Heat stays on while car turned off

Hi there,

So my heat stays on while my car is turned off and key removed. All positions on fan works (1-4). The only way the heat turns off is when I actually turn the fan off (0 position) first, then turn car off. Any ideals? Thanks. Much appreicated.

Anyone out there i need help on a 2001 elentra heater fan staying on at all time even with ign key off.All fan speed works 1-4
