DESCRIPTION AND OPERATION
INSTRUMENT PANEL SYSTEM
DESCRIPTION
The instrument panel serves as the command cen-
ter of the vehicle, which necessarily makes it a very
complex unit. The instrument panel is designed to
house the controls and monitors for standard and
optional powertrains, climate control systems, audio
systems, lighting systems, safety systems and many
other comfort or convenience items. The instrument
panel is also designed so that all of the various con-
trols can be safely reached and the monitors can be
easily viewed by the vehicle operator when driving,
while still allowing relative ease of access to each of
these items for service. See the owner's manual in
the vehicle glove box for more information on the fea-
tures, use and operation of all of the instrument
panel components and systems.
This group is responsible for covering service infor-
mation for the vehicle instrument panel systems.
However, complete service information coverage for
all of the systems and components housed in the
instrument panel in a single section of the service
manual would not be practical. Therefore, the service
information for any component will be found in the
group designated to cover the vehicle system that the
component belongs to, even though the component is

INSTRUMENT PANEL
DESCRIPTION
Modular instrument panel construction allows all
of the gauges and controls to be serviced from the
front of the panel. In addition, most of the instru-
ment panel electrical or heating and air conditioning
components can be accessed without complete instru-
ment panel removal. If necessary, the instrument
panel can be removed from the vehicle as an assem-
bly.
Removal of the steering column opening cover and
the knee blocker provides access to the steering col-
umn mounts, the steering column wiring, the gear-
shift interlock mechanism, the headlamp switch, and
much of the instrument panel wiring. Removal of the
glove box provides access to the fuseblock module,
additional instrument panel wiring, and many of the
heating and air conditioning components.
Removal of the instrument cluster bezel allows
access to the cluster assembly. Removal of the cluster
