* PLEASE READ THIS FIRST *
WARNING: Vehicles are equipped with a driver-side air bag; use extreme
caution while working around steering column. To disable air
bag system, ensure ignition switch is in LOCK position and
negative battery cable is disconnected and shielded for at
least 90 seconds before attempting any repair. DO NOT apply
electrical power to any instrument panel connector without
disconnecting air bag control unit. Information labels are
attached to air bag components. Follow all notices on labels.
Use only DVOM (volt/ohmmeter) with minimum of 10-k/ohm
impedance to check ANY circuit.
DESCRIPTION & OPERATION
GAUGES
Standard instrument clusters contain fuel and temperature
gauges with telltale warning lights. Some optional instrument panels
are equipped with a tachometer, oil pressure gauge and voltmeter.
Gauge internal operating components use either a 2-terminal bimetallic
strip type, or a 3-terminal coil type. The 2-terminal type gauges are
generally used on clusters without tachometers.
SWITCHES
All models contain hazard warning switch and cruise control
main ON/OFF switch on instrument panel. All models use a combination
switch for headlight, turn signal, wiper/washer, and cruise control
switches. Combination switch is mounted on steering column. For
testing and/or removal and installation procedures for combination
switch components, see the STEERING COLUMN SWITCHES article in the
ACCESSORIES/SAFETY EQUIPMENT section.
TESTING - GAUGES
FUEL GAUGE & WARNING LIGHT
Fuel Gauge & Wiring Harness Operational Test
1) Unplug fuel tank sending unit connector. Turn ignition on.
If fuel gauge indicates EMPTY, go to next step. If fuel gauge does not
indicate EMPTY, repair short circuit in wiring harness. See wiring
diagram in WIRING DIAGRAMS.
2) Connect a 12-volt, 3.4-watt test light between appropriate
terminals of sending unit wiring harness connector. See FUEL GAUGE &
HARNESS TEST table. See Fig. 1.
3) With ignition on, test light should flash and gauge needle
should move toward FULL. If test light does not flash and gauge needle
does not move, check wiring harness for open circuit. Repair or
replace as necessary. If wiring harness checks good, replace fuel
gauge.
