and fuse block and a good ground. There should be
continuity. If OK, go to Step 9. If not OK, repair the
open ground circuit to ground as required.
(9) Disconnect the instrument panel wire harness
connector from the multi-function switch connector
receptacle. Check for continuity between the hazard
signal circuit cavities for the combination flasher in
the relay and fuse block and in the instrument panel
wire harness connector for the multi-function switch.
There should be continuity. If OK, go to Step 10. If
not OK, repair the open hazard signal circuit as
required.
(10) Check for continuity between the turn signal
circuit cavities for the combination flasher in the
relay and fuse block and in the instrument panel
wire harness connector for the multi-function switch.
There should be continuity. If OK, refer to Turn Sig-
nal Switch and Hazard Warning Switch in the
Diagnosis and Testing section of this group. If not
OK, repair the open turn signal circuit as required.
TURN SIGNAL SWITCH AND HAZARD
WARNING SWITCH
The turn signal switch and the hazard warning
switch are integral to the multi-function switch.
Refer to Turn Signal and Hazard Warning Sys-
tems in the Diagnosis and Testing section of this
group before testing the multi-function switch. For
complete circuit diagrams, refer to Turn Signals in
the Contents of Group 8W - Wiring Diagrams.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, REFER TO GROUP 8M - PASSIVE
RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, OR
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
(1) Disconnect and isolate the battery negative
cable. Disconnect the instrument panel wire harness
connector from the multi-function switch connector
receptacle.
(2) Using an ohmmeter, perform the switch conti-
nuity checks at the connector receptacle terminals as
shown in the Multi-Function Switch Continuity chart
(Fig. 3).
(3) If the turn signal switch or hazard warning
switch fails any of the continuity checks, replace the
faulty multi-function switch assembly as required. If
the switch circuits are OK, repair the lighting cir-
cuits as required.

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, REFER TO GROUP 8M - PASSIVE
RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, OR
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the steering column opening cover
from the instrument panel. Refer to Steering Col-
umn Opening Cover in the Removal and Installa-
tion section of Group 8E - Instrument Panel Systems
for the procedures.
(3) Reach through the outboard side of the steer-
ing column opening in the instrument panel to access
the relay and fuse block on the back of the junction
block (Fig. 4).
(4) Refer to Fuse/Fuse Block in the Contents of
Group 8W - Wiring Diagrams for combination flasher
identification and location.
(5) Remove the combination flasher from the relay
and fuse block.
INSTALLATION
(1) Refer to Fuse/Fuse Block in the Contents of
Group 8W - Wiring Diagrams for proper combination
flasher location.
(2) Position the combination flasher in the proper
receptacle in the relay and fuse block.
(3) Align the combination flasher terminals with
the terminal cavities in the relay and fuse block
receptacle.
(4) Push in firmly on the combination flasher until
the terminals are fully seated in the terminal cavities
in the relay and fuse block receptacle.
(5) Install the steering column opening cover onto
the instrument panel. Refer to Steering Column
Opening Cover in the Removal and Installation sec-
tion of Group 8E - Instrument Panel Systems for the
procedures.
(6) Reconnect the battery negative cable.
