One Power Window Inoperative

  1. Check Window Operation

    Turn ignition off. Operate all windows from master switch. If all windows open and close properly, goto step 3). If all windows do not operate from master switch, go to next step.

  2. Check Master Switch

    Perform master switch test. See MASTER SWITCH  under COMPONENT TESTING. If master switch is faulty, replace master switch. If master switch is okay and left front window is inoperative, see ONE-TOUCH DOWN FEATURE INOPERATIVE test. If master switch is okay and any other window is inoperative, go to next step.

  3. Check Remote Operation

    Turn ignition off. Reconnect master switch harness connector. Turn ignition on. Press power window lock-out switch to POWER ON position (located on master switch assembly). Operate all passenger windows from the individual (not master) switches. If all windows operate, advise customer of lock-out switch. If right/front window does not operate, go to next step. If either rear window does not operate, go to step 7).

  4. Check Voltage To Right/Front Window Switch

    Turn ignition off. Unplug right front window switch connector. Turn ignition on. While operating right front window from driver's master switch to UP position, measure voltage between right front window switch connector terminal Green/Black wire and ground. While operating right front window from driver's master switch to DOWN position, measure voltage between right front window switch connector terminal Red/White wire and ground. If voltages are greater than 10 volts, go to next step. If voltage of either wire is less than 10 volts, repair wire in question.

  5. Check Right Front Motor Circuits

    Turn ignition off. Measure resistance between right front power window switch connector White and Red wire terminals. Resistance should be less than 5 ohms. Measure resistance between ground and right front power window switch connector White wire, and Red wire individually. Resistances should be greater than 10 k/ohms. If all resistances are as specified, replace right front power window switch. If resistances are not as specified, go to next step.

  6. Check Right Front Window Motor Operation

    Perform power window motor test. See POWER WINDOW MOTOR  under COMPONENT TESTING. If left front power window motor is faulty, replace left front power window motor. If left front power window motor is okay, repair circuit(s) between right front power window switch and right front power window motor.

  7. Check Rear Window Switch

    Perform single switch test. See SINGLE SWITCH  under COMPONENT TESTING. If rear window switch is faulty, replace rear window switch. If rear window switch is okay, go to next step.

  8. Check Voltage To Rear Window Switch

    Turn ignition off. Unplug appropriate rear window switch connector. Turn ignition on. While operating appropriate rear window from driver's master switch to UP position, measure voltage between appropriate rear window switch connector terminal Blue/White wire and ground. While operating appropriate rear window from driver's master switch to DOWN position, measure voltage between rear window switch connector terminal Yellow/Green wire and ground. If voltages are greater than 10 volts, go to next step. If voltage of either wire is less than 10 volts, repair wire in question.

  9. Check Rear Window Motor Operation

    Perform power window motor test. See POWER WINDOW MOTOR  under COMPONENT TESTING. If rear power window motor is faulty, replace rear power window motor. If rear power window motor is okay, repair circuit(s) between rear power window switch and rear power window motor.
