I've noticed sometimes when I go to get in the truck, my rear vents are blowing. It's intermittent and it'll run for various amounts of time and shut off. The engine is off and key isn't in the ignition. I usually only notice it when it's pretty hot out 90+. I've wondered if opening the door activates them, or hitting the unlock button... Not sure. Is this normal for an 2007 Yukon with auto climate control?
I've been trying to figure out why my battery keeps randomly dying. There's no rhyme or reason to it these days, it's completely random. In the last week I've had to jump it twice after driving to lunch (10 minute trip maybe) coming out 15 minutes later and it won't start. It's not completely dead, but just not enough juice to turn over. I jump it and it's fine.
I hooked my multimeter up to it last Saturday, and tested the voltage after a full charge. Fully charged it ran 12.65v after about 4-5 hours, 12.5v. It got as low as 12.45 but not really much lower. I started it and repeated to find the same thing. So I measured 14ish when idling and 10-10.5v when cranking. Checked for a parasitic draw and didn't find one other than a 4a draw for about the first 30 sec. but that dropped to 0.01a. Lastly, I took it to Autozone and had them test the battery/alt and everything passed.
Convinced it was my battery anyway since the alternator is relatively new, I replaced it today with a Auto Craft AGM battery. The battery I had before was a Delco Professional 48-6YR manufactured in 6/10. I'm still not so sure it's the battery with all of the testing doesn't indicate it's bad. I'm wondering if the vents are randomly turning on and off when the truck is empty and killing my battery in the process?

and my old battery has held it's charge fine after removing it.
