changing sucks.

 

actually I did, that's why I'm driving an Infiniti now!

 

Works perfectly fine for me. I always have it down at 60-70 while the wife cranks her side up to 90, I'm comfortable, but her side is HOT.

 

Mine works fine also...I guess it has to be extreme to notice though.

 

I don't have much of a comparison, but I think dual climate control has one basic goal.

Make the air that is blowing directly on you either warmer or colder than what the car is set too. In my world its even simpler, make the air in the passenger seat warmer for my wife.

Mission accomplished. Works like a charm and if that's 7 degrees, so be it. I just went out a did a very simple test. Somewhat cold morning, let the car warm up a little bit. Set car temp fairly cold and slowly increase the passenger seat temp. Worked without issue (even less than 7 degrees), but I did not involve the A/C so that may not work as well, who knows.

Asked the wife if it works and her response was...'weird look'....um....yes...why you ask that? I conclude from that, that it hits its goal of functionality. Acura functionality really doesn't mean much to me even if its better. I could have purchased an Acura, but it lost out in other areas. In fact, dual climate control capabilities wasn't even on my list.

 

Just had my car in for service and I mentioned that the heat doesn't seem to kick in until I put it up to 76. They said that the "ambient switch" must be set to summer. Whatever, but when I got the car back the heat starts to kick in at 62-64. Doesnt' make sense to me that something has to be done to the car to account for change in seasons (i.e. A/C to heat)??? I have an '08 g35x.
