Re: Blower motor or Resistor?

Welcome to AF!!

Remove the blower motor and make sure that the motor is working by connecting it to at 12 volt source. Then test the connection to see if there is power coming from the resistor to the motor. It is possible that one or the other may be bad. If that doesn't work you may have to replace the ignition switch that sends power to the resistor. This usually doesn't fail but if no power is going to the resistor then the fan will not work.
