@M1Gunner, great post!
I know this is an older post but this just happened to me today on my 2012 Yukon....coldest day of the year!
I go out to ck my car earlier and the battery is dead....dead, dead. Anyway I charged the battery, yes it's only 1 year old. So then the door latch got boggled up and so the door won't close. As I'm trying to figure that out, I work on it for several hours, can't get the latch to go back into the right position. I finally give up (it's dark out by now) I turn the car off and the gauge lights and radio stay on.d..I fiddle with it a bit and realize that's why the battery was dead/ I drove the Yukon a couple of days ago in the daylight, didn't realize when I did the radio and gauge lights didn't go off.
So, since tomorrow is a holiday and it's so fricking cold out I'll try to get into my mechanic on Tuesday or Wednesday. I don't feel like messing with it.
