Seat Temperature Thermostat: Description and Operation

SYSTEM OPERATION
HEATED SEAT ELEMENT AND SENSOR
Two heated seat elements are used in both of the front seats, one for the seat cushion and the other for the seat back. The two elements for each seat are connected in series to the MHSMM.

The temperature sensor is a Negative Temperature Coefficient (NTC) thermistor. One temperature sensor is used for each set, and it is integrated into the seat cushion heating element

The heating elements are sewn into the seat cushion cover and seat back cover assemblies, which are serviced individually. The heating elements and temperature sensor cannot be repaired, and if faulty or damaged, the affected seat cover must be replaced.
