SRS MAII{ HAR'{ESS
The rear window defogger is controlled by the integrated control unit, Pushing the defogger switch in the instrument
panel it sends a signal to the defogger time. in the integrated control unit, and the detogger stays on tor 25 minutes
or until the ignition switch is turned off. The indicator light in the switch comes on when the deJogger works.

Rear Window Defogger
Function Test
CAUTION: Be carelul not to scratch 01 damago ths
defogger wires with th€ tsster probe.
1 . Check for voltage between the positive terminal and
body ground with the ignition switch and the delog-
ger switch ON. There should be battery voltage.
a lf there is no voltage, check for
- laulty detogger relay.- faulty defogger switch.- faulty integrated control unit.- an open in the BLK/GRN wire
a lJ there is baftery voltage, go to step 2.
NEGATIVE TERMIiIALPOSITIVE TERMINAL
Turn the rear window detogger switch OFF, Check
for continuity between the negative terminal and
body ground.
a It there is no continuity, check to. an open in the
defogger ground wire.
a ll there is continuity, go to step 3.
Touch the voltmeter positive lead to the halfway
point of each defogger wire, and the negative lead
to the negative terminal.
There should be apptoximately 6 V with the ignition
switch and defogger switch ON.
a lf the voltage is as specified, the defogger wire
is OK.
a lf the voltage is not as specified. repai, the defog-
ger wire:
lf it is more than 6 V, look for the damage on
the negative half on the grid.
- lf it is less than 6 V. iook for the damage on
the positive half of the grid.
Defogger Wires Repair
NOTE: To make an eftective repair. the broken section
must be no longer than one inch.
1 . Lightly rub the area around the break with line steel
wool, then clean it with alcohol.
2. Carefullv mask above and below the broken portion
of the defogger wire with cellophane tape.
Using a small brush, apply a heavy coat of silver con-
ductive paint extending about 3 mm ( 1/8 inl on both
sides of the break. Allow 30 minutes to dry.
NOTE: Thoroughly mix the paint before use.
Check for continuity in the repaired wire.
Apply a second coat of paint in the same way.

a ll there is no continuity, check for- an ooen in the BLK wire.- poor ground (G201 , G4Ol ).
a lf there is continuity, go to step 4.
Check tor voltage between the No. 4 terminal ( + )
and No. 2 terminsl { - ) with the ignition switch ON
{ll). There should be battery voltage.
a lf there is no baftery voltage, check tot- blown No. 1 (3o Al or No. 14 {20 A) fuse in
the under-dash tuse/relay box.- an open in the wires (GRN/BLK, GRN, WHT)
or loose terminals.- faulty moonroof relay.
a lf there is battery voltage, go to step 5.
Connect the No. 4 terminal to the No. 3 terminal,
and the No. 1 terminal to the No, 2 terminal with jum-
per wires. The moonroot should open when the ig-
nition switch is turned ON (ll).
lf the moonroof ooens, check the moonroof
switch,
ll it doesn't open, remove the headlinet and check
the motor.

NOTE; Check the No. 13 (7.5 A) tuse in the under-dash
fuse/relay box before testing.
Ono or both inop€rativa:
1. Check for voltage between the BLKIrEL terminal 8nd

a It there is battery voltage, go to step 2.
2. Check for continuity between the BLK terminal and

Loft mirror inopsrative:
Connect the BLK/YEL terminal of the 10-P connector to
the YEL/RED1 terminal and the YEL/WHT (or YEL/BLKr)
terminal to body ground with jumper wires.
The left mirror should tilt down (or swing leftl when you
turn on the ignition switch.
a lf the mirror does not tilt down (or does not swing leftl,
check Jor an open in the YEL/WHT (or YEL/BLK1)
wire between the left miffor and the switch. It the wir€
is OK, check the left mirror actuator.
a lf the mirro. neither tilts down nor swings left, repair
the YEL/RED1 wire between the left mirror and the
switch.
a lf the mirror operates properly, check the mirror
swatch.
Right mirror inoporative:
Connect the BLK/YEL terminal of the 1O-P connector to
th€ BLU/WHT terminal and the YEL/WHT {or BLU/BLK)
terminal to body ground with iumper wires.
The right mirror should tilt down (or swing left) when you
turn on the ignition switch.
a lf the mirror does not tilt down (or does not swing left),
remove the right door panel and check for an open in
the YELMHT (or BLU/BLK) wire between the right mir-
ror and the switch. lf the wire is OK. check the right
mtrror actualor.
a ll the mirror neither tilts down nor swings lelt, repair
the BLUMHT wire between the right mirror and the
