AC AND HEATER FAN NOT WORKING on 2005 Mercury Grand Marquis

DOES NOT WORK ON AC OR HEAT

Asked by for the 2005 Mercury Grand Marquis
Most likely it is the blower resistor. I have a 2005 Grand Marquis, the resistor has went out twice. It is recommended not to run the fan on the lowest speed as the fan is used to cool the resistor.
