Back at it again, this time with a GMT900!
I have a buddy that owns a 2013 Z71 Tahoe 4x4, it is pretty much loaded. It was however outfitted as a PPV vehicle. He is the 2nd owner.
I appears to have the whole 9 besides the rear seat delete for suspect containment. However it has a partial console install. All the lights retain their flash ability with the control module removed but it seems all blue and red interior and exterior lights have been removed.
Now they have owned the truck for about 3 years, and drive it about once a week.
Recently they have had the battery start dying overnight. No obvious issues, all interior and exterior lights appear to sleep, a long with the cluster and radio. I did a parasitic draw test via a multimeter online with the negative battery cable.
KOEO, at about 110.00 mA then as I pulled fuses from the under hood fuse box and the dashboard driver fuse box. Never saw a drop from an individual fuse however over about and hour of troubleshooting it dropped to about a steady 49.3 mA
Initially it would start at 110 then slowly drop to about 60-55 then after an hour of pulling fuses it would hold at about 49 only spiking when I reconnected the leads or had to turn the multimeter back on.
I have not yet pulled fuses from the driver side foot well area as I ran out of time.
They have complained of the back glass randomly popping itself open going down the road and did notice a rodent issue also in the back cargo area that was solved with traps. Those two issues didn't immediately cause the battery draw but were prior to this issue.
Any ideas? I'm still learning electrical so please bare with me.
