Is this something in the switch or is it elsewhere? In the computers? Once I jumped it off it ran fine, volts were great, etc.. I put it on the battery charger when I got it home, just to be sure as it was really drained. Any tips of things to troubleshoot appreciated. -Woog
hi, its the switch in the door, not working properly.

this thread should help, I had same issue on my 2008 envoy, but only on an incline. when truck was level it was fine.
I cleaned latches with brake cleaner, then contact cleaner.
, seemed to do the trick at least for now.
