Heated Seats

Voltage is applied at all times to the Heated Seat Control Module through the HEATED SEAT Fuse and through the IGN 3 Fuse with the ignition switch in "RUN." when the Seat Heat Switch is pressed on the Seat/Lock Switch, the Heated Seat Control Module Seat Heat Switch input terminal is momentarily grounded. This causes the Heated Seat Control Module to apply voltage to the front seat heaters. The Heated Seat Control Module monitors the seat surface temperature through a thermistor and maintains a pre-determined temperature. With the Heated Seat off and the Seat Heat Switch is pressed once, the Heated Seat Control Module will set the Heated Seat temperature to HI. When pressed again, the Heated Seat temperature is then set to LO. After the third press of the Seat Heat Switch, the Heated Seat Control Module stops applying voltage to the front seat heaters. The module will also turn off the heated seats whenever the ignition switch has been turned off.
