Heater blower won't shut off....

Unplug the high speed relay mounted near the blower motor and see if it shuts off. The relay could be stuck closed.
 
Do you have the standard lever style heat controls or the digital touch-sensitive climate control on your dash?
 
I have standard heat controls. There are two wires going to the fan, the power wire with the black plastic attached, and one next to it. Unplugging either one shuts the fan off. Is the relay part of the fan?
 
Picture shows fan relay (yellow arrow). With the key-on try tapping on the relay, it might free it up.

What is recommended for the same problem with a climate control car? I just replaced the little Motorola piece on the control module but the blower is still stuck high with ignition off. I dont see a relay, I'm assuming because it's all inside the board.
