Howard (PA27) this is from the Ford Mach-E repair manual on the operation of the Heated Seats:
Heated Seat Operation:
This system allows on demand, independent, electrical heating of each front seat.
The heated seat system consists of the following components:
● Seat cushion heater mat
● Seat backrest heater mat
● HVAC module
● Touchscreen (contains the heated seat buttons)
The driver and passenger heated seat control buttons and indicators are located on the touchscreen. The heated seat system functions independently from the vehicle's climate control system (except when the seat(s) are in AUTO mode). Each time the heated seat button is pressed, the system will cycle through the following modes: AUTO, HIGH (3 indicators), MED (2 indicators), LOW (1 indicator) then OFF (no indicators).
When activated, the HVAC module supplies voltage to the selected seat heater circuit. Each seat cushion heater mat and backrest heater mat is connected in a series circuit to the HVAC module and powered by the output circuit for that seat. The HVAC module monitors inputs from a temperature sensor located in each seat cushion heater mat, and maintains seat temperature by cycling the heater circuits on/off. The heated seat remains on until the heated seat switch button is pressed to cycle the HVAC module off or the ignition is cycled OFF.
When a seat is in AUTO mode, the temperature of the seat is automatically raised or lowered based on the current termperature control settings on the HVAC climate settings and cabin conditions. The applicable heated seat button indicators will illuminate depending on the intensity of heat that is currently being commanded by the HVAC system.
Remote Start Climate Operation:
Different climate control modes/preferences can be selected when the vehicle is started using the remote start feature. This can be accessed through the message center. For additional information on how to set the remote start preferences, refer to the Owner's Literature. When the driver seat and/or passenger seat is set to AUTO mode, the driver/passenger heated seat activates in full heat mode when the outside temperature is less than 0° C (32° F) any time the vehicle is started using the remote start feature. No heated seat adjustments are recognized during remote start operation.
