I have a 2009 f150 fx4 it will not blow cold air or heat on any setting. i have replaced the resistor and it stopped working again if i smack the black box the resistor is in it will work again. My question is where is the blower motor and how hard of a job is it to change. I just ordered the motor.

thank you
Brian
