Ford Police Interceptor Gets Hot Under the Collar
Some 2013-2019 Ford Police Interceptor Utility/Sedan vehicles may exhibit an 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 causal part, replacement of the electrical connector pigtail harness (14S411) to the blower motor speed control is also recommended to avoid repeat repairs.
Refer to the wiring diagram, Cells 54/55 to obtain the service pigtail connector part number.
