STEP 21. Check the rear power window motor (LH).
(1) Remove the rear power regulator assembly (LH). Refer to

GROUP 42, Door-Door Glass and Regulator

P.42-38

.

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

motor runs freely.

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

YES : Go to Step 22.
NO : Replace the rear power regulator assembly (LH).

Verify that the rear power window sub-switch (LH)
should now work normally.

STEP 22. Check at rear power window sub-switch
connector H-02 in order to check the power window relay
circuit of the power supply to the rear power window
sub-switch (LH).
(1) Disconnect rear power window sub-switch (LH) connector

H-02, and measure at the harness side.

(2) Measure the voltage between terminal 4 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 25.
NO : Go to Step 23.

STEP 23. Check power window relay connector D-219 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is power window relay connector D-219 in good

condition?
YES : Go to Step 24.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the rear power window

sub-switch (LH) should now work normally.

STEP 24. Check the harness wiring between power
window relay connector D-219 (terminal 4) and rear power
window sub-switch (LH) connector H-02 (terminal 4).

NOTE: Also check junction block connector D-208 and inter-
mediate connectors D-125 and F-12. If junction block connec-
tor D-208, intermediate connector D-125 or F-12 is damaged,
repair or replace the connector as described in GROUP 00E,
Harness Connector Inspection

P.00E-2

.

Q: Is the harness wiring between power window relay

connector D-219 (terminal 4) and rear power window
sub-switch (LH) connector H-02 (terminal 4) 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. Verify that
the rear power window sub-switch (LH) should now
work normally.

STEP 25. Check at rear power window sub-switch (LH)
connector H-02 in order to check the ground circuit to the
rear power window sub-switch (LH).
(1) Disconnect rear power window sub-switch (LH) connector

H-02, and measure at the harness side.

(2) Measure the resistance value between terminal 5 and

ground.

• The resistance should measure 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 27.
NO : Go to Step 26.

STEP 26. Check the harness wiring between power
window main switch connector H-05 (terminal 13) and rear
power window sub-switch (LH) connector H-02 (terminal
5).
