    Hi everyone. New to the forum. I have a 2002 Chevy Suburban with a killer parasitic drain on the battery. I've read all the thread in this and other forums and I'm still stuck. I can't narrow it down to just the BCM. The only way to kill it is to pull the under-fuses marked TBC, RADIO, and SEO1. But none of the three is a consistent portion of the draw. It is driving me nuts. Anyone out there with some tips?

    Does it has lighted mirrors on the sun visors? I have seen the hinges do bad and the lights stay on when they are closed.
