I use all the correct steps listed in the vehicle manual to turn off (disable) the rear climate control button. I do this in conjunction; using all of the assigned controls on the front panel (on the dash), the front monitor (plus I activate the "locked" button on this monitor) and the rear climate control panel that's located in the ceiling over the second row captains chairs. My problem is the rear climate control will not stayed turned off. It deactivates (turns off) for a period of time. Sometimes it lasts for a day, and other times just several hours. I don't want it running unless I actually need it, as it's a needless electrical draw on the system, and I don't care for the noise it makes as it vents through the extensive rear climate control system. I'm at a loss how to keep it turned off, and would appreciate any advice you might have here. I will eventually contact the service manager at the dealership, but don't expect too much help, as it's too new a vehicle to have a history on. Any advice you could give me would be greatly appreciated. Joe
