vents are coming on and is blowing warm air run battery down after car is off on 2009 Chevrolet Traverse

the air comes on and blows until it runs the battery down and has to be given a boost to get it started. If you catch it in time you can take the key and turn it onto stop it. sometimes it comes on a hour later after the traverse has been off. Is this an electrial problem or what?
