Blower fan stays on after car is turned off
 

I have an issue. I just cut my car off the other night and realized when I went to get out the fan was still running from the heater. I switched it off then back on and it still came back on even with the key out. I jiggled the key in the ignition to see if it maybe had not been turned all the way but indeed it had. Some of the lights are even visible on the climate control itself. However if I mash a few of them, it cuts itself off. Weird. Anyone have any ideas or had this happen to them?
