No.2 THE DRIVER'S SIDE POWER WINDOW IS INOPERATIVE [POWER WINDOW SYSTEM]

id0903a0831100

2 | The driver’s side power window is inoperative
POSSIBLE CAUSE | • Power supply circuit or ground circuit malfunction ― Burnt fuse (B+) ― Open or short circuit in wiring harness between fuse (B+) and power window main switch ― Open or short circuit in wiring harness between power window main switch and power window motor ― Open or short circuit in wiring harness between power window main switch and ground • Power window main switch malfunction • Power window motor malfunction • Power window regulator malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Turn the ignition switch to the ON position. • Does the LED on the power window main switch illuminate? | Yes | Go to Step 5.
No | Go to the next step.
2 | • Operate passenger’s side power 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 20 A fuse—Power window main switch terminal B (Auto on both driver and passenger side) / I (Auto on driver side only) • Power window main switch terminal G (Auto on both driver and passenger side)—ground. Repair or replace if necessary.
3 | • Is the P.WIND 20 A fuse normal? | Yes | Replace the power window main switch. (See POWER WINDOW MAIN SWITCH INSPECTION.)
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. (power window motor output terminal) while operating the power window using the power window main switch. • Is the voltage B+? L.H.D.model (Auto on both driver and passenger side): open: terminal J/close: terminal I L.H.D.model (Auto on driver side only): open: terminal B/close: terminal G R.H.D.model: open: terminal F/close: terminal D | Yes | Go to the next step.
No | Replace the power window main switch. (See POWER WINDOW MAIN SWITCH INSPECTION.)
6 | • Measure the voltage at the power window motor. (battery power supply terminal) while operating the power window using the power window main switch. • Is the voltage B+? (Open: terminal A/ close: terminal G) | 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.
7 | • Operate the driver’s side 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 REGULATOR REMOVAL/INSTALLATION.)
8 | • 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 POWER WINDOW REGULATOR REMOVAL/INSTALLATION.)
No | Inspect for a bent regulator guide or other possible malfunction. If normal, replace the door glass run-channel.
