2015-2016 Expedition/Navigator – Blower Motor Fluctuation When Coolant Temperature Is Below 122F (50C)
Some 2015-2016 Expedition/Navigator vehicles may exhibit noticeable blower motor speed fluctuations when the engine is cold or as the engine is warming up to normal operating temperature.
This is most likely to occur when the coolant temperature is below 122 degrees Fahrenheit (50 degrees Celsius.)
Reprogram the Heating, Ventilation, Air Conditioning Module (HVAC) to the latest calibration using IDS release 105.01 or higher.
Make sure you are connected to the internet when entering module programming to obtain the latest updates.
