( 2006 Chevy 2500HD LBZ ) I disconnected my battery's today and lost my timed delay power to the radio, windows ect . after the key is shut off while sitting in the truck with the doors still shut. Also when putting the gear selector in gear the automatic door locks and unlock no longer work as well as the delayed dome light after leaving the truck with everything shut off .... anyway to reset back to the way it was ?
