Yesterday when I got home and shut my car off the fan kept running. I have seen this before in cars and thought nothing of it. But, then I went out to smoke about an hour later and it was still running. So, I started it up and ran it for about a minute and shut it back off and the fan went off. The temp here was about 50* yesterday, so it couldn't have gotten that hot. Everything has ran fin before this and ran fine this morning, it just seemed strange...

Anyone ever had this happen, or know why it may have happened?
