Driver Heated Seat Switch: Description
The heated seat switches are located on the outboard seat cushion side shield of the driver and passenger front seats.
The momentary, bidirectional rocker-type heated seat switch (Fig 1 ) provides a resistor-multiplexed signal to the Memory Heated Seat/Mirror Module (MHSMM) via a hard-wired mux circuit. Each switch has a center neutral position and momentary Low and High positions so that both the driver and the front seat passenger can select a preferred level of seat heating. Each heated seat switch contains two Light-Emitting Diode (LED) indicator lamps, which indicate the selected mode of the seat heater (HI/LO). Each switch also contains a incandescent bulb, which provides dimmer controlled back lighting of the switch when the headlamps or park lamps are on.
The two LED indicator lamps and the incandescent bulb in each heated seat switch cannot be repaired or replaced. If the LED indicator lamps or back lighting bulb are faulty or damaged, the complete heated seat switch must be replaced.
