Is there a "trick" to keeping the air conditioning off? Before recent repairs (new ignition), the air conditioner would remain in the "off" position even after turning off the car. Now, after the repair and subsequent re-coding for the the door locks and windows, the air conditioner is in a default "on: position every time I go to start the car. It will turn "off," but it will be "on" again once I re-start the car. Itried holding the power button for ten seconds but that didn't work. Is there some sort of code needed? Can I perform some sort of voodoo on it?
