@puneetsingh your Lincoln does not have a Blower Motor Resistor in the conventional sense. It uses a blower motor speed control module . It's located under the hood, mounted to the A/C evaporator housing on the passenger's side rear of the engine compartment.

The video link from @jimfixer shows essentially the same information, just a different model bu same location same setup.
