I just bought a Saturn Outlook and I'm having a problem with my rear air conditioner. The rear air blows out much warmer than the front when the air conditioner is on. We have the Auxillary switch on. From the rear controls we can make the air warmer but the air is still warm on the coolest setting. We took it to the dealer and the Tech said there's nothing wrong with it. He suggested keeping it on Auto and recirculate all the time. I'm not sure what else to do. Is there something I can tell the dealer when I take it in that will make it more likely for them to find the problem? Does anyone else have this problem with their Acadia? Any suggestions would be appreciated. Thanks!
