So if I understand your response correctly, at startup with a cold engine, you would rather have the fan higher (maybe 3 or 4) blowing cold air out the dash vents into your face until the car warms up??? If that's what you want, go for it, that's why there is a manual mode.

I don't understand it and probably won't... To each their own...

 

Another little detail: I turn off the climate control on start up, let the engine warm up first, then turn on the vents. A few seconds of "dead space" cold from the vents I can live with As much as most here swear by the auto mode and as much I wanted to learn to like it, it would rarely do what I wanted it to do. To each their own - agreed. My only wish is that Infiniti had made it easier to use manual climate controls by making the buttons sized/shaped differently for adjustments by touch without having to look at the dash every time.

 

wtf only the right side of my cars heater works. Both sides are set to 80 degrees and only the right side comes out really hot and my side comes out cold......... why?

 

so i've had the indoor battery operated thermometer in my car the past few days. i kinda keep it on my seat. in the morning i get in the car and its internal temp is 66 degree. I hit the auto for 72 and 15 minutes later the battery thermometer climbs up to almost 71.

It sure doesn't feel like it, but i guess my heater does work.

 

Great. Glad my idea worked.

I think there is a huge difference between actual temp, and how it feels...

For example, naturally after leaving the gym, I usually turn it down from 70 to 62!!!! Nothing changed, just me.

I also find during summer, in the morning I like it at 70 (72 feels way to warm.. no sun), but in the afternoon (full sun) I have to turn it to 72 because 70 feels way too cold. If the car senses sun it tends to blow a lot of cold air at you. So between these two things.. you have to adjust it.

I do have to say my last car was a Subaru legacy GT. That auto climate control was HORRIBLE!! I was constantly adjusting it... This one works as it should.

 

Why does the A/C turn on when outside temp is 50 and inside temp is set to 80? Does this mean the compressor is running and burning extra gas?

Had the car since may, and this is my first brush with cold weather.

 

This must also be your first car with auto control HVAC. The AC runs in full auto mode. It helps to dehumidifiy the air and keeps it quite comfortable. Especially true in cold rainy weather. It actually cools and dehumidifies the air, then heats it.

You can simply leave it in auto, and shut of the AC if you don't want it on. When it gets really cold (30 degrees this morning for me) the AC will say it's on, but it won't run if there is a chance it will freeze.

 

My '92 Q has "auto" and "econ" buttons. I always use "econ" in winter.

What's annoying in the G is that if it's cold outside and I set the temp to 80 and change the fan to blow from the main vents (cold hands!), to get back to normal I have to push "auto" and then the A/C turns on again.

Is it normal on a lot of new cars for the A/C to run in cold weather? I realize that there may be a subtle benefit by controlling the humidity, but isn't burning extra gas by running the compressor more of a concern for most people?

Or does the compressor only turn on periodically in this situation?

 

The compressor always runs peridoically no matter what the temp. It will always cycle even if it's 90 outside otherwise it would freeze up.

In any event, you do have to hit auto, and AC off. It's the way most cars are. I do find it funny that you are complaining about cold hands in Atlanta though... I am in Vermont, so the definition of cold is a little different.

The gas savings from running without AC is very minimal. You would save much much more gas if you were to buy a Prius over this car. The other thing to keep in mind, are reapairs. I read an interesting article the other day. To run the AC a lot actually better since it circulates the lubricant that is already in the refridgerant. If it doesn't run for long periods, seals and things can dry out. This is why they suspect they have much less AC repair issues now that a lot of cars use the AC much more than older cars did.

Hope this helps.

 

I knew it was good to run AC in winter but I figured running the defroster now and then took care of that.

My only other concern about the AC is the swampy/moldy smell when you run the AC too much and don't air it out (I try to turn the AC off a few mins before I reach my destination in the summer). I hope that's not much of an issue in the winter.

I think you've convinced me it's not worth worrying about, I'll just leave it in auto and see what happens.

Are there any past threads where this was discussed? Or am I the first to bring it up? (search function doesn't like "a/c" or "ac")

 

Guys this is my first post.

Where is the ambient switch?

Im new to the car .. I have sedan 2003

heat won't get any hot air until i press gas other than that i get cold air.

 

I am having the same issue (heat when driving, cold air when sitting)

??? I have searched and this seems to be a common issue, but what is the fix?

My Temp gauge is working correctly, and the car idles properly - is it a safe bet that my thermostat and radiator is functioning correctly?
