• Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

My brand new telluride S’s AC will sporadically not work. Sometimes when I turn on the car it works great, other times just blows non-cooled air. Major issue in AZ. Does anybody else have this problem? If so, what do you do?
 
Bring it into the dealership to be checked out and fixed, especially since it is within warranty.
Just checking the times it is not blowing cold, is the ISG on? I mean, is it when you are sitting still at a stop light or traffic?
 
Probably warmer when engine turns off to save fuel. Is that your situation?
 
No. I turned the auto engine stop off and It’s still warm when I’m moving too.

Did some troubleshooting. Ot will blow cold air if I have the rear climate control on but stops blowing cold if I turn the rear off. Any ideas?
