NOTE: Also check junction block connector C-215 and inter-
mediate connector C-26. If junction block connector C-215 or
intermediate connectors C-26 is damaged, repair or replace the
damaged component(s) as described in GROUP 00E, Harness
Connector Inspection

P.00E-2

.

Q: Is the wiring harness between power window relay

connector C-203 (terminal 4) and front power window
sub switch connector E-12 (terminal 6) in good
condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
front power window sub switch is operated, the front
power window (LH) should raise and lower normally.

STEP 11. Check the ground circuit to the front power
window sub switch. Measure the resistance at front power
window sub switch connector E-12.
(1) Disconnect front power window sub switch connector E-12

and measure the resistance available at the wiring harness
side of the connector.

(2) Measure the resistance value between terminal 5 and

ground, and also between terminal 8 and ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 13.
NO : Go to Step 12.

STEP 12. Check the wiring harness between power
window main switch connector E-04 (terminals 7 and 9)
and front power window sub switch connector E-12
(terminals 8 and 5).

NOTE: Also check intermediate connectors C-12 and C-26. If
intermediate connector C-12 or C-26 is damaged, repair or
replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between power window main

switch connector E-04 (terminals 7 and 9) and front
power window sub switch connector E-12 (terminals 8
and 5) in good condition?
YES : Replace the power window main switch. When the

front power window sub switch (LH) is operated, the
front power window (LH) should raise and lower
normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
front power window sub switch (LH) is operated, the
front power window (LH) should raise and lower
normally.

STEP 13. Check the wiring harness between front power
window sub switch connector E-12 (terminals 4 and 7) and
front power window regulator motor (LH) connector E-13
(terminals 1 and 2).
Q: Is the wiring harness between front power window sub

switch connector E-12 (terminals 4 and 7) and front
power window regulator motor (LH) connector E-13
(terminals 1 and 2) in good condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
front power window sub switch (LH) is operated, the
front power window (LH) should raise and lower
normally.

STEP 14. Check rear power window sub switch (LH)
connector E-17 and rear power window regulator motor
(LH) connector E-16 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Are rear power window sub switch (LH) connector E-17

and rear power window regulator motor (LH) connector
E-16 in good condition?
YES : Go to Step 15.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. When the rear power window sub switch

(LH) is operated, the rear power window (LH) should
raise and lower normally.

STEP 15. Check the rear power window sub switch (LH) for
continuity.
(1) Remove the rear power window sub switch (LH). Refer to

GROUP 42, Door, Door Glass and Regulator

P.42-39

.

(2) Check continuity when the rear power window sub switch

(LH) is operated to "UP" or "DOWN" position.

Q: Is the rear power window sub switch (LH) normal?

YES : Go to Step 16.
NO : Replace the rear power window sub switch (LH).

When the rear power window sub switch (LH) is
operated, the rear power window (LH) should raise
and lower normally.

STEP 16. Check the rear power window regulator motor
(LH).
(1) Remove the rear power window regulator assembly (LH).

Refer to GROUP 42, Door, Door Glass and Regulator

P.42-39

.

(2) Connect a battery to the motor terminal, and check that the

motor runs freely.

Q: Is the rear power window regulator motor (LH) normal?

YES : Go to Step 17.
NO : Replace the rear power regulator assembly (LH).

When the rear power window sub switch (LH) is
operated, the rear power window (LH) should raise
and lower normally.

STEP 17. Check the battery power supply circuit to the rear
power window sub switch (LH). Measure the voltage at rear
power window sub switch (LH) connector E-17.
(1) Disconnect rear power window sub switch (LH) connector

E-17 and measure the voltage available at the wiring
harness side of the connector.

(2) Measure the voltage between terminal 6 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 20.
NO : Go to Step 18.
