Blower motor resistor

Have no speeds on blower motor on 1974 Satellite...anyone know part number and source for resistor.....internet search shows no results except for Fury model...help.

Most of those were the same.Just make sure the switch is powering the resistor and that you have power and ground to the motor.Rocky

how do you know its the resistor? most cars when they go bad the motor only blows on one speed. i would do a voltage drop test to confirm its bad before replacing it.
