    Climate Temp changes are dramatic

    I have a firebird Blue XTS I love it but I was on a trip coming home from out of town and I noticed that even thought the temperature on the passenger said was one degree warmer it was blowing probably 10 degrees or more hotter air. I can have my temperature set to 61 and the passenger set to 63 and it feels like it is blowing hot air from a cold winter morning. This is pretty bad when it is already hot outside. Is anybody else having is problem?

    Had a similar issue returning home from an extended weekend at a hotel. Seems the hotel valet attendant turned off the AC. The entire trip home the AC would kind of work and then not when I hit Auto. I was trying to control it from the haptic touch buttons under the display. No good, they control the fan. I finally went to the climate screen in CUE and sure enough the AC was off. Touched the AC button on the screen and all was well again. Perhaps this is what's happening with your AC. Good luck.

    I thought it was that but the ac or cold air would come on super cold so i adjust the temperature and by one degree or more and super hot air would come out the passenger vents but cold air our of the driver.

    Is your A/C set in the SYNC Mode? If not then the passenger temp could be set way too high. If it's not in Sync then whenever you adjust the driver's side it only adjusts the driver's side and not both. Bring up the Climate screen. If you see the word SYNC then tap on it. It will synchronize both sides of the car.
    I hope that's it.

    yeah thanks for the info but it wasn't the sync setting. If i change the temp up just 1 degree it has a huge difference like 10 degree. I am going to try and reset cue and maybe that will fix it

    There are numerous software updates for the XTS. One is for the HVAC control module involving temperture concern. Take it back to the dealer and have the service advisor check to see what updates pertain to your VIN.

    YES. You can call your advisor and give him your VIN information, then they should be able to go to the GM site, type in the VIN and check for updates pertaining to your vehicle
