I have a 2010 G37S. Is there a way to allow cool air from the outside in the car without turning on the climate control? I know this is a more modern car but in previous vehicles I've owned there was a vent mode that just let fresh air to come inside the car. The G seems to not allow this even when in fresh air mode.

 

LOL... yeah of course there's a button you can push to let the air from outside. next to circulation button.

 

Yeah tried that but it doesn't allow the vents to open and allow air from outside the vehicle to come in at speed. Maybe I need to see the stealer.

 

should be work, because i'm using that every morning

 

when the AC is off press the "Mode" button on the control panel. it should bring up the option to choose which vents you want just the air to blow through.

 

Yeah AC has to be off for it to work.

 

 

I second BigJack. My two G37's (coupe and sedan) do not blow air into the car when air circulation is set to blow in air from outside and a/c is off, top air vents are open. My mom's corrola and my friends honda do a much better job than my G's. My cars turn into an oven. Either my windows need to be down all the time or a/c needs to be on all the time. Made sure a/c is off and climate temp is set to 60 degrees, made sure only the top vents are blowing air, and "fresh air" mode is set. I have to be doing 80+mph to feel a small amount of air come through the vents. A/C and heater work perfect though. anyone else have this problem? any suggestions?

 

In my '09 sedan, I just have to have the A/C off and can have air from the outside. Fan is always on, but you can have it vent from the outside.

 

Ok so the fan needs to be ON in order to feel outside air through the vents? Does it waste gas or cause mechanical issues having the fan ON all the time? I'm just use to my other car that would blow air through the vents ONLY while driving at fair to high speeds (speeds of 35+mph) and wouldn't blow any air while at a red light or going 10mph. And if it's a cold night I could put the temp on HOT and it would blow in hot air using outside air. But it sounds like I need to have the fan running if I don't want to roll down my windows, don't want to use my a/c and I don't want to sufficate in my own car?

 

The fan will be pulling a minimal amount of amperage from the alternator. That's about it. Just realize that there are countless other G owners in the desert and snow regions have the fans on constantly with A/C or heat the entire time they drive their cars (as well as just about every other car on the road in those regions).

 

I bought my G in 2007. I have only turned the climate control off for very short periods a handful of times. Not just the fan, but the AC compressor. Occasionally the heat, so running the compressor to defrost windows. Running it 24/7/365 isn't a problem.

 

I do the same. The A/C is on constantly unless it's extremely cold, even then the compressor is on for defogging the windshield.

 

Great, Thank you Flakman and B. Betty for clearing this up for me.

 

My understanding is it is actually better for the AC system if it runs more often. Older cars, it was possible to go several months without ever engaging the AC compressor in colder climates. Essentially your system sits dormant and slowly rots. The new cars now force the AC compressor to come on much more frequently, even in cold temps. It keeps the fluid inside the system cycling and keeps all of the seals and parts lubed and moist.

That is what I was told anyways.
