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, Rear.

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.
