2004 Crown Vic Heater resistor

I have an 04 Crown victoria and the blower motor for the ac / heat only works on high and low. Does any one know where I can find the resistor on the car to solve this problem? If you know could you share it with me

It is located behind the left rear of the engine bolted to the a/c housing. Look down behind the passenger valve cover and you will see the connector.
