I have 2008 GMC Sierra 2500 HD 4WD with battery drain issues. Service shop cannot find the problem. After watching youtube and reading responses on this site, I will check each fuse, be sure all extras off before turning key off, and see what happens. Thank you to all who posted ideas.

Hi. I love this truck once it starts. Several mechanics have checked it out. New battery, starter and alternator fine. After 3-4 days of non-use, battery is drained, no lights or anything, totally dead. Nothing coming up on the service shop codes. Any other ideas? Thanks.
