Yes, I'm dealing with this problem now. I've had it in several times (they tried to tell me it's just a software update that was needed), but it only fixed it for 24 hours. I finally convinced them that the HVAC control module needs replaced (after researching on the Internet), and I'm currently awaiting for the part to come in and get it installed. I'll update you when it's fixed.
Out of curiosity, is anyone else with this problem using a superchips flashpaq on their Jeep? I have my suspicion this may have caused it, but the problem persists even after removing the programming.
