Seat Temperature Switch: Description and Operation
Heated Seat Switch Location:
The heated seat switch assembly is located on the center console where the ashtray is normally located. The two momentary, two-directional rocker switches, one switch for each front seat, provide a resistor-multiplexed signal to the Seat Heat Interface Module (SHIM). Each switch has center NEUTRAL, and momentary LO and HI positions so that both the driver and the front seat passenger can select a preferred seat heating mode.
Each switch has two telltales (LED's) which indicate the mode of the heater of the respective seat.
The switches also have LED's which provide back-lighting when the ignition switch is in the ON position. The LED's cannot be repaired. If the LED is faulty, the individual switch must be replaced.
