the a/c realy may be part of the a/c control module per all data,or the a/c control module just lost its memory. i suggest you seek help on this as to not cause further issues.when changing a battery in the newer cars you must keeep memory alive using a pwr box as to not cause other issues. sorry but it could be several things. you can try www.alldatdiy.com
