2002 Infiniti I35 AC / heater blower

Test the blower motor resistor this is where it will drop the voltage before it gets to the blower motor-

Thanks , now where would that be. I know just a little about my daugther's car.

Check it -disregard the blower motor resistor don't have one -check and test the fan controller amplifier behind right side of dash on blower and cooling unit-

do you have a picture of this amp. Because I did take apart the glove compartment and pulled the blower out. would this amp be inside the blower hole.
