Is there a way to leave the rear AC always on when you enter the car. I have tried rear seat belt plugs and activating the child seats. But nothing has worked. I have a dog and when he is with me and lays down between captains seats in rear (6 seater) the AC will not go on unless he jumps on the seats. I know how to activate it, but I hate having to do it each time. Plus live in S. Florida and the car cools and maintains temp better when all vents are active. Anybody figure this out?
