As it says I would like to know if it's possible to turn the stupid three zone AC off and have it function as a one zone system....ie the temps in all three areas go up and down at the same time rather than having to adjust three separate controls. Who ever thought it was a good idea and thought it would actually work was clearly drunk...the warm air on one side of the car can't stop mixing with the cold air in the other or the middling temp air in the back...ie all ends up one temperature anyway! I've read a few suggestions on this site such as pushing and holding the drivers AUTO button and a couple of other ways...none work. Nothing in my manual either. Mine is a later model without the MONO button the early ones have...pity. Anyone know....thanks in advance if you do!
