.... okay.

your mustang is a FORD

you have a cobalt which is a CHEVY. don't bitch about chevy wanting the interior of their cars to have fresh air. if you dont like it why dont you put the temp dial to the middle and throw some duct tape on the ducts?

 

Getting ugly in here.

 

Turn the fan to the off setting and hit the recirculate button .......that closes the vents /

 

Every car I ever owned did this. hit recirculate...

/thread

 

You think its bad on the cobalt? Try a solstice... with the dial at zero, it feels like a 3 on the cobalt...

 

its normal operation for the cobalts whats messed up is that if you put your selector knob on the floor setting it engages your defrost which is run off your a/c line. but if you put it one click towards the face side its shuts it off. now thats annoying.

 

I remember in my Acura manual it recommended leaving the fan to run low speed all of the time. Reason was because the cabin filter would get a musty, kind of stale smell to it.
I just leave my fan setting on 1 all the time.

 

 

Interesting. That's not a bad idea especially if the user engaged the A/C during the summer. Remember the old musty smell the next day? I wonder if GM did this on purpose to avoid customer complaints about this problem. With the cabin air filter, spiders and leaves shouldn't enter the ducts anymore.

 

Okay, here's the deal:

When you go to 0 on the dial, the fans no longer run. The air comes in (as it does on most vehicles) through the vents right in front of the windshield. With the car sitting there, hit fan speed 4, for instance. You'll hear and feel the air going in there. You won't hear/feel it in the 0 position.

The air that you feel is the flow-through that's basically getting rammed into the vents either because there's a lot of wind or you're driving around. Unless it's the A/C, the HVAC doesn't know that you don't have the fans on or off, so the temp dial will still work. All that knob does anyway is change how much it heats the air that goes through it with engine heat. Some of you claim that you didn't feel air from other cars, but you probably just didn't notice it. In my old Tahoe, even if you had the air on the "face" setting, when you turned it off, it redirected it to the feet until you turned it back on.

This is typical for many makes and models of cars. For our vehicle in particular there are four solutions for you to choose from:
1) You turn off the fans and enjoy the air coming in.. you can still heat the air. The cold setting is basically just the flow-through. It will never be any colder that the outside air (unless you recently ran the A/C and the air ducting is still cold).

2) You turn off the fans and then shut the air vents. The is done by the knob on the side of the air vent. Rotate down until it clicks. The vent actually forms a closed surface when it's all the way down. (I do this very often to the passenger side when nobody's with me so I get more air)

3) Turn off the fans and turn the HVAC direction knob to another location, such as the feet. You won't feel it blowing on your face and it will help keep you feet cool/warm if nothing else.

4) Turn off the fans and hit the recirculation button. This changes the source that it gets the air from from the ones in front of the windshield to another interior location. Since the interior of your car doesn't have ram air happening, then you'll stop feeling the air. This is also a good thing to do when going through dusty areas as it won't blow a bunch of dust/whatever into your car.

 

This has done this in ALL GM vehicles since 1972 No **** im not kidding.
Its GM's trademark

 

FASTL61: Thanks. This is my first GM vehicle. I'm glad I didn't own any GM cars that didn't have cabin air filters. All that dust/dirt from construction sites would get forced into the cabin unless you had time to engage the recirculate button. The Ford system seemed to have been designed with common sense: the operator shuts off the system and it stays shut.

 

You've got a cabin air filter on this vehicle. It's located by the glove compartment.

 

Have you guys noticed that recirc isn't persistant on this car? Drives me nuts to hit the button all the time. I drive in the city quite a bit and don't like "fresh" exhaust air in my cabin.

Just yet another little "thing" that often annoys me. DO WHAT I ******* WANT, CAR.

 

its just vent air as you drive, normal

You wouldn't want to drive with no fresh air coming in
