power will be restored when the system voltage rises
above 12.2 volts for 14 seconds and stays there. The
cycle will repeat if the system voltage again drops
below 11.7 volts.
DIAGNOSIS AND TESTING - HEATED SEAT
ELEMENT
Refer to Heated Seat System in this section for
the location of the proper heated seat system diagno-
sis and testing procedures. To check the heated seat
element and sensor circuits, proceed as follows. The
wire harness connectors for the seat cushion heated
seat element and sensor and for the seat back heated
seat element are located under the seat, near the
rear edge of the seat cushion frame. Refer to Wiring
Diagrams for the location of complete heated seat
system wiring diagrams.
NOTE: When checking heated seat elements for
continuity, be certain to move the heating element
being checked. Moving the element, such as siting
in the seat will eliminate the possibility of an inter-
mittent open in the element which would only be
evident if the element was in a certain position.
Failure to check the element in various positions
could result in an incomplete test.
SEAT CUSHION
(1) Disconnect and isolate the battery negative
cable. Disconnect the green 4-way heated seat wire
harness connector. Using an ohmmeter, check for
continuity between pins A and B of the seat cushion
wire harness connector (Fig. 1). There should be con-
tinuity. If OK, test the seat back element as
described below. If not OK, check the green 2-way
seat cushion connector. If OK, replace the faulty seat
cushion cover and element assembly.
SEAT BACK
(1) Disconnect and isolate the battery negative
cable. Disconnect the green 2-way heated seat back
wire harness connector. Using an ohmmeter, check
the resistance between the two pins. There should be
continuity. If OK, test the heated seat control module
as described in this section. If not OK, replace the
faulty seat back cover and element assembly.
REMOVAL
Do not remove the original heating element from
the seat or seat back cushion/trim covers. The origi-
nal element is permanently attached and cannot be
removed without permanent damage. Models with
replaceable heating elements are designed to be
applied directly over the original heating elements.
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the appropriate seat cushion or seat
back trim cover. Refer to the Body section of the ser-
vice manual for the procedures.
(3) Disconnect the inoperative heated seat cushion
or seat back element electrical connectors.
(4) Locate the wires leading from the inoperative
heating element and cut them off flush with the edge
of the original heating element.
INSTALLATION
(1) Peel off the adhesive backing on the back of the
replacement heating element and stick directly on
the foam cushion or on top of original heating ele-
ment.
CAUTION: During the installation of the replace-
ment heating element, be careful not to fold or
crease the element assembly. Folds or creases will
cause premature failure.
(2) Connect the new heating element electrical
connectors (Fig. 2).
(3) Connect the negative battery cable.
(4) Verify heated seat system operation.
(5) Install the appropriate seat cushion or seat
back trim cover. Make certain the seat wire harness
is correctly routed through the seat and seat back.
The excess wire between the cushion and back ele-
ments should be securely tucked between the rear of
the cushion foam and the trim cover.
HEATED SEAT SWITCH
DESCRIPTION
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 (Fig. 3). These knobs have numerals
0-6 to indicate the desired rate of supplemental seat
heating. The instrument panel wire harness connec-
tors 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 ori-
entation.
The heated seat switch cannot be repaired. If the
indicator or back lighting lamps are faulty or dam-
aged, the individual heated seat switch unit must be
replaced.
OPERATION
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 igni-
tion switch is in the On position. The remaining
LED’s illuminate the numbers on the switch, indicat-
ing that the system is on..
