2006 GMC Envoy Denali
I've read many posting here about this topic and watched numerous videos as well.
The battery seems to be dead after an overnight. It used to take a couple of night but now it's just one.
The folks here seem to be the most knowledgeable in this area.
Here is the short version
Battery and alternator have been replaced and are confirmed good.
Instrument cluster was repaired due to excessive lights burned out but also to see if it was contributing
to the drain. I don't know that they were truly able to determine if it was an issue.
Checked drain at all fuses after waiting for the sleep and recorded drains.
I have gone through many wiring diagrams and haven't been able to determine much.
Any assistance would be greatly appreciated.
