Circuit Operation
When the starter switch is in ON or START, fuse C-2
applies battery voltage to the driver’s and right front
seat heater switches.
Heat Operation
When the driver’s or right front seat heater switch is
moved to HEAT, battery voltage is applied through the
circuit breakers in the respective seat cushion to both
the seat cushion and seat back heating elements. The
seat back is grounded through the seat heater switch to
B-26 while the seat cushion is grounded directly to
B-26. With battery voltage applied to the heating ele-
ments in this manner, they draw the maximum current
causing them to heat up quickly and to a high tempera-
ture. When the temperature becomes too high the cir-
cuit breakers in the seat cushion open, removing the
voltage to the circuit. When the temperature falls to a
safe temperature, the circuit breakers close, supplying
voltage to the circuit.
Keep Operation
When the driver’s or right front seat heater switch is
moved to KEEP, battery voltage is applied through the
respective seat cushion heating element to the re-
spective seat cushion heating element. The respec-
tive seat cushion is grounded directly to B-26. With
battery voltage applied to the heating elements in this
manner, they draw less current, and do not reach as
high of a temperature as in the HEAT position.

Circuit Operation
With the starter switch in ON or START, voltage is
applied through fuse C-4 to the mirror defogger switch.
With the mirror defogger switch in ON, voltage is
applied to the left and right door mirror defoggers and
the defogger indicator light. The defogger on indicator
lights up and the left and right door mirror defoggers
heat the mirror surfaces to remove any fog.
