Test E: Left Rear Window Is Inoperative
NOTE:
Left rear window control switch harness connector C711 is a flat 4-pin connector. Left rear window control switch harness connector C709 is a square 4-pin connector.
- Turn ignition switch to ON position. Using New Generation Star (NGS) S tester, select and monitor Driver's Door Module (DDM) PID LRPW_SW. Press and release driver's door window control switch left rear window switch in up and down positions several times. If PID agrees with the switch position, go to next step. If PID does not agree with the switch position, replace DDM.
- Attempt to operate left rear window from master window control switch. If left rear window does not operate properly, go to next step. If left rear window operates properly, go to step 9 .
- Turn ignition switch to OFF position. Disconnect left rear window control switch harness connector C711. Turn ignition switch to ON position. Measure voltage between ground and Yellow/Light Blue wire terminal at left rear window control switch harness connector C711 while pressing master window control switch left rear window to up position. Measure voltage between ground and Gray/Orange wire terminal at left rear window control switch harness connector C711 while pressing master window control switch left rear window to down position. Voltage should cycle from zero volts to battery voltage when switches are pressed. If voltage is as specified, go to next step. If voltage is not as specified, go to step 7 .
- Disconnect left rear window control switch harness connector C709. Measure voltage between ground and Yellow/Light Green wire terminal at left rear window control switch harness connector C709. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Yellow/Light Green wire.
- Turn ignition switch to OFF position. Measure resistance between ground and Black wire terminal at left rear window control switch harness connector C709. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Black wire.
- Test left rear window control switch. See SINGLE SWITCHES under COMPONENT TESTS. If left rear window control switch is okay, go to step 8 . If left rear window control switch is defective, replace switch.
- Disconnect DDM harness connector C523. Measure resistance of Yellow/Light Blue wire between terminal No. 1 at DDM harness connector C523 and left rear window control switch harness connector C711. See Fig 1 . Measure resistance of Gray/Orange wire between terminal No. 2 at DDM harness connector C523 and left rear window control switch harness connector C711. If any resistance is greater than 5 ohms, repair open in Yellow/Light Blue and/or Gray/Orange wire. If all resistances are 5 ohms or less, replace DDM.
- Disconnect left rear window motor harness connector C710. Measure resistance of Yellow/Black wire between left rear window control switch harness connector C711 and left rear window motor harness connector C710. Measure resistance of Yellow/Light Blue wire between left rear window control switch harness connector C711 and left rear window motor harness connector C710. If any resistance is greater than 5 ohms, repair open in Yellow/Black and/or Yellow/Light Blue wire. If all resistances are 5 ohms or less, replace left rear window motor.
- Disconnect left rear window control switch harness connector C711. Turn ignition switch to ON position. Measure voltage between ground and Red/Light Blue wire terminal at left rear window control switch harness connector C711. If battery voltage exists, replace left rear window control switch. If battery voltage does not exist, repair open in Red/Light Blue wire.
