Many dealers have the part in stock. The blower motor resistor or control module replacement is not very expensive. For example, one of our colleagues had a problem with his 2011 Ford Escape: the fan only worked at the speed 4. The Ford dealership charged $60 to diagnose and $152 to replace the resistor. Checked the condition of the fan by connecting directly to a 12 volt supply and it works. Checked the resistor and the connector on the resistor it is getting power and the control cable seems to have current. Swapped the resistor in case part of the circuit was blown, no difference.2003 FORD EXPEDITION - CLIMATE CONTROL PROBLEM - A/C only blows cold air on the "Max A/C" setting.
