Diagnostic procedure

STEP

INSPECTION

ACTION
1
•  Switch the ignition to ON.
•  Does the LED on the power window main switch illuminate?
Yes
Go to Step 6.
No
Go to the next step.
2
•  Operate all power windows other than the driver’s window using the power window main switch.
•  Does the power window operate properly?
Yes
Go to the next step.
No
Inspect for an open or short circuit in the following wiring harnesses. Inspect the connector connections (damage/pulled-out pins, corrosion):
•  P.WIND 30 A fuse—Power window main switch terminal 1M
•  Power window main switch terminal 1B—ground.
Repair or replace if necessary.
3
•  Is the P.WIND 25 A fuse normal?
Yes
Go to Step 5.
No
Inspect the following:
•  Short circuit in B+ power supply wiring harness
•  Short circuit in power window motor
Repair or replace if necessary.
Replace with the appropriate standard fuse.
Then, go to the next step.
4
•  Initialize the power window system.
•  Operate the power window system.
•  Do the power windows operate properly?
Yes
Troubleshooting is completed.
No
Re-confirm the symptom and go to Step 1.
5
•  Measure the voltage at the power window main switch terminal 1N.
•  Is the voltage B+?
Yes
Replace the power window main switch.
(See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)
No
Inspect for an open or short circuit in the power window main switch wiring harness (battery power supply).
Inspect the power window main switch connector connection. (damage/pulled-out pins, corrosion)
Repair or replace if necessary.
6
•  Measure the voltage at the power window main switch. (power window motor output terminal) while operating the power window using the power window main switch.
•  Is the voltage B+?
(Open: terminal 1L/ close: terminal 1J)
Yes
Go to the next step.
No
Replace the power window main switch.
(See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)
7
•  Measure the voltage at the power window motor. (battery power supply terminal) while operating the power window using the power window motor.
•  Is the voltage B+?
(Open: terminal F/ close: terminal E)
Yes
Go to the next step.
No
Inspect for an open or short circuit in the wiring harness between the power window main switch and the power window motor.
Inspect the power window main switch and power window motor connector connections. (damage/pulled-out pins, corrosion)
Repair or replace if necessary.
8
•  Operate the driver's power window using the power window main switch.
•  Does the power window motor operate (rotate)?
Caution
•  If the power window motor temperature is high, the motor may not rotate due to the motor internal bimetal function. Leave it untouched for about 3 min. to cool it down, then reinspect.
Yes
Go to the next step.
No
Replace the power window motor.
(See POWER WINDOW MOTOR REMOVAL/INSTALLATION.)
9
•  Remove the door glass from the carrier plate.
•  Make sure that the door glass moves smoothly using your hand.
•  Does the door glass move smoothly?
Yes
Replace the power window regulator.
(See FRONT POWER WINDOW REGULATOR REMOVAL/INSTALLATION.)
(See REAR POWER WINDOW REGULATOR REMOVAL/INSTALLATION.)
No
Inspect for a bent regulator guide or other possible malfunction. If normal, replace the door glass run-channel.
