Some 2010-2019 Lincoln MKT vehicles may exhibit inoperative or intermittent HVAC blower motor function at various fan speed settings.
This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the casual part, replacement of the electrical connector pigtail harness 14S411 to the blower motor speed control is also recommended to avoid repeat repairs.
Refer to Wiring Diagram, calls 54/55 to obtain the service pigtail connector part number.
