My 2004 silvarado will be dead in a day and a half. The battery and alternator are new. After everything has gone to sleep the total draw is point66 MAs. Stud 2 was 0.24MAs and HVAC was 0.33 MAs, I didn't chase the last 0.09MAs. I don't understand how it can go dead with that tiny draw. I pulled the fuse for stud 2 yesterday and it barely started today. When I got home from a long drive tonight I pulled the HVAC fuse, I'll saee how it does tomorrow. Thanks for any ideas Mike

Depends on how fast you need to get it fixed. The easy way would be to pull all of the fuses, leave it overnight, and see what happens. If it is still dead, you can chase something before the fuses, and if not then you know it is something fused.
