My car keeps dying overnight and needs a jump to start. I took it to AutoZone to run diagnostics and check the battery and they said everything came back good. Said maybe could be from the cold weather but this happens every morning now.

This does sound like a bad battery, but if the car has a CD player check to see if there is a CD stuck inside. if so, this will run the eject motor all night long. Also, I have seen the A/C compressor relay stick on which will cause the same problem.

Please go over this guide which should help as well:

Here is the location of the relay so you can remove it to see if it makes a difference which is under the hood. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
