Hello,

The car AC let's in outside smells even when the air circulation is set to recycle, if I'm in a smelly area or I'm behind a bad vehicle with bad exhaust smells it all goes into the cabin, only way to stop it is by totally turning the ac off, I took it to the service center and they checked the ac unit and changed the filters and checked the buttons for circulation they told me that all is working fine and that the vent flap on all Chevrolet's only close for about 70% hence why "Some" of the smell is coming in, but this isn't my first car and this is clearly not normal the car lets in 100% of the outside smell not 30% please tell me what to do... My throat hurts especially from smelling all the car fumes daily in traffic..

They aren't wrong. The car does still bring in a small bit of outside air in recirculate. All modern cars do. Perhaps you might want a charcoal cabin filter as well.

However, your flap may not be working as intended. This may be what you're looking for:

Ya but what I'm experiencing is not a small bit of outside air it's all of it!!! As for the flaps they told me that they've checked them and that they are working properly.

So I checked the interior filter compartment for the flaps, the top one doesn't move at all.
And the front one works but the whole process is reversed, it opens and takes outside air when I want recycled air and closes when I want fresh air and it doesn't even totally close!
The frustrating thing is that the service center told me that its all fine and that they've checked the flaps too which they clearly haven't!

Our CRUZE is supposedly equipped with an AQS sensor although my model doesn't seem to have one. Worked great on the Sonata, like bad smell Radar that would send the unit into recirculate. Aside from some isolated coolant smells I don't get any excessive odor at all keeping the system in fresh mode most of the time

Only LTZ has that feature.

OP, My 2012 Cruze had the HVAC head unit replaced & recirc flap recalibrated because mine wasn't closing when recirc was called for either, and fumes were coming into the car in heavy traffic. I'm not sure if it just needed recalibrating like Blue Angel mentioned in that thread or not, but once they did that warranty work, it worked fine from thereon out.

I'll ask them to check the flaps and the HVAC unit thanks a ton guys.

My cruze is 2014 LS so I believe that it doesn't have the AQS sensor
