Instrument Panel, Gauges and Warning Indicators: Description and Operation

Instrument Cluster Assembly
The instrument cluster assembly houses driver-operated switches and controls. An analog electric speedometer, stepper motor-driven odometer, trip meter, analog fuel gauge, temperature gauge, and information/warning center are located in the cluster. Center information/warnings include:
a. Engine oil pressure warning
b. ABS warning
c. Check engine warning
d. Rear window defroster indicator
e. Brake warning
f. Charge warning
g. Seat belt warning
h. High beam indicator
i. Door open warning
j. Parking brake indicator
k. Four-wheel drive indicator
l. Accessory (ACC) indicator
m. Low fuel warning
n. Hazard warning
o. Turn signal indicators




Instrument cluster electrical connectors are located at the rear of the assembly. When the assembly is removed, instrument panel electrical harness connectors are disconnected. A printed circuit is mounted on the back of the instrument cluster. It transfers electrical power to the cluster. Bulb holders are removed at the rear of the instrument cluster. Instruments are removed from the cluster after the cluster has been removed and the bezel/lens has been removed from the cluster case. Instrument cluster trim electrical connectors are located at the rear of trim switches and are disconnected when the cluster trim is removed. When the ignition is in the ON position, instrument and switch lights are checked. If any light is inoperative, a replacement of the failed bulb should be made.
