Is the battery old? It's possible the battery has become weak and this cold weather really drained it. Cold weather really does a number on batteries. Most shops can test the battery for you and many auto parts stores will test it for free if they have the tool. It's possible something else is draining the battery when the key is off but that would require some basic electrical knowledge and a multimeter to diagnose

my 2002 yukon denali is recently having the same problems for the past two years. I have had the battery replaced three times, a new alternator, and a removal of a dvd player. I am still having the same problems. Can anyone help me?

I have a 2003 Yukon Denali that had similar issues. After many visits to the dealer and a local battery shop to help diagnose, I forced the dealer to keep looking to find the true root cause. It ended up being a problem with the ground connection to the frame that had a low potential across it, slowly draining the battery.

Check to see if your climate control blower continues to run after youve turned off ignition
