One Power Window Inoperative

  1. Check Window Operation  - Turn ignition off. Operate all windows from master switch. If all windows open and close properly, go to 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, go to step 4). 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 step 5). If either rear window does not operate, go to step 8).
  4. Check Left/Front Power Window Circuits  - Turn ignition off. Disconnect master switch harness connector. Disconnect left/front window motor harness connector. Measure resistance of the Red/Black and Red/Green wires between the master switch harness connector and left/front window motor harness connector. Measure resistance between ground and Red/Black and Red/Green wires. If resistance measurements indicate open or shorted circuit, repair wire(s) as necessary. If resistance measurements indicate circuits are okay, replace left/front window motor.
  5. Check Right/Front Power Window Switch  - Perform single switch test on suspect switch. See SINGLE SWITCH  under COMPONENT TEST. If right/front switch is okay, go to next step. If right/front switch is faulty, replace right/front switch.
  6. Check Right/Front Switch Circuits  - Turn ignition off. Disconnect master switch. Disconnect right front window switch. Measure resistance of Black/Blue, Green/White and Red/White wires between master switch harness connector and right/front window switch harness connector. If resistance of all wires is less than 5 ohms, go to next step. If resistance of any wire is greater than 5 ohms, repair wire in question.
  7. Check Right/Front Motor Circuits  - Turn ignition off. Disconnect right/front window motor harness connector. Ensure right/front window switch is disconnected. Measure resistance of Red and Green wires between right front window switch harness connector and right/front motor harness connector. Measure resistance between ground and Red and Green wires. If resistance measurements indicate open or shorted circuit, repair as necessary. If right/front window switch-to-motor circuits are okay, replace window motor.
  8. Check Power Supply To Rear Window Switches  - Turn ignition off. Unplug suspect rear window switch. Ensure lock-out switch on master control switch is in POWER ON position. Turn ignition on. Measure voltage of Black/Blue wire at suspect rear window switch harness connector. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair Black/Blue wire.
  9. Check Rear Window Switch  - Turn ignition off. Test suspect rear window switch. See SINGLE SWITCH  under COMPONENT TESTING. If switch is faulty, replace switch in question. If switch is okay, go to next step.
  10. Check Master Switch-To-Single Switch Circuits  - Turn ignition off. Unplug master switch. Unplug suspect rear window switch. Check continuity of suspect wires. Check for short to ground of suspect wires. See REAR WINDOW SWITCH CIRCUIT IDENTIFICATION  table. If all circuits are okay, go to next step. If any circuit is open or shorted to ground, repair as necessary.
    REAR WINDOW SWITCH CIRCUIT IDENTIFICATION

    Application Wire Color At Master Switch Wire Color At Single Switch
    Left/Rear Green/Yellow Blue/White
    Left/Rear White/Red Yellow/White
    Right/Rear Blue/White Blue/White
    Right/Rear Yellow/White Yellow/White
  11. Check Rear Motor Circuits  - Turn ignition off. Disconnect suspect rear window motor harness connector. Ensure suspect rear window switch is disconnected. Measure resistance of Red and Green wires between suspect rear window switch harness connector and motor harness connector. Measure resistance between ground and Red and Green wires. If resistance measurements indicate open or shorted circuit, repair as necessary. If circuits are okay, replace window motor.
