2003 1500 ext. Cab, 5.3L automatic, 45K miles, has a battery drain after car is powered off. Battery has been replaced, alternator load tested. Battery is dead every morning. I did a parasytic drain test, found out that if I pull 15 amp radio fuse under hood, battery does not go dead. Is this a radio problem, or a BCM problem? It sounds to me the radio functions are not going to sleep as they should, and I know the radio controls and depends on a lot of things. Where should I start?
have the same problem?
