    Greetings,

    I have a 2003 Chevy Tahoe 5.3 4x4, I am having problems with my battery draining overnight. Found some info on BCM issues online. Had my wife take it in to local Chevy dealer to repair or replace BCM. Two days later I'm having the same problem. Because of my work schedule I was not able to take it in myself so didn't get a chance to ask questions or find out specifically what they did. I'm desperate for help and to get this problem resolved because it is preventing me from passing a smog test. Anybody else have similar problem or heard of this problem?

    Did you have them check out the battery problem or just instruct them to replace BCM?

    How old is your battery?

    Do your vanity mirror lights go out when you close the flapper door? Mine didn't.
