Heater Mat
WARNING: This page is about a different car, the 2018 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
The cushion heater mats are each equipped with a temperature sensor (thermistor) which provides feedback to the FCIM (heated seats only) or SCME (climate controlled seats). The heater mats are serviced by installing a new backrest/cushion foam. The cushion and backrest heater mats are connected in series.
