05 H2 Battery Drain after few hours, any thoughts?
New Battery.
No after market accessories.
Pulled on star fuse, still drained after sitting for 5/6 days. Should i pull out the on star unit?
Gone through lots of posts. Recommended shut off factory alarm and shutting off light switch override. Are these options in the DIC menu? I did buy all new glo fuses to replace all the fuses, would that help out at all? Thank you everyone.

for me it was the dealer installed XM radio module that was draining the battery. it was not working properly when i purchased the truck. removed the module and its wiring and my problem went away. i was getting a u1000 code on the scan tool and it would not see the XM unit. thats how i located the issue.
