Seat Temperature Switch: Description and Operation
HEATED SEAT SWITCHJR Heated Seat Switch:
The heated seat switch used on vehicles with this option is mounted in the center console. The switch is snapped into a mounting hole in a center console trim panel. The heated seat switch incorporates two rotary knobs, one for the driver and one for the front seat passenger. These knobs have numerals 0-6 to indicate the desired rate of supplemental seat heating. The instrument panel wire harness connectors for the heated seat switch is keyed to match the connector receptacle on the switch so that the heated seat switch can only be connected in the proper orientation.
The heated seat switch cannot be repaired. If the indicator or back lighting lamps are faulty or damaged, the individual heated seat switch unit must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit when the ignition switch is in the On position. The two six-position rotating-type switches provide a hard-wired voltage signal to the heated seat module to power the heated seat element of the selected seat and maintain the requested temperature setting.
There are three Light Emitting Diodes (LED's) in the heated seat switch. The first LED illuminates the heated seat symbol on the switch anytime the ignition switch is in the On position. The remaining LED's illuminate the numbers on the switch, indicating that the system is on..
