COMMENTS ON TROUBLE SYMPTOM
If the front passenger's or rear power window does not work by means of the respective
power window sub switch, the power window sub switch or the power window motor may be defective.POSSIBLE CAUSES
- Malfunction of the power window sub switch (front LH), power window sub switch (rear RH) or power window sub switch (rear LH)
- Malfunction of the power window sub switch (front LH), power window motor (rear RH) or power window motor (rear LH)
- Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 7. Measure the voltage at E-31 power window sub switch (front
LH) connector.
- Disconnect the connector, and measure at the wiring harness side.

(rear RH) connector terminal No.5 to C-208 power window connector terminal No.4.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-13, D-01, E-27
and junction block connector C-203, and repair if necessary.
- Check the power supply line for open circuit.
Q: Is the check result normal?
YES:
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope
with Intermittent Malfunction ).NO: Repair the wiring harness.
Step 21. Check the wiring harness from E-19 power window motor (rear
RH) connector terminal Nos.1 and 2 to E-21 power window sub switch (rear RH) connector terminal
Nos.7 and 6.
NOTE: Prior to the wiring harness inspection, check intermediate connector E-27, and repair
if necessary.
- Check the power window operation line for open circuit.
Q: Is the check result normal?
YES:
Go to Step 22.NO: Repair the wiring harness.
Step 22. Check the wiring harness from E-21 power window sub switch
(rear LH) connector terminals 4 and 8 to E-05 power window main switch connector terminals 14 and
6.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-13, C-15, D-01,
E-27 and E-29, and repair if necessary.
- Check the power window operation line for open circuit.
Q: Is the check result normal?
YES:
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope
with Intermittent Malfunction ).NO: Repair the wiring harness.
Step 25. Measure the voltage at E-01 power window sub switch (rear
LH) connector.
- Disconnect the connector, and measure at the wiring harness side.
- Turn the ignition switch to the ON position.
- Voltage between terminal 5 and body earth
OK: Battery positive voltage
Q: Is the check result normal?
YES:
Go to Step 28.NO: Go to Step 26
.Step 27. Check the wiring harness from E-01 power window sub switch
(rear LH) connector terminal No.5 to C-208 power window connector terminal No.4.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-117, D-25, E-09
and junction block connector C-203, and repair if necessary.
- Check the power supply line for open circuit.
