HEATED SEAT SYSTEM
DESCRIPTION
Individually controlled, electrically heated front
seats are available factory-installed optional equip-
ment on this model. Vehicles with this option can be
visually identified by the two separate heated seat
switches mounted on each of the seat cushion side
shields. The heated seat system allows the front seat
driver and passenger to select from two different lev-
els of supplemental electrical seat heating, or no seat
heating to suit their individual comfort requirements.
The heated seat system for this vehicle includes the
following major components, which are described in
further detail later in this section:
• Heated Seat Elements - Two heated seat ele-
ments are used per vehicle, one for each front seat.
The heated seat elements are integral to the front
seat and seat back cushions. Refer to the description
of the heated seat elements later in this section for
additional information.
• Heated Seat Modules - Two heated seat mod-
ules are used per vehicle. One module is mounted to
each of the power seat cushion pans, under the for-
ward edge of each front seat. Refer to the description
of the heated seat module in the electronic control
modules section of the service manual for additional
information.
• Heated Seat Relay - One heated seat relay is
used per vehicle. The relay is located in the instru-

instrument panel.
• Heated Seat Sensors - Two heated seat sen-
sors are used per vehicle, one for each front seat. The
heated seat sensors are integral to each of the heated
seat cushions.
• Heated Seat Switch - Two heated seat
switches are used per vehicle, one for the driver and
one for the passenger side front seats. The switches
are mounted to each of the front seat cushion side
shields. Refer to the description of the heated seat
switch later in this section for additional information.
Hard wired circuitry connects the heated seat sys-
tem components to each other through the electrical
system of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system and to the
heated seat system components through the use of a
combination of soldered splices, splice block connec-
tors and many different types of wire harness termi-
nal
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, further details on wire
harness routing and retention, as well as pin-out and
location views for the various wire harness connec-
tors, splices and grounds.
