I'm also having climate control issues with my 1LT but its not dual climate control, basically when set to 80 its blowing cold air out the vents and I have to set it to HI before it blows anything close to warm and its doing the intermittently.
What can we do to really raise an issue with GM? The dealer is refusing to address this. |

"Some vehicles also use passive infrared sensors mounted in the dash or in an overhead console to monitor the body temperature of the vehicle’s occupants. This allows the system to fine-tune heating and cooling output so everybody stays comfortable." http://www.underhoodservice.com/auto...ntrol-sensors/ BTW - in some applications the sensors are installed in the control panel so they arent listed as separate parts - if they were to fail (they usually dont), you would have to replace the entire control panel. Has anyone identified the sensors for the Camaro (there has to be two for dual climate controls to work). Last edited by mekirk2; 03-26-2018 at 06:39 PM. |

I know Im a country hillbilly with no formal teachin' and all, but you reckon our 2016-18 Camaros might have technology that was available in a 2008 Lexus (if not older - this is just one of the videos Ive found):

Someone whom has service manual and can quickly answer that question. But, we are taking about a Camaro not Lexus. I don’t see these sensors in my car unless they are mounted in vents or bluetooth speakers.

They are usually part of the control panel itself. Ever notice how hard it is to see the IR receiver on a tv? They are easy hide. Not sure if the service manual will list them or not - does the service manual list the volume knob on the radio as an individual part? |

I hope Mopar didnt beat us on this - in a minivan of all things. I doubt it though. Like I said, these things have been around, in one form or another, for a long time.
"2008-2017 Dodge Caravan / Chrysler Town & Country climate control repairs ImperialCrown wrote about the common problem of having cold air coming from one vent and hot air from another: In models where the interior temperature is “watched” by dash-mounted infra-red (IR) detectors, sometimes the IR lens can be obscured by things hanging from the rear-view mirror or a coating of tobacco smoke residue, or other dirt. This can interfere with automatically regulating the interior temperature of automatic temperature control vehicles." https://www.allpar.com/model/m/repairs/RT-climate.html |

Humans normal temperature is 98.6 and feeing hot or cold, or desiring a warm or cold breeze from the Cars climate control system, does not change our bodys temperature. My wife could be 98.8 and feel freezing, and I could be 98.4 and feel hot. IF these systems can detect minute differences in body surface temperature....Im not sure why it would contribute to a better climate experience. Strange IMO. |

Here's something to try - start the car and then immediately get in the passenger seat (dont let the drivers seat warm up from you sitting in it). Make sure the seat heaters / blowers are off. Sit there for 5 minutes or so with the doors closed and see if the temp of the vents swap sides from what you are experiencing when you are in the drivers seat. |

@ mekirk2 while this is all interesting news and I don't deny the presence of the technology in modern vehicles, I have my doubts its implemented in our cars. My heat for example at 80 degrees got HOT.. and I mean so damn hot I had to crack a window while turning the blower COMPLETELY off and I would be COOKING inside that car. I'm pretty sure my body temperature at that time was set to "broil" and that thing was still kicking out as much hot air as it could even with the system completely OFF... Later its 40 degrees outside and while I'm not FREEZING, I was nowhere near as hot as it was when it was just bawling out hot air on me.. ..my body temp I'm sure was much lower.. ..so I'm heavily doubting this is the case.. ..but it would be nice to have confirmation on the presence of these systems because GM mechanics are claiming that systems similar to this are present in the vehicle as well.

We all know how well technology implementation can go The tight space in the Camaro may make it more difficult for the system to work as well (just a guess on my part). I do agree that the system in the Camaro is more flakey than my other vehicles.
Many people don't understand how the 'auto' feature works on modern cars. In old cars, when you want to cool down, you set the temp setting all the way to cold, turn on max air and run the fan on high until you were comfortable, then you turned the fan down and maybe turned the temp up a bit to keep from freezing. The temp control switch controlled the temp coming out of the vents and that was all. In the new systems, when you click 'auto' and set your temp (say 71), the system does its best to regulate the temperature around you. So, when you start the car, the air blows ice cold until the car cools off and then the fan slows / air temp increases out of the vents once the target temp is met. Auto climate controls require some type of ambient air temp or body temp sensors - usually IR sensors now because they are pretty reliable and cheap. Most cars are even smarter about it though. My Nissan Titan, for example (2008 with auto climate control) will not activate the system in winter until the truck engine is up to temp. So, when I start the truck in the winter time, the heater blower does not start to blow for the first 3 minutes or so until the truck is warm. In the summer, however, the system starts blowing immediately because that AC pump is already spinning. I leave the truck on 71 year round and NEVER touch it - it does a great job of keeping the truck temp comfortable. My wifes 2014 Grand Cherokees climate control system does not do near as well as the Nissan. It amazes me how integrated these systems are with other car systems. They use the outside air temp sensor, vehicle temp sensors, a sun sensor on the dash, as well as multiple sensors in the vent systems to regulate the temp. I wouldnt go back to the old way if I had a choice Last edited by mekirk2; 03-27-2018 at 07:34 AM. |

Want to see something I think is pretty cool - check out this guy troubleshooting a 2010 GMC Acadias auto climate control system. Especially the test equipment - apparently these systems are also able to store trouble codes. I thought the number of sensors listed in the software was interesting as well:

As far as I can tell, nobody reporting problems here has gotten that kind of detailed feedback from the service dept., just "it's working as it should." That's not the same as, "We checked the readings from all the sensors and actuators and they are all within spec." Those with stubborn dealers should grab a probe thermometer from Amazon or Harbor Freight and keep it in the car so they can make a cell phone video when the system acts up. Sorry, but if you set the temp at 68 the duct should not be blowing 80. |
