Buick LeSabre blower not working on ac or heater?

A very common solution here is replacement of the blower motor resistor. The resistor when they break do one of two things.
A. work only on high
B. dont work.
This item is located on passanger side under dash and is usually held in with two small bolts on either side with an electrical connector seperating the mounting screws. It is mounted right in the air box.
In some cases if after replacing the resistor,if still the fan is not getting started,then its faulty blower motor itself.
