Heater Mat
WARNING: This page is about a different car, the 2016 Ford Transit Connect. However, it is still accessible from the selected car via links, so may be relevant.
The heated seat module is part of the cushion heater mat assembly (includes heated seat module, cushion heater mat and associated wiring) and cannot be serviced separately.
The cushion heater mat is equipped with a temperature sensor (thermistor) which provides feedback to the heated seat module. The minimum/maximum operating range of the temperature sensor is -40 ° C (-39.9 ° F) (269K ohms) to 120 ° C (247.8 ° F) (311 ohms).
