I have a 2014 GMC Sierra SLT Crewcab, 2 weeks old. I have noticed that when I have the air recirculating in the cabin, outside air closed off, I still am smelling outside air, cigarette smoke from the next car while sitting at a light, bus exhaust, skunk smell. I also have a Buick Enclave ('11) and my old Silvefrado ('03) which did not permit outside air from entering the passenger cabin when the 'recirculate' button was in use. I is almost like the 'door' is not closed completely. Has anyone else experienced this?

So I'm a little confused on the HVAC controls on my LTZ. In the good old days (GMT-400 and maybe 800's) you could switch the AC compressor off by pushing the AC button, no matter how hot or cold you set the temp knob or button to. On the current truck that doesn't seem to be the case. If I set the temp to say, 67, the truck keeps on cooling it seems, no matter if I have AC button on or not. So what gives? Obviously the HVAC system is basically doing its own thing to keep the temp where I set it. This is with the system NOT set to auto, btw. Can someone in the know shed some light on the technical operation of the system? Maybe a PDF from GM explains it somewhere?
