Does the c6 recycle air button let in air or no? Every other car I've owned let noticeable (through the vents) air in so that when I didn't want the A/C on but was a little hot that would cool it down.

I bought a used c6 and haven't noticed any air coming in so I'm wondering if it's an issue or that's just the way it is

If you're talking about the recirculation button, 2nd button from the left, while it's lit, no outside air is coming in.

Yeah, that button. I'm referring to when it's not lit

Yes, it's supposed to let fresh air in when the light's not on. I'm pretty sure even when it's on recycle, it still lets some fresh air in for safety.

When you press that button and it lights up, it not only keeps the outside air out, it also turns the fan up a notch (if the system is on). If the system is off it will effectively keep any air from moving into the cabin. When that button is not lit, it allows the outside air to be force -fed (at a verrrrry small amount) into the cabin depending on the speed of the car, even when the system is off. When the system is on, it allows fresh air into the cabin at the fan speed.

So is the air that's coming in noticeable/feel-able through the vents?

I've only had cars with manual A/C controls before and those would let the air in at whatever temperature the controls were set at. Not sure how it works with digital/electronic controls

owc6

Correct, if the recycle button is not lit, it still lets some outside air in. Usually at the temp that was set when the system was shut down. For example: if the temp inside was set at 90 and you turned it off, it will still feed hot air, and when you find that your feet are burning up, even though the system is turned off, you will need to turn it on and turn the temp down. Let it engage enough that the fans start and then you can turn it off at the new set temp. It will then feed the new cooler air to your feet, or wherever you have it turned to, at a force that is dependent on the speed of the car.

The C6 climate controls will not let you just draw in outside air without adding either heat or cooling to it. Very few cars now days will let you pull in untreated outside air.

pk5

Hmm if I can't feel any air at all coming through when the light is not lit, something's probably wrong?

pk5

Got ya. That's what I want - outside air coming in at whatever temperature it's set at (so I don't always have to turn the A/C on) - but it seems to be not working

owc6

You aren't going to get noticeable airflow through the vents with the system off, if that is the question you are really asking.
Which doesn't negate what I said earlier. lol

Regardless of the recirculating button, you can still get nasty smells like skunks and cars that over pollute.

You could have a clogged up cabin filter. I bought my car with 60k miles, and it looked as if it had never been changed. New filter made big difference in air flow.

A friend changed his for the first time at 45k miles, and said "now my heater works again!"

HOXXOH

OK, so now that convinced me it needs changed. I changed it the first and only time around the 30K mark and now I'm at 116K.

Wow, with that many miles, it's probably bad!

By "safety," we will all assume you mean "as a way to offset the burrito supreme I just consumed."

Another important function of the RECIRC button is to prevent warm air from coming out of the vents in the footwells in the summer. This is very noticeable when it is warm outside and the top is down or the roof panel is out.
