Hello,
I have a 2004 Z71 Suburban that kills the battery after a few days with no use. Battery is relatively fresh, alternator charges fine, already pulled the OnStar fuse and the radio fuse.
I measured the draw on the battery with the vehicle off and everything to sleep and it is 0.18 amps. I individually pulled every fuse, relay, and fusible link and when I pulled Ignition A the draw went to 0.00.
My local mechanic won’t do ignition work and the dealership is backed up for weeks.
Any ideas on how to fix this?
thanks!
