COMMENTS ON TROUBLE SYMPTOM
If the driver's power window does not work by means of the power window main switch, the power window main switch or the driver's door power window motor may be defective.POSSIBLE CAUSES
- Malfunction of the power window main switch
- Malfunction of the power window motor (front RH) <RH drive vehicles>
- Malfunction of the power window motor (front LH) <LH drive vehicles>
- Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Check the power window main switch.
Q: Is the check result normal?
YES:
Go to Step 2
.NO: Refer to Inspection Procedure D-1 "Power windows do not work at all <except vehicles for Argentina>
."Step 4. Measure the voltage at the E-05 power window main switch connector.
- Disconnect the connector, and measure at the wiring harness side.
- Turn the ignition switch to the ON position.
- Voltage between terminal 13 and body earth
OK: Battery positive voltage
Q: Is the check result normal?
YES:
Go to Step 7.NO: Go to Step 5
.Step 6. Check the wiring harness between C-208 power window relay connector terminal No.4 and E-05 power window main switch connector terminal No.13.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-15, E-29 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 9. Check the wiring harness from E-23 power window motor (front RH) connector terminal Nos.1 and 4 to E-05 power window main switch connector terminal Nos.8 and 9.
NOTE: Prior to the wiring harness inspection, check intermediate connector 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 10. Measure the voltage at the E-05 power window main switch connector.
- Disconnect the connector, and measure at the wiring harness side.
- Turn the ignition switch to the ON position.
- Voltage between terminal 13 and body earth
OK: Battery positive voltage
Q: Is the check result normal?
YES:
Go to Step 13.NO: Go to Step 11
.Step 12. Check the wiring harness between C-208 power window relay connector terminal No.4 and E-05 power window main switch connector terminal No.13.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-118, E-12 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 15. Check the wiring harness from E-13 power window motor (front LH) connector terminal Nos.1 and 4 to E-05 power window main switch connector terminal Nos.8 and 9.
NOTE: Prior to the wiring harness inspection, check intermediate connector E-12, 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.
