Seat Heater Switch: Description and Operation
Heated Seat Switch - Description
Rear
REAR
The heated seat switches (1) for the 2nd row seats are located in the rear center floor console (2). These switches allow the 2nd row seat passengers to
select from two different levels of electrical seat heating (HI/LO). Amber Light Emitting Diodes (LEDS) in the top portion of each switch indicate the
level of heat in use: Two LEDs are illuminated for high, one for low, and none for off. Pressing the switch once will select high-level heating. Pressing
the switch a second time will select low-level heating. Pressing the switch a third time will shut the heating elements off. The 2nd row heated seat
switches are available individually for service. If the switches are inoperative or damaged in any way they should be replaced, See: Service and
Repair/Heated Seat Switch - Removal.
The two momentary, push button-type heated seat switches provide a hardwired resistance signal to the Instrument Cluster (also known as the Cab
Compartment Node/CCN). The instrument cluster then sends a message via the Controller Area Network (CAN) data bus network to the heated seat
module, signaling the module to energize the heating element for the selected seat. Light Emitting Diodes (LED) in each switch indicate the level of heat
in use. The switch LEDs are controlled by the instrument cluster.
The two LED indicator lamps and the incandescent bulb in each heated seat switch cannot be repaired. If the indicator lamps or back lighting bulb are
inoperative or damaged, the individual heated seat switch must be replaced.

The Heated Seat Switches(1) are momentary contact push button switches mounted in the instrument panel center bezel that operate the heated seat
system. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps, which indicate the selected level (Low or High) of the seat heater.
Pressing the switch initiates heat. Heat remains on until switched off or until the ignition is turned off. If switched off by the ignition, a switch must be
pressed to restart heating.
