using ohmmeter. Continuity should be present between terminals No. 1
and 4, and terminals No. 5 and 6. Turn defogger switch to ON position.
Continuity should exist between terminals No. 3 and 2, 5 and 6, and 1
and 4. See Fig. 1.
Montero
Turn defogger switch to OFF position. Check switch continuity
using ohmmeter. Continuity should be present between terminals No. 5
and 6, and terminals No. 1 and 2. Turn defogger switch to ON position.
Continuity should exist between terminals No. 3 and 4, 5 and 6, and 1
and 2. See Fig. 1.
Stealth & 3000GT
Remove defogger switch assembly from instrument cluster
bezel. With defogger switch in OFF position, check switch continuity
using ohmmeter. Continuity should exist between terminals No. 3 and 4.
With defogger switch in ON position, continuity should exist between
terminals No. 1 and 2, 1 and 6, and 3 and 4. See Fig. 1.

DEFOGGER RELAY TEST

Colt, Colt 200, Mirage & Summit
Remove defogger relay located to the right of fuse block.
Ground relay terminal No. 4, and apply battery voltage to terminal No.
2. Check relay continuity using ohmmeter. Continuity should exist
between terminals No. 1 and 3. With voltage disconnected, continuity
should not be present between terminals No. 1 and 3. Ensure continuity
is present between terminals No. 2 and 4. See Fig. 2.
Colt Vista, Eclipse, Stealth & 3000GT
Remove defogger relay located on left center of firewall.
Ground relay terminal No. 4, and apply battery voltage to relay
terminal No. 3. Check relay continuity using ohmmeter. Ensure
continuity exists between terminals No. 1 and 2. With voltage
disconnected, continuity should not exist between terminals No. 1 and
2. Continuity should exist between terminals No. 3 and 4. See Fig. 2.
Galant
Remove defogger relay located in right front corner of engine
compartment. Ground relay terminal No. 1, and apply battery voltage to
terminal No. 3. Check relay continuity using ohmmeter. Continuity
should exist between terminals No. 4 and 5. See Fig. 2. With voltage
disconnected, continuity should not exist between terminals No. 4 and
5. Ensure continuity exists between terminals No. 1 and 3. See Fig. 2.

DEFOGGER TIMER TEST

Colt, Colt 200, Mirage & Summit
Remove defogger timer from junction block under left side of
instrument panel. Connect a battery and test light to defogger timer
terminals. See Fig. 3. Apply battery voltage to terminal No. 7 for 5-7
seconds. Ensure test light illuminates for approximately 10 seconds.
Reapply battery voltage to terminal No. 7. Test light should go off
when voltage is applied again.
Colt Vista
With ignition switch in ON position, apply battery voltage to
terminal No. 2 of defogger timer. Timer should operate for
approximately 11 seconds then stop. See Fig. 3.
Eclipse & Galant
Remove defogger timer from interior relay block. Connect
battery voltage and test light to timer. See Fig. 3. Ensure test light
illuminates for approximately 11 seconds when battery voltage is
applied to terminal No. 4. Reapply battery voltage to terminal No. 4
and observe test light. Test light should go off.

GRID TEST
1) Start engine and operate at 2000 RPM. Ensure battery is
fully charged. Turn defogger switch to ON position. Using a voltmeter,
check voltage at center section of each grid wire. If voltage is
approximately 6 volts, grid wire is okay. If voltage is approximately
12 volts, an open is present in the negative circuit. Move probe
slowly toward the negative terminal to determine location of open
circuit.
2) If voltage is zero volt, an open is present in the
positive circuit. Move probe slowly toward the positive terminal to
